Cone-and-Thread Fittings Supplier in Kansas
Crestflo supplies cone-and-thread fittings across Kansas, engineered for drop-in replacement and delivered on a 6-8 week build lead time. None of it is shipped from a Kansas warehouse. Our reach covers the Wichita aviation and aerospace core, the self-styled Air Capital of the World, along with the south-central and southeast refining belt at El Dorado, McPherson and Coffeyville. Add the Hugoton natural-gas field in southwest Kansas and the new Panasonic De Soto EV-battery gigafactory in the Kansas City metro, and that's the full territory.
The Kansas market runs on high-pressure, weight-critical metallurgy, and our product line reflects that. High-tensile stainless cone-and-thread fittings rated to 30,000 psi serve Air-Capital hydraulic and test-stand lines. Titanium Gr2 takes care of weight-critical service. Sour-gas refinery work and Hugoton service call for NACE-compliant nickel and duplex grades. Battery-process chemistry runs on 316L and Alloy 20. Standard items ship from ready stock; specials are made to order.
We supply Kansas. We aren't located there. We Engineer Confidence.
In this context, "cone-and-thread fittings" refers to high-pressure instrumentation connections: a coned tube end drawn against a collar by a threaded gland, used for medium- and high-pressure process, gas, hydraulic and test-stand lines. It doesn't mean woodworking cone threads, self-tapping cone screws, or plumbing compression fittings.
What Are Cone-and-Thread Fittings?
Cone-and-thread fittings are high-pressure tube connections: the tube end gets machined to a cone and cut with an external thread, then drawn against a mating collar (or gland) so the coned metal-to-metal seat carries the process seal. The seal comes from the coned tube itself, not a ferrule biting into the tube OD. That's why the joint holds far higher pressures than a conventional single- or double-ferrule tube fitting, and why it's standard for anything well above the compression-fitting range. On Kansas systems, you'll find cone-and-thread joints on Wichita aerospace hydraulic and test-stand rigs, weight-critical aircraft lines, high-pressure refinery and sour-gas take-offs, gas-gathering and processing skids across the Hugoton field, and high-pressure battery-process hookups at De Soto. The focus here is cone-and-thread fittings as supplied to Kansas. For the full ordering matrix and every pressure class, see the national cone-and-thread fittings hub.
Cone-and-Thread Fittings Also Known As
Kansas buyers specify these connections under several names. Cone-and-thread fittings are also called coned-and-threaded fittings, coned & threaded tubing connections, medium- and high-pressure (MP/HP) fittings, high-pressure tube fittings, autoclave-type fittings, and gland-and-collar fittings. On aerospace test stands and gas-processing skids buyers often call out 37° flare (ISO 8434-2) and NPT (ASME B1.20.1) ends for the lower-pressure legs of the same system. Crestflo builds the cone-and-thread line to working pressures up to 30,000 psi and rates the broader high-pressure family across 3,000 psi to 20,000 psi pressure classes on the high-pressure fittings hub, as a cone-and-thread fittings supplier, manufacturer, distributor, vendor and company serving the Kansas (KS) market.
Who Buys Cone-and-Thread Fittings in Kansas
Kansas runs on aviation and refining, and cone-and-thread fittings are the go-to high-pressure connection on its hydraulic, test-stand and gas-processing lines. Demand tracks four real clusters:
- Aviation and aerospace manufacturing, Wichita / Sedgwick County, the primary driver. Spirit AeroSystems, the world's largest first-tier aerostructures maker (Boeing completed its reacquisition of Spirit on 8 December 2025), Textron Aviation (Cessna Citation, Caravan, King Air and the new Beechcraft Denali), Airbus Americas Engineering at the WSU Innovation Campus, and Bombardier's Wichita service and completions center all anchor the "Air Capital of the World." Aircraft hydraulic, test-stand and weight-critical lines run cone-and-thread and 37° flare fittings at high pressure. A base of more than 600 suppliers in landing gear, hydraulics and MRO backs all this up across Sedgwick, Butler and Sumner counties.
