OEM Instrumentation Tube Fittings & Valves: Private-Label and Volume Supply
Crestflo makes instrumentation tube fittings, valves, regulators and tubing, sold in volume to OEMs and optionally private-labeled under your own brand. Fittings offer ASTM F1387 drop-in interchange. Every part carries a heat number, and material test certificates come standard under EN 10204. Delivery runs 6-8 weeks.
Crestflo is a manufacturer, not a reseller. That means it supplies brand owners, product companies and resellers who put instrumentation components into their own catalog or equipment. What these customers need is consistent quality, documentation their own customers can trust, and a lead time they can plan around. We Engineer Confidence.
This OEM program covers instrumentation tube fittings, valves, regulators and tubing in stainless and high-nickel alloys. It doesn't cover plastic push-fit connectors, hydraulic hose fittings, or automotive and plumbing parts. If you build equipment and need design-in and made-to-print support, see the OEM and design-in track for equipment manufacturers. If you resell rather than rebrand, check the distributor line card instead. Everything here leads to one action: an OEM quote for your program.
OEM Tube Fittings & Valves, Also Specified As
Buyers describe this program under many names on a bill of materials or an RFQ. Some write OEM tube fittings, OEM instrumentation fittings, OEM compression fittings, OEM stainless steel fittings, private-label tube fittings, private-label instrumentation fittings, private-label valves, white-label, own-brand or own-brand instrumentation fittings, and contract-manufactured fittings and valves. On the valve side, the same request shows up as OEM valves, OEM valve supplier, OEM ball, needle and manifold valves, or OEM instrumentation valves. On the tubing side it's an OEM tubing supplier. Flip it around and you get tube fittings for OEMs or fittings for OEM manufacturers, or shorten it further to an OEM partner or OEM program. All of these point to the same offer: Crestflo as an OEM fittings manufacturer, OEM contract manufacturer, volume tube fitting supplier, custom tube fittings manufacturer, and private-label supplier of instrumentation-grade components.
Two Ways to Run an OEM Program: Private-Label & Contract/Volume Supply
There are two ways to work with Crestflo as an OEM. You can buy Crestflo's standard instrumentation product under your own brand, fittings and valves alike, laser-marked to your logo, through the private-label instrumentation fittings program, or you can have parts made to your print or specification through custom and made-to-print manufacturing. Both run on in-house CNC, VMC, EDM and milling, and both carry the same traceability and testing regime as catalog product.
| Model | What you get | Best for | Where detail lives |
|---|---|---|---|
| Private-label | Crestflo standard product marked to your brand | Resellers and brand owners | Private-label program |
| Contract / volume | Parts made to your print or spec, in volume | Product companies and integrators | Custom manufacturing |
| Design-in / R&D | Engineering collaboration before the part is fixed | New product development | R&D and design support |

OEM Alloys: 316L Stainless to Inconel, Monel, Hastelloy & Titanium
Crestflo runs OEM volume across stainless, duplex, super-austenitic, nickel and titanium alloys, the corrosion-resistant grades that sour, offshore, cryogenic and high-purity service demand. That includes grades supplied to NACE MR0175 / ISO 15156 where specified. Brass isn't a headline OEM material. Alloys are offered only in instrumentation forms: fittings, valves, tubing.
| Alloy class | Grades | Notes |
|---|---|---|
| Stainless steel | 304/304L, 316/316L, 904L | Standard instrumentation range |
| Duplex & super-austenitic | Duplex 2205, Super Duplex 2507, 254 SMO (6Mo), AL-6XN, Alloy 20 | Chloride and offshore service |
| Nickel alloys | Inconel 600/601/625/718/825, Incoloy 800/800H/825, Monel 400/K500, Hastelloy C-276/C-22/B-2/B-3/X, Nickel 200/201 | Sour and high-temperature service |
| Titanium | Titanium Gr2 | Corrosion and weight-critical service |
Grade selection and the full instrumentation material range get covered on the materials pages. They walk through each alloy and link out to the instrumentation forms Crestflo supplies.
Crestflo OEM Program vs a Generic Overseas Supplier
Crestflo usually gets stacked up against a look-alike import supplier by OEM buyers. The real difference comes down to proof: performance qualification, a full alloy range, per-part traceability, and a documented origin, published as plain data rather than buried in a PDF.
| Attribute | Generic import supplier | Crestflo OEM program |
|---|---|---|
| Interchange proof | "Compatible" claim, unqualified | Dimensional interchange qualified to ASTM F1387 (fittings) |
| Alloy range | Mostly 304/316 | 316L through Hastelloy, Inconel, Monel, Duplex, Titanium |
| Private label | Rarely offered | Own-brand marking, small MOQ |
| Traceability | Batch, if any | Heat/lot number on every part; EN 10204 3.1, 3.2 on request |
| Origin disclosure | Opaque | Indian origin stated; US/European melt on request |
| Quality system | Unstated | ISO 9001 / 14001 / 45001 & PED certified |
| Lead time | Undisclosed | 6-8 week delivery |
Standards & Proof: F1387 Fittings, ASME B16.34/API Valves & EN 10204 MTCs
Crestflo compression tube fittings, tested and qualified to ASTM F1387, the compression-tube-fitting performance standard, sit at the center of this program: the documentation an OEM hands its own customers. They're engineered for dimensional drop-in interchange with Swagelok®, Parker®, Hoke®, Hy-Lok® and Fitok® fittings. Instrumentation valves follow a different path. They're built and qualified to the standards that actually govern valves, ASME B16.34 and the applicable API series (6D, 598, 602), not F1387. Products reference ASTM A269/A276/A479, ASME B16.11 and B1.20.1, ISO 8434-2 (37° flare), DIN 2353 (bite-type), and NACE MR0175 / ISO 15156 for sour service.
Crestflo is ISO 9001 / 14001 / 45001 & PED certified, with certificate documentation held on the quality system page. Every part carries a heat/lot number with an EN 10204 3.1 material test certificate as standard and 3.2 on request; positive material identification (PMI), in-house NDT, and a documented hydraulic, pneumatic, fatigue, vibration and leak-test regime back the program, with third-party inspection available on request. Detail lives at traceability and testing & inspection.
Swagelok® is a trademark of Swagelok Company. Parker® belongs to Parker Hannifin, Hoke® to Hoke, Inc., Hy-Lok® to Hy-Lok Corporation, and Fitok® to FITOK Group. The interchange language here stays precise: these are independently manufactured parts, engineered for equivalent form and fit. They're dimensionally interchangeable. Nothing more. We won't call them "compatible," "identical," or "genuine."
Crestflo isn't affiliated with, authorized by, or endorsed by any of these companies. We don't publish brand-by-brand part-number tables either. What we do instead: request your Swagelok® or Parker® cross-reference from our engineering team.

