Also Known As: Big Spring Tube Fittings, Instrument Valves & Manifolds
Buyers across Big Spring and Howard County ask for this hardware under a handful of names. Compression tube fittings get called double-ferrule fittings, single-ferrule fittings, instrumentation fittings, or just "tube fittings," and wellsite and refinery specs often reference them by a competitor pattern such as Swagelok®, Parker A-LOK®/CPI®, Hoke® or Hy-Lok®. Instrument valves cover needle, ball, check (NRV), bleed, gauge-root and metering valves. Multi-port assemblies go by 2-, 3- and 5-valve manifolds, or monoflange and double-block-and-bleed (DBB) valves. High-pressure connections on frac, injection and test lines are known as cone-and-thread or medium- and high-pressure fittings.
Crestflo supplies the full instrumentation range under every one of these names, whether you're looking for a supplier, a manufacturer, a distributor line card or an OEM private-label source, for the Big Spring, TX market.

Serving Howard County: Spraberry & Wolfcamp Wellsites, the Delek Refinery & Rail Terminals
Big Spring sits as the seat of Howard County in the eastern Midland Basin of the West Texas Permian, and Crestflo engineers to the real service conditions found across the region's named clusters. Upstream, Howard County produced roughly 5.0 million barrels of oil in April 2026, the seventh-highest total of any Texas county, pulled from Spraberry and Wolfcamp horizontals worked by operators including Occidental (Oxy), Chevron U.S.A., SM Energy, APA/Apache, Ovintiv USA, Surge Operating, Citation Oil & Gas, Grayrock Energy II, New Height Energy, Birch Operations and Hibernia Resources IV, with regional drilling contractors such as Robinson Drilling of Texas rounding out the picture.
In town, the Delek US Big Spring Refinery runs as a 73,000 bpd integrated cracking refinery (Nelson Complexity Index 10.5) spread across 1,306 acres, turning out transportation fuels, solvents, finished asphalt and LPG. Work underway there includes a crude-unit expansion, a diesel hydrotreater and reformer upgrades, a benzene stripper addition, and a DOE-selected carbon-capture project. Each of these is a fresh source of instrumentation and valve tie-in demand.
Midstream, the Delek Logistics Big Spring crude-gathering system handles Midland Basin gathering with LACT and saltwater-disposal instrumentation. The Twin Eagle Permian Rail Terminal and the Big Spring Rail System short line, which interchanges with Union Pacific at Big Spring Yard, move energy and bulk freight through the area. Crestflo cites these facilities as regional operating conditions it specs for, not as claims of supply relationship or endorsement.
Alloys for Big Spring Sour-Gas, Produced-Water & Refinery Service Conditions
The eastern Midland Basin runs on sour gas. Permian associated gas and produced fluids carry H₂S, and sour service kicks in once H₂S partial pressure climbs above roughly 0.05 psia per ISO 15156-1. That's why the main material requirement on wetted instrumentation is NACE MR0175 / ISO 15156 compliance. High-pressure Spraberry and Wolfcamp production piles on frac and wellhead duty. Chloride-rich produced water from gathering and saltwater disposal drives pitting and stress-corrosion cracking that plain 316 can't withstand, and the Delek refinery's hydrotreating, reforming, benzene/solvent, asphalt and future CCS service brings mixed hydrocarbon, hydrogen and amine/sour-water streams at elevated temperature. Each of these maps to a specific alloy and governing standard.
| Big Spring-area service condition | Corrosion driver | Recommended alloy(s) | Governing spec | Crestflo product form |
|---|---|---|---|---|
| Permian sour gas (defining local condition) | Wet H₂S, SSC / HIC / SOHIC | Controlled-hardness 316/316L, Duplex 2205, Super Duplex 2507, Inconel 625, Incoloy 825, Monel 400 | NACE MR0175 / ISO 15156 | Compression fittings, needle, gauge-root & manifold valves |
| High-pressure production (frac/wellhead) | High-pressure gathering & injection duty | High-tensile SS, Inconel 625 | High-pressure design per applicable standard | Cone-and-thread fittings (to 30,000 PSI), high-pressure valves |
| Chloride-rich produced water & SWD | Chloride pitting & SCC (high-TDS) | Super Duplex 2507, 254 SMO, AL-6XN, 904L, Alloy 20 | High-PREN alloy selection per applicable standard | Tube fittings, ball & check valves, tubing |
| Refinery process service (Delek) | Hydrogen, amine/sour-water, elevated temperature | 316/316L and nickel alloys | NACE MR0175; refinery process design per applicable standard | Process fittings & valves, thermowells, manifolds |