- Oil and gas refining plus Hugoton natural gas. HF Sinclair El Dorado (around 135,000 bpd, Butler County), CVR Energy Coffeyville (around 132,000 bpd, Montgomery County), CHS McPherson (around 114,000 bpd), and the Hugoton natural-gas field, which stretches across 14-plus southwest counties, run high-pressure take-offs, well-test and chemical-injection points on refinery and gas-processing service. Some Mid-Continent gas and refinery streams turn sour where H₂S is present, which pushes metallurgy toward NACE and corrosion-resistant alloys.
- EV-battery manufacturing. Panasonic Energy's De Soto gigafactory in Johnson County, the state's largest-ever economic-development project, began mass production of 2170 cylindrical cells on 14 July 2025, with a target of roughly 30–32 GWh/yr. Electrolyte, NMP/cathode-slurry and process-acid lines call for high-purity and acid-resistant fitting selection on the high-pressure side.
- Ag, ethanol and biofuels, wind energy, and salt. Grain-handling, ethanol and biofuels plants, wind generation ranked among the nation's best, and rock-salt mining at Hutchinson in Reno County all run process-instrumentation and utility/steam service in standard 316/316L, switching to chloride-resistant grades wherever brine comes into play.
Crestflo doesn't claim a supply relationship or endorsement by naming these facilities; they're cited as regional operating conditions Crestflo specs cone-and-thread fittings for. Kansas fits this pattern because Air-Capital hydraulic and test-stand rigs, over-pressured sour-gas take-offs and high-pressure battery-process hookups all run pressures that push connections past standard ferrule tube-fitting ratings. That's the same reason aerospace & defense and oil & gas buyers standardize on the coned-and-threaded joint. Served metros and hubs include Wichita, El Dorado, McPherson, Coffeyville, Hutchinson, De Soto and the Kansas City metro, plus the southwest-Kansas Hugoton counties.
Recommended Cone-and-Thread Alloys & Specs for Kansas Service
Kansas isn't a single-threat state; it's a multi-driver region. Aviation high-pressure and weight-critical systems come first, refining and sour-gas corrosion second, battery-process chemistry third. Match the cone-and-thread fitting alloy to the cluster:
| Kansas service condition | Corrosion / service driver | Recommended cone-and-thread alloy / spec | Governing standard |
|---|---|---|---|
| Aviation hydraulic / test-stand & weight-critical (Spirit, Textron, Airbus, Bombardier) | High-pressure, cyclic, cleanliness, weight-critical | High-tensile 316/316L to 30,000 psi and Titanium Gr2 for weight-critical lines; 37° flare (ISO 8434-2) legs; heat-number traceability | ISO 8434-2 / ASTM A479 |
| Refinery / sour-gas, H₂S service (HF Sinclair El Dorado, CVR Coffeyville, CHS McPherson, Hugoton gas) | H₂S / sulfide-stress-cracking risk where present | Inconel 625 / 825, Incoloy 825, Duplex 2205 / Super Duplex 2507 | NACE MR0175 / ISO 15156 |
| EV-battery process chemicals (Panasonic De Soto) | Electrolyte / NMP / cathode-slurry / process acids | 316/316L standard, stepping to Alloy 20, 904L or Hastelloy C-276 where acid or halide chemistry is aggressive | ASTM A276 / A479 |
| Refinery general process + ethanol/biofuels + steam/utility | Hydrocarbons, hot process, glycol/steam, cyclic | 316/316L standard; super-duplex / 6Mo where chloride is a factor | ASTM A276 / A479 |
| Ag/food, wind gearbox/hydraulics, salt/mining (Hutchinson) | Sanitary, chloride (brine), hydraulic | 316/316L standard; 254 SMO / AL-6XN / Alloy 20 in chloride-heavy salt service | ASTM A276 / A479 |
Titanium Gr2 is instrumentation-grade fittings, not pipe, flanges or mill product; Crestflo's highest-value, most-differentiated Kansas demand centers on aviation hydraulic, test-stand and weight-critical service. That means high-tensile 316/316L cone-and-thread rated to 30,000 psi, plus 37° flare per ISO 8434-2, and Titanium Gr2 itself. Refinery and sour-gas work anchors the business a second way, with NACE MR0175 fittings built in Inconel and Duplex. Then there's Panasonic De Soto's EV-battery process chemistry, a distinctive third pillar calling for 316L and Alloy 20.
