Cone & Thread Fittings Supplier in Texas: US-Serving Manufacturer

Cone and thread fittings in Texas are high-pressure, coned-and-threaded instrumentation fittings, gland-and-collar connections made up onto coned-and-threaded high-pressure tubing, and they carry chemical-injection, hydraulic, autoclave and pressure-test service to 30,000 psi across the state's Permian and Eagle Ford wellsites, Gulf Coast refineries and high-pressure process skids. Crestflo supplies cone and thread fittings throughout Texas as a US-serving manufacturer. The fittings are machined from high-tensile stainless, offered in NACE-ready exotic alloys, built to the standardized high-pressure cone-and-thread envelope, and delivered in 6–8 weeks. We supply Texas; we aren't located there. These are instrumentation- and high-pressure-grade stainless and alloy cone-and-thread fittings meant for pressurized fluid and gas systems. They aren't plumbing fittings, and this isn't a thread-cutting reference.

Also Known As: Coned-and-Threaded, Gland-and-Collar & Medium/High-Pressure Fittings

Buyers across Texas order this hardware under a handful of different names. Cone and thread fittings show up as coned-and-threaded fittings, gland-and-collar fittings, medium- and high-pressure (MP/HP) fittings, high-pressure tube fittings, and sour-gas or frac fittings. Specs often reference a competitor pattern too, something like Parker Autoclave Engineers® or HiP® high-pressure fittings. The connection itself works by coning and threading the tube end, then compressing it with a gland (nut) and collar (sleeve) to form a metal seal rated well above what a compression ferrule joint can handle.

Configurations span glands, collars, adapters, couplings, elbows, tees, crosses and reducers, along with nipples and coned-and-threaded high-pressure tube. All of it comes in NPT, medium-pressure and high-pressure thread forms. Crestflo supplies the full cone-and-thread range under every one of these designations, acting as a cone and thread fittings supplier, manufacturer, distributor, vendor and company serving the Texas (TX) market. The company also works as an OEM private-label source and distributor line card.

Texas Cone & Thread Fitting Demand: Who Buys High-Pressure Fittings Here

Texas holds the densest concentration of instrumentation-fitting demand in the United States. Cone and thread fittings are the go-to connection wherever service pressure climbs past what a compression fitting can handle. The heaviest demand sits in upstream oil and gas: Permian Basin operators around Midland and Odessa, Diamondback Energy, Discovery Operating and the wider RRC District 8 sour-gas belt, along with the Eagle Ford play running the San Antonio, Laredo corridor, all put coned-and-threaded fittings to work on chemical-injection, wellhead, frac and high-pressure hydraulic lines.

Across the Houston Ship Channel and Golden Triangle, refining and petrochemical plants, Motiva Port Arthur, ExxonMobil Baytown and Beaumont, Marathon Galveston Bay, Chevron Phillips Cedar Bayou, Dow Freeport, rely on high-pressure cone-and-thread fittings for hydraulic power units, pressure-test rigs and analyzer sample lines. Hydraulic systems statewide reach for the same coned connection whenever a re-makeable metal seal has to hold up under shock and vibration at pressure.

These facilities are cited as regional operating conditions Crestflo specs cone and thread fittings for. They aren't claims of a supply relationship or an endorsement.

Cone & Thread Fitting Specs at a Glance: Sizes, Pressure, Connections & Alloys

Full specifications and configuration options sit on the national high-pressure cone & thread fittings hub, part of the broader high-pressure fittings & valves range. That range covers the 15,000 psi and 20,000 psi classes. Crestflo sets these figures to the applicable standard. Each one can be adjusted to fit specific requirements.

Recommended Alloys & Specs for Texas Cone & Thread Fitting Service

Texas runs four distinct service regimes, and each one ties a service driver to a specific cone-and-thread alloy and governing standard. High-pressure cone-and-thread fittings answer the sour and high-pressure oilfield regimes most directly. In chemical-injection, wellhead and frac lines, pressure and H₂S show up together, and that combination demands both a metal-sealed high-pressure joint and a corrosion-resistant alloy.

