Instrumentation Fittings & Valves for Equipment Manufacturers
Crestflo is a manufacturer, not a reseller, supplying instrumentation fittings, valves, manifolds, regulators, accessories and tubing to equipment manufacturers who design these components into their own machines, skids, panels and analyzers. We engineer parts in with your team. We build to your print in our own machine shop. We kit or stock them to your bill of materials. Sizes come in both imperial and metric, in stainless steel through high-nickel and corrosion-resistant alloys. Our compression fittings are tested to ASTM F1387 as dimensional drop-in equivalents for the major brands. Standard items ship from ready stock; specials are made to order, with delivery running 6 to 8 weeks.
"Equipment manufacturers" here means OEM builders of machines, skids, panels, analyzers and systems that embed fluid-system instrumentation components. It doesn't mean construction- or agricultural-equipment dealers, and it doesn't mean plumbing hardware either. Every part discussed on this page is instrumentation-grade stainless or high-nickel/CRA. Send a print or request a quote and talk to an engineer at Crestflo.
Also Known As: OEM, Machine-Builder & Skid-Fabricator Component Sourcing
Buyers use a lot of different terms for this program. Equipment manufacturers go by equipment builders, machine builders, OEM equipment manufacturers and original equipment manufacturers. The application-specific builders we serve include skid builders and skid fabricators, package and module assemblers, instrument-panel fabricators, analyzer and sampling-system builders, gas-panel and gas-delivery builders, hydraulic power unit (HPU) builders, test-rig and calibration-equipment builders, and system integrators. The engagement itself gets specified as design-in, made-to-print, build-to-print, print-to-part or contract-manufacturing sourcing. Sometimes it's backed by kitting, vendor-managed inventory (VMI), consignment and blanket-order or long-term-agreement supply. No matter which of these fits your build, the components and programs below stay the same.
What an Equipment Manufacturer Can Design In: Program at a Glance
Every program links out to a capability page for the mechanics, and to the RFQ when it's time to act.
| Program | What it is | Best for | Detail |
|---|---|---|---|
| Design-in engineering support | Talk to an engineer early on alloy, connection and rating selection; prototype quantities | New builds, alloy/media decisions | R&D & design-in |
| Made-to-print / build-to-print | Send a drawing; we machine the part in-house (CNC, VMC, EDM, milling), including custom threads | Non-catalog and custom configurations | Custom manufacturing |
| Kitting & VMI | Kits per assembly or BOM line; consignment/VMI to hold your line; packaging and part marking to spec | Repeat production, line consistency | Kitting & VMI |
| BOM standardization (ASTM F1387) | Consolidate onto one interchangeable line; second-source without redesign | Reducing part count, dual sourcing | ASTM F1387 |
| Private label / OEM-branded | Small-MOQ private-label supply | Branded finished goods | Private label |
Design-In Support: Talk to an Engineer Before the Drawing Is Frozen
Bring us in early, at the design stage. Our engineers will help you pick the right alloy for your media, settle on the end connection and thread standard, set the pressure and temperature rating, and work out the ferrule configuration. From there they supply prototype and pilot quantities so you can qualify the part on your rig before production starts. Take a look at alloy selection and the engineering resources library, or go straight to design-in support with Crestflo.
Made-to-Print & Build-to-Print: Send a Drawing, We Machine the Part
Because we run our own machining, CNC, VMC, EDM and milling, we take design documents all the way to finished parts. Send us a drawing and we'll build to it, including national, international and custom thread forms and configurations you won't find on any catalog page. We support small minimum order quantities and prototype runs too, so a made-to-print special won't carry a mass-production minimum. Crestflo covers this under custom manufacturing.
Kitting & VMI: Hold Your Line on One Consolidated BOM
We build kits by assembly or BOM line, run vendor-managed inventory and consignment to keep your line supplied, and replenish on min-max or Kanban signals, whichever your program prefers. Packaging and part marking follow your spec. Blanket orders and long-term agreements smooth out pricing and availability across a production year. For the mechanics behind the program, see the kitting & VMI page from Crestflo.
Standardize Your BOM on an ASTM F1387 Drop-In Line
Crestflo compression fittings drop straight in as dimensional equivalents for Swagelok, Parker, Hoke, Hy-Lok and Fitok, qualified per ASTM F1387. That means an equipment builder can consolidate a mixed BOM onto one interchangeable line and second-source without redesigning the assembly. We publish the interchange narrative rather than a part-number table. To match the exact part you buy today, request your cross-reference from our engineering team. (Swagelok®, Parker®, Hoke®, Hy-Lok® and Fitok® are trademarks of their respective owners; parts are offered as dimensional interchange/equivalents, not as genuine or intermixed components.)