Sour service isn't a blanket designation. It applies only where H₂S is actually present. Specify your H₂S partial pressure and any Ra target on the RFQ, and Crestflo will manufacture to the applicable standard, customized to what the job actually needs.
One more point worth stating plainly: Crestflo supplies instrumentation only. No pipe, no flanges, no mill product.

Cone-and-thread specs and ordering codes in full sit on the cone-and-thread fittings hub; what follows here is just the Kansas-relevant slice. For the lower-pressure legs of the same Kansas system, the companion connections are 37° JIC flare fittings. Datasheets and CAD drawings go out to customers on request.
Cone-and-Thread vs Compression & Flare Connections
Not every high-pressure line calls for the same joint. The table below sets out the connection classes Crestflo supplies into Kansas, so specifiers can match pressure to method.
| Connection type | Typical pressure class | Sealing method | Best-fit Kansas use |
|---|---|---|---|
| Compression (single/double ferrule) | Up to standard tube-fitting rating | Hardened ferrule on tube OD | Instrument, gauge and impulse hookups |
| 37° flare (ISO 8434-2) | Up to 15,000 psi | Coned tube against 37° seat, threaded nut | Aircraft hydraulics, air and lower-pressure test legs |
| Medium-pressure cone-and-thread | Up to ~20,000 psi class | Coned tube against collar, threaded gland | Gas-processing, injection and well-test skids |
| High-pressure cone-and-thread | Up to 30,000 psi | Coned-and-threaded gland & collar | Air-Capital hydraulic and test-stand rigs, over-pressured sour-gas take-offs |
Choosing between cone-and-thread and compression comes down to rating and service conditions. See cone-and-thread vs compression for the background. From there, our engineering team will confirm the connection and alloy against your specific line conditions.
Standards, Certifications & Proof
Crestflo is ISO 9001 / 14001 / 45001 & PED certified. Cone-and-thread fittings are supplied to the standard approvals applicable to the product type: NACE MR0175 / ISO 15156 for sour service (controlled hardness) where H₂S is present, ASTM A276 / A479 stainless and CRA bar feedstock, ASME B1.20.1 for NPT threads, and ISO 8434-2 for the 37° flare legs of the same system, with material traceability on every part. Cone-and-thread joints interchange dimensionally with standard MP/HP coned-and-threaded envelopes; separately, Crestflo's companion compression tube fittings are performance-qualified to ASTM F1387 for drop-in interchange with Swagelok® and Parker® tube-fitting envelopes (Swagelok® and Parker® are trademarks of their respective owners; interchange/equivalent, not "compatible/intermix"). Certificate numbers are held in our quality system, see quality & traceability. Testing includes hydraulic proof, burst and impulse, pneumatic, and PMI; datasheets and CAD are available to customers on request rather than as public downloads. Crestflo is the instrumentation division of a four-decade-old, Government-of-India-recognized export house with a Middle-East delivery track record.
US-Serving Manufacturer Supplying Kansas: Lead Time & Logistics
Crestflo, a cone-and-thread fittings manufacturer supplying Kansas, is upfront about the freight math even though it's a US-serving manufacturer rather than a Kansas-based one. Standard cone-and-thread fittings ship from ready stock. Specials get made to order. Both run on a 6–8 week delivery from purchase order to shipment, against the 20+ weeks typical of the majors on NACE, alloy and made-to-print items.
No Kansas warehouse exists, and no US-held stock either: product gets made to order (Indian origin, US/European melt on request, with full material traceability), then routed to the Kansas jobsite. Kansas is landlocked and has no seaport, so the practical ocean gateway for India-origin instrumentation runs through the US Gulf via the Port of Houston or New Orleans, then inland by rail and truck. Kansas City happens to be the largest US rail center by tonnage, served by BNSF, Union Pacific and CPKC, with intermodal deconsolidation at BNSF Logistics Park Kansas City (Edgerton). That's the ideal last-leg point for containers railed inland from the Gulf to Wichita or the KC metro.
Critical line items go by air, and the balance travels by ocean and rail. Crestflo presents the honest timeline rather than imply local stock. See US-origin compliance and lead time.

Kansas Cone-and-Thread Fittings FAQ
Do you stock cone-and-thread fittings in Kansas (Wichita or Kansas City)?