Explore the metallurgy on the 316/316L, Inconel 625, Super Duplex 2507 and Monel K500 material pages. You can also browse by standard, through NACE MR0175 and ASME B31.3, or by service, using the sour-service NACE selection and cone-and-thread vs compression guides. Crestflo makes instrumentation cone-and-thread fittings in each of these grades. Values follow the applicable standard and can be adjusted to requirement.

Texas Basin & Cluster Map: Where Cone & Thread Fittings Ship

Crestflo handles one Texas plant footprint across four service regimes: a Permian sour-gas chemical-injection line, a Golden Triangle pressure-test rig, and a Corpus Christi high-pressure instrument line. For each, they spec the correct cone-and-thread alloy and bore. Every piece is traceable, marked, and dimensionally matched to your existing high-pressure cone-and-thread envelope.

US-Serving Manufacturer Supplying Texas: Lead Time & Logistics

Crestflo manufactures in India and carries no US warehouse. The framing for a Texas buyer stays honest and simple: ready stock for standard items, made-to-order for specials, and 6–8 week door delivery, against the 20+ weeks typical for the majors. An RFQ returns an engineered quote in days.

Ocean freight naturally routes through the Gulf Coast ports closest to Texas demand: Port Houston, the largest US port complex by total waterborne tonnage, and the Port of Corpus Christi, the third-largest US port by tonnage and a top crude and LNG export gateway. Inland distribution then covers the Dallas, Fort Worth, Austin and San Antonio corridors, serving the semiconductor and South Texas markets.

Crestflo cone and thread fittings are machined to the standardized medium- and high-pressure coned-and-threaded geometry. That means they interchange dimensionally with the major high-pressure patterns and drop right into an existing installed base. The separate compression tube fitting line goes further still, performance-qualified to ASTM F1387.

Standard product is of Indian origin and isn't TAA-compliant. US or European melt is available on request, with full material traceability, for cases where a domestic-melt or TAA basis is required. See US-origin compliance and lead time.

Standards, Certifications & Traceability for Texas Cone & Thread Fittings

Crestflo machines its cone and thread fittings from high-tensile stainless, built to the established medium- and high-pressure cone-and-thread envelope and pressure-rated per ASME B31.3 for the line class. For Permian and Eagle Ford H₂S exposure, sour-service fittings ship NACE MR0175 / ISO 15156 compliant. Each fitting carries a heat-number mark for full traceability. EN 10204 3.1 material test certificates come standard, and 3.2 is available on request. In-house NDT and PMI, along with hydraulic proof, burst and impulse testing, back up the quality regime. Crestflo holds ISO 9001 / 14001 / 45001 and PED certification, and the certificates are on file, available through the quality and traceability pages. Certifications are stated as conformance to the standard approvals that apply to high-pressure cone-and-thread fittings. Worth noting: ASTM F1387 governs compression tube fittings, not cone-and-thread connections.

Buy Cone & Thread Fittings for Texas: Distributor, OEM & RFQ Paths

Crestflo serves every buyer type sourcing cone and thread fittings in Texas: master distributors and distributors building a line card, equipment manufacturers designing high-pressure and injection skids to print, OEMs needing private label, and end users, plant and MRO teams, EPC contractors and panel fabricators, needing a fast RFQ. Distributors can request a line card through the distributor program. OEMs can apply through the private-label program, and plant, MRO, EPC and panel-fabrication buyers can get a fast quote or sample. The coned-and-threaded connection follows established high-pressure dimensions, so Crestflo cone and thread fittings interchange with the incumbent envelope. Ask the engineering team for your Parker Autoclave Engineers® or HiP® cross-reference rather than working from a fixed part-number chart. Datasheets and CAD models are available to customers on request.

Request a quote for cone and thread fittings in Texas through request a quote, or start with a sample request; engineered quotes typically come back within 24-48 hours. For US sales, reach out at sales@crestflousa.com or +1 346 594 9005. Crestflo's team is ready to help.