Product Scope for Equipment Manufacturers: Fittings, Valves, Regulators & Tubing

Crestflo vs. the Major Brands for OEM Design-In
| Buying factor | Crestflo | Typical major brand |
|---|---|---|
| Supplier type | Manufacturer with in-house machining | Manufacturer + distributor network |
| Made-to-print on catalog geometry | Yes, send a drawing | Rarely offered |
| Minimum order quantity | Small MOQ; prototype/pilot supported | Higher minimums |
| Lead time | 6–8 week delivery | 20+ weeks common |
| BOM standardization | ASTM F1387 drop-in across one line | Brand-locked |
| Spec & program data | HTML-native, extractable | Often buried in PDFs |
Crestflo fills the gap on manufacturer flexibility: made-to-print work, small MOQs, kitting and VMI, and a 6-8 week lead time. Pair that with an ASTM F1387 interchange basis, and you can standardize and second-source without touching your design.
Standards, Traceability & Proof for OEM Bills of Material
Crestflo is ISO 9001 / 14001 / 45001 & PED certified, and it holds the standard approvals that apply to each product type. Compression fittings get tested to ASTM F1387. Instrumentation valves qualify to ASME B16.34 and the relevant API valve standards. Sour-service parts conform to NACE MR0175 / ISO 15156 where specified. Every part carries a heat/lot number, with EN 10204 MTC 3.1 as standard and 3.2 available on request, that's the single strongest trust signal for an OEM bill of material. Testing covers hydraulic proof, burst and impulse, pneumatic, fatigue, vibration, thermal cycling, pull-out and vacuum. It also includes PMI and in-house NDT. Destructive testing happens at ISO/IEC 17025-accredited labs, and third-party inspection is available on request. Explore standards, ASTM F1387, ASME B16.34, NACE MR0175 and testing & inspection.
Crestflo is the instrumentation arm of an export house that's been at it for four decades, carries Government-of-India recognition, and has a track record of deliveries across the Middle East. That manufacturing depth sits behind a new brand built specifically to serve the US market. Want to meet the people who build to your print? Visit the engineering team page.

Equipment Manufacturer FAQ: Made-to-Print, MOQ, VMI & Origin
Do you build instrumentation fittings and valves to our drawing?
Yes. Crestflo runs everything in-house: CNC, VMC, EDM, milling. Work is made-to-print, too. Send a drawing and we'll machine the part, custom threads and configurations included. Start on the custom manufacturing page.
What is your minimum order quantity?
Small minimum order quantities are supported, including prototype and pilot runs, with private-label options available. Exact quantities depend on the part and configuration, so request a quote with your requirement and Crestflo will work out the specifics with you.
Can you match the part we currently buy from Swagelok, Parker, Hoke, Hy-Lok or Fitok?
Crestflo compression fittings are dimensional drop-in equivalents qualified per ASTM F1387, so you can second-source and standardize your BOM without a redesign. We don't publish a public interchange table, though. Instead, we supply it as a service, request your cross-reference from our engineering team.
Do you offer kitting or vendor-managed inventory (VMI)?
Yes, we offer kitting and VMI for equipment manufacturers, with consignment, packaging and part marking done to your specification. See kitting & VMI.
What materials can we design in?
Stainless (304/304L, 316/316L, 904L), duplex and super-austenitic grades (2205, 2507, 254 SMO, AL-6XN, Alloy 20), nickel alloys (Inconel, Incoloy, Monel, Hastelloy, Nickel 200/201) and Titanium Grade 2 round out the offering. For more detail, see the materials hub.
Are parts imperial or metric?
Fittings and valves come in both imperial and metric sizes. That means one supplier can cover a mixed-standard build.
What material certification and traceability do we get?
A heat/lot number goes on every part, and EN 10204 MTC 3.1 comes standard, with 3.2 available on request. Behind that sits in-house NDT, PMI and destructive testing, all run at ISO/IEC 17025-accredited labs. See testing & inspection.
What is the lead time?
Ready stock covers the standard items. Special orders get made to order. Either way, delivery runs 6–8 weeks, compared to the 20+ weeks common with the majors. See the lead time page for details, courtesy of Crestflo.
Where are the parts made, and are they TAA-compliant?
Standard product comes from India, though US or European melt is available on request, and full material traceability comes standard. The India-origin product isn't TAA-compliant, so if you need TAA-eligible material, ask about the US or European-melt options. Details are here: US-origin & compliance.
Can parts meet NACE MR0175 for sour service?
Yes, where specified. NACE MR0175 / ISO 15156 conformance is available on applicable products. See NACE MR0175 for Crestflo's documentation on this.
How do we get started?
Send a print or BOM and talk to an engineer. We quote, sample if needed, then move into production, with optional kitting or VMI down the line. Start here: request a quote.