Why Crestflo for OEM Supply
Crestflo is a new manufacturing brand, though the organization behind it isn't new at all: it's the instrumentation division of a Government-of-India-recognized export house with roughly four decades of trading under its belt and a proven delivery record across Middle-East markets. For an OEM, that heritage translates into a supply chain backing five differentiators that actually matter to a brand program: F1387-qualified drop-in fittings, 6-8 week delivery against the 20-plus weeks common among the majors, small MOQ with private label, made-to-print manufacturing, and cost-competitive landed pricing after US tariffs. Instead of inventing project case studies for a young brand, Crestflo draws on that parent company's history and lays out its proof stack as plain data.

Frequently Asked Questions
Can I put my own brand on Crestflo fittings and valves?
Yes. Crestflo runs a private-label program, with own-brand marking on standard product and small minimum order quantities. You'll find the program details on the private-label capability page.
What is the minimum order quantity for an OEM program?
Small MOQs are available for both private-label and volume supply. The exact tiers depend on the product family and the alloy, and we confirm them with your quote rather than publishing a fixed number.
What lead time applies to OEM and private-label orders?
Ready stock covers standard items; specials get made to order. Delivery runs 6-8 weeks, against the 20-plus weeks common for the major brands. Standard-item stock is held at origin.
Are your fittings interchangeable with Swagelok, Parker or Hy-Lok?
Crestflo compression tube fittings are built for dimensional interchange, qualified to ASTM F1387. Crestflo sticks with "interchange" and "equivalent" here, never "compatible." Brand names belong to their respective owners, and Crestflo isn't affiliated with any of them. If you need a cross-reference, ask the engineering team for one.
What do JIC fittings stand for, and do you make them?
Crestflo builds 37° flare fittings to ISO 8434-2, in sizes up to 2" OD, in volumes ready for OEM work. JIC is simply the name for that 37° flare connection, spelled out in SAE J514.
What materials can you run for OEM volume?
The core lineup runs through stainless grades like 304, 304L, 316, 316L and 904L, then moves into duplex and super-austenitic types: 2205, 2507, 254 SMO, AL-6XN and Alloy 20. Nickel alloys fill out the rest of the list, including Inconel, Incoloy, Monel, Hastelloy and Nickel 200/201, alongside Titanium Gr2. Brass, though? Not a headline OEM material.
Will each part carry traceable documentation?
Marked with a heat/lot number on every part, with an EN 10204 3.1 material test certificate as standard and a 3.2 available on request. PMI records are included too, for composition verification.
Where are the products made, and are they TAA compliant?
Standard product comes from India, though US or European melt is available on request, along with full material traceability when a domestic-melt or TAA-eligible source is needed. Crestflo serves the US market but never claims to be made in USA. TAA and DFARS eligibility get spelled out honestly on the US origin page.
What certifications back the OEM program?
Crestflo holds ISO 9001, ISO 14001, ISO 45001 and PED certification. Its compression tube fittings meet ASTM F1387, and where a job calls for it, NACE MR0175 / ISO 15156 grades are supplied. Valves are qualified to ASME B16.34 and whichever API series applies.
Do you make plastic push-fit or hydraulic hose fittings?
No. Crestflo's OEM scope covers instrumentation fittings, valves, regulators and tubing in metal alloys. Plastic push-fit connectors aren't part of that lineup, and neither are hose or plumbing parts.
Do you offer made-to-print or custom parts?
Yes, send a print, and Crestflo will produce to your drawing using in-house CNC, VMC, EDM and milling. Check the custom manufacturing page for the workflow.
Can you run a kitting, VMI or consignment program?
Yes. Kitting, vendor-managed inventory and consignment are all on the table for OEM and volume accounts. Check the kitting and VMI page for details.