No Kansas warehouse, Crestflo serves the whole US as a manufacturer, but that's not one of its bases. Standard cone-and-thread fittings ship from ready stock, while specials get made to order. Either way, expect 6–8 weeks to reach your site in Wichita, El Dorado, McPherson, Coffeyville, De Soto or the KC metro. Because Kansas sits landlocked, freight comes in through the US Gulf, Houston or New Orleans, then moves inland by rail to BNSF Logistics Park Kansas City in Edgerton, Union Pacific and CPKC. Again: no stock warehouse sits in Kansas itself.
How fast can I get cone-and-thread fittings in Kansas?
Lead time runs 6–8 weeks from PO to shipment, against 20+ weeks typical for the majors, and that includes ocean and inland-rail transit via the US Gulf to the Kansas City rail hub. For urgent Wichita or KC-metro MRO needs, we can air-freight the critical line items and move the rest by ocean and rail.
Do you supply high-pressure and 37° flare cone-and-thread fittings for Wichita aerospace hydraulic and test-stand systems?
Yes: high-pressure cone-and-thread fittings to 30,000 psi, 37° flare fittings per ISO 8434-2 to 15,000 psi, and Titanium Gr2 for weight-critical lines. These match the aviation hydraulic and test-stand demand coming from Spirit, Textron, Airbus and Bombardier. Every piece carries heat-number marking with EN 10204 3.1 MTC, and 3.2 is available on request.
Can you supply NACE MR0175 cone-and-thread fittings for Kansas refineries and sour-gas service?
Yes. NACE MR0175 / ISO 15156 compliant cone-and-thread fittings, valves and manifolds in 316L, Duplex 2205/2507 and Inconel 625/825, heat-number marked and traceable, for El Dorado, Coffeyville, McPherson and Hugoton gas where H₂S shows up. Sour service in Kansas is real across parts of the Mid-Continent base, but it isn't uniform. Put your H₂S partial pressure on the RFQ.
What alloy do you recommend for Panasonic De Soto battery-process chemistry?
Hastelloy, Alloy 20, 904L, 316L, and 316 all cover different needs here: 316/316L for standard electrolyte and DI service, then stepping up to Alloy 20, 904L, or Hastelloy wherever the acid or halide chemistry gets aggressive. High-purity builds handle the solvent-critical NMP and slurry lines. Fittings arrive as cone-and-thread and high-pressure types, each marked with heat numbers and fully traceable.
What pressure can Crestflo cone-and-thread fittings hold?
Cone-and-thread fittings carry a rating up to 30,000 psi. Medium-pressure cone-and-thread and 37° flare fittings (to 15,000 psi) are rated per the applicable standard. We check the working-pressure class against your line conditions and alloy. Values follow the applicable standard and can be adjusted to your requirement.
Are your cone-and-thread fittings drop-in replacements for Swagelok or Parker, and what is the real lead time?
Cone-and-thread joints match standard MP/HP coned-and-threaded envelopes dimensionally, and our companion compression tube fittings drop in with interchange backed by ASTM F1387, both imperial and metric. Swagelok® and Parker® are trademarks of their respective owners; we're talking interchange and equivalence here, not "compatible" or "intermix." Build-to-ship runs 6–8 weeks, plus transit time, and we'll air-freight critical items when needed. We don't publish a part-number table. Ask our engineering team for your cross-reference instead.
Do you sell cone-and-thread fittings to distributors or offer private label in Kansas?
Yes, we handle both, line-card and stocking programs for distributors, plus private-label and made-to-print cone-and-thread fittings for OEMs. Both run on the same 6–8 week build lead time.
Is there a cone-and-thread fittings supplier near me in Kansas, and can I buy cone-and-thread fittings for sale locally?
Crestflo doesn't run a walk-in counter or warehouse in Kansas. It manufactures for customers across the US and supplies cone-and-thread fittings throughout Kansas on a 6-8 week build. Product moves through the US Gulf and inland rail to BNSF Logistics Park Kansas City in Edgerton, then out to Wichita, El Dorado, McPherson, Coffeyville, De Soto or the KC metro. You order through an RFQ. There's no over-the-counter pickup.