Delivery & Lead Time to Big Spring via the Port of Houston
Crestflo makes its products in India and doesn't operate a US warehouse. For a Big Spring buyer, the pitch is straightforward: standard items ship from ready stock, specials get made to order, and delivery to the door runs 6–8 weeks, compared with the 20-plus weeks the major suppliers typically need for NACE and alloy items. Submit an RFQ and you'll get an engineered quote back within days.
Big Spring sits inland in West Texas rather than on a coast. I-20 runs through it, and Union Pacific rail reaches it via the Big Spring Rail System short-line interchange. Midland International Airport is about 53 miles to the west. Ocean freight comes in through the Gulf Coast gateway closest to Permian demand, the Port of Houston, which is the natural entry point for cargo out of India. That's roughly 449 road miles east of Big Spring, about a 7-hour drive, and trucks then carry the inland leg along the I-20 corridor. The Port of Corpus Christi serves as an alternate Gulf gateway for freight bound for West Texas.
Standard product is of Indian origin and isn't TAA-compliant. US or European melt can be arranged on request, complete with full material traceability, for cases where a domestic-melt or TAA basis is required. See US-origin compliance and lead time for details.
Standards, Certifications & Traceability for Big Spring Sour-Service
Crestflo compression tube fittings go through ASTM F1387 testing, the standard that governs performance qualification for compression-tube fittings and anchors dimensional and functional interchange with the majors. Instrument valves qualify to ASME B16.34 and the applicable API standards (not F1387, which covers fittings), and every manifold gets a 100% seat and shell leak test. For sour-service parts headed to the Permian for H₂S applications, Crestflo supplies NACE MR0175 / ISO 15156 compliant components, with hardness controlled on the wetted alloys. Each part carries a heat-number mark for full traceability. EN 10204 3.1 material test certificates come standard, and 3.2 is available on request; PMI and third-party inspection can also be arranged for refinery or DOE/CCS project specs. Crestflo holds ISO 9001 / 14001 / 45001 and PED certification, and those certificates sit on file, accessible through the quality and traceability pages. All certifications reflect conformance to the standard approvals that apply to each product type.

Big Spring Instrumentation FAQ
Do you stock instrumentation fittings in Big Spring or the Permian Basin?
Crestflo doesn't have a US warehouse yet, though it serves the US market as a manufacturer. Standard items come from ready stock, while specials are made to order; either way, parts reach Big Spring in 6–8 weeks. That beats the 20+ weeks typical of the major brands on NACE and alloy items. Goods come in through the Port of Houston and get trucked to the Permian from there. Distributors have the option to run a stocking or consignment program to keep inventory close to home.
Are your fittings and valves NACE MR0175 compliant for Permian sour-gas wells?
Compression fittings, valves and manifolds are available in NACE MR0175 / ISO 15156-compliant versions, yes. They come with the correct wetted-material and controlled-hardness designation for H₂S service, plus heat-number traceability and EN 10204 3.1/3.2 MTCs. Per ISO 15156-1, sour service kicks in once the H₂S partial pressure climbs above roughly 0.05 psia.
Which alloys do you recommend for Howard County sour and high-chloride produced-water service?
316/316L is the starting point, moving up to Inconel 625/825, Incoloy 825, Duplex 2205, Super Duplex 2507, 254 SMO or AL-6XN when H₂S partial pressure and chloride pitting demand more. Values follow the applicable standard and can be adjusted to fit the requirement.
Can you supply high-pressure fittings for Spraberry and Wolfcamp production?
Cone-and-thread fittings rated up to 30,000 PSI, precision fittings good to 15,000 PSI, and high-pressure valves handle frac, injection and high-pressure test lines. Valves and manifolds get leak-tested under our QA regime.
How fast can you deliver to a Big Spring wellsite or the Delek refinery?
Ocean freight lands at the Port of Houston, roughly 449 road miles east, about a 7-hour drive, then it's trucked inland to Big Spring via I-20. RFQ to ship runs about 6-8 weeks plus transit, against the 20+ weeks typical for the majors. There's no US-held counter stock, and origin is disclosed honestly.
Are your parts drop-in replacements for Swagelok or Parker on existing Permian panels?
Crestflo is an independent equivalent to Swagelok®, not affiliated with it, and dimensional interchange is backed by ASTM F1387 performance qualification. This covers imperial and metric sizes, single or double ferrule. Swagelok® is a trademark of Swagelok Company. If you need a cross-reference, just ask the engineering team for one.
What traceability do we get for a refinery or DOE/CCS project spec?
EN 10204 3.1 material test certificates come standard, and 3.2 is available if you ask for it. Every part gets its heat and lot number marked on. PMI and third-party inspection are available on request too. That's the traceability a Delek refinery or a carbon-capture project spec usually calls for.
What is the country of origin, and is it TAA-eligible?
Standard product comes from India and isn't TAA-compliant. US or European melt is available on request, complete with full material traceability, wherever a domestic-melt or TAA basis is needed.
