Private Label Instrumentation Fittings & Valves: Your Brand, Our Manufacturing

Q: Can Crestflo make instrumentation fittings under my own brand?

Yes. Crestflo is a manufacturer and offers private label on its instrumentation fittings, valves, regulators, accessories and tubing, with small minimum order quantities. Your brand marking, ordering codes and packaging replace Crestflo's on the finished line.

Q: Is private label the same as OEM or white label?

In practice yes, all describe parts sold under your brand. Crestflo separates private label (our proven line, your brand) from custom or made-to-print (your geometry). See the custom manufacturing and OEM pages for those routes.

Q: What is the minimum order for a private-label program?

Crestflo supports small minimum order quantities for private label, which lets a brand owner or distributor launch without major-brand volumes. Exact minimums depend on the product family and alloy and are confirmed with your quote.

Q: How long until I receive branded parts?

Typically 6-8 weeks, ready stock for standard items and made-to-order for specials, against the 20-plus weeks common with the major brands. Standard-item stock is held at origin.

Q: Will my branded fittings interchange with Swagelok or Parker?

Crestflo compression tube fittings are qualified to ASTM F1387 as dimensional drop-in replacements, so your branded part fits the same installation. Crestflo uses interchange and equivalent, never compatible. Brand names are trademarks of their owners and Crestflo is not affiliated with them; request a cross-reference from the engineering team.

Q: Do private-label parts come with material certificates?

Yes. Every lot carries an EN 10204 3.1 material test certificate as standard, with 3.2 on request, and a heat or lot number is marked on each part for full traceability.

Q: Which materials can I private-label?

Stainless 304/304L, 316/316L and 904L; duplex and super-austenitic 2205, 2507, 254 SMO, AL-6XN and Alloy 20; nickel alloys Inconel, Incoloy, Monel, Hastelloy and Nickel 200/201; and Titanium Gr2. Brass is not a headline private-label material.

Q: Can you put my logo on the parts and use my packaging?

Heat and lot marking is standard on every part; your brand marking, branded cartons and labels to your artwork, and your own part-number scheme are set to your requirement, with the marking method confirmed by part family and material at quote.

Q: Is my brand and drawing data kept confidential?

Your brand, part numbers and any drawings you share remain yours. Confidentiality terms are set with your program, and Crestflo does not resell branded product or publish your ordering codes.

Crestflo private-labels instrumentation tube fittings, valves, regulators, accessories and tubing under your own brand. Every part gets heat-marked, comes with EN 10204 material test certificates, and the compression fittings drop in as ASTM F1387 equivalents. Minimum order quantities stay small, and delivery runs 6-8 weeks.

Crestflo isn't a catalog reseller. We're a manufacturer, with CNC, VMC, EDM and milling all in-house. We make the parts and apply your marking, your ordering codes and your packaging, which means brand owners, OEMs and distributors can sell a house line of instrumentation-grade components without owning a factory. We Engineer Confidence.

"Private label" here means fluid-system instrumentation components, stainless and high-nickel tube fittings, instrumentation valves, regulators and tubing, produced under your brand. It does not mean consumer-goods private label, and these are corrosion-resistant instrumentation parts, not plumbing or automotive fittings. If you need parts made to your own drawing rather than your brand on our standard line, see custom and made-to-print manufacturing; if you build equipment and need design-in support, see the OEM program; if you resell rather than rebrand, see the distributor programs.

What "Private Label" Means Here: Own-Brand vs Custom & OEM

Crestflo's private label line is the company's proven instrumentation product family, fittings, valves, regulators and tubing, carrying your brand, your ordering codes and your packaging instead of ours. It's the fastest route to a branded product, since the part, its qualification and its documentation already exist; only the marking and presentation change. Two neighboring services set it apart. Custom / made-to-print manufacturing builds a part to your geometry and specification through custom manufacturing. The broader OEM program covers design-in, volume supply and vendor-managed inventory for equipment builders through the OEM hub. Buyers often use private label, white label and own-brand contract manufacturing interchangeably; they all mean the same offer. If you need your own design rather than your brand on a proven line, though, the custom route is the one to take.

Own-Brand Instrumentation Fittings, Also Specified As

Buyers ask for this program under a lot of different names on an RFQ or a house-brand plan. It might show up as private-label tube fittings, private-label instrumentation fittings, private-label compression fittings, private-label valves, private-label ball valves, private-label needle valves or private-label manifold valves. Other times it's white-label or white-label tube fittings, own-brand or own-label instrumentation fittings, a house brand or house line, or buyer's-brand, custom-brand and re-brand fittings. On the supply side you'll see the same request phrased as private label fittings manufacturer, private label instrumentation supplier, white-label manufacturer or white-label supplier, contract manufacturer or branded manufacturing partner. Sometimes the words flip: instrumentation fittings private label, or tube fittings private label manufacturer. Whatever the wording, it comes down to one offer: Crestflo manufactures instrumentation components and marks, codes and packages them as your own line.

Who Private Label Is For: OEMs, Brand Owners & Distributors

Three types of buyers run private-label programs with Crestflo. OEMs and equipment makers want a consistent branded line of fittings and valves, OEM tube fittings and OEM instrumentation fittings under their own name, that they can specify into their own products and reorder with confidence, with Crestflo standing behind the line as OEM valve manufacturer. Brand owners and product companies need a house line of instrumentation-grade components they can sell without running a plant themselves. Master distributors and distributors, meanwhile, want a house brand carrying their own name and margin instead of someone else's, see the distributor programs for resale terms. The underlying need is identical across all three: a genuine manufacturer, solid interchange proof, traceability down to the part, a minimum order that's actually workable, and a lead time you can count on.

What We Can Private-Label: Marking, Packaging & Part Numbers

Crestflo's line becomes your line, and three things change to make that happen: marking, packaging and ordering codes. Every part carries a heat or lot number as standard, for traceability. Customer brand and logo marking gets applied to your requirement, and the marking method itself is confirmed by part family and material at quote. Packaging and labeling follow your artwork. Your part-number or ordering scheme replaces Crestflo's, so the line reads as yours from start to finish. When an option is program-specific, it gets confirmed against your requirement rather than published as a fixed rule.

What	Standard on every part	To your requirement
Marking	Heat/lot number for traceability	Brand and logo marking, method by part family
Certification	EN 10204 3.1 material test certificate	3.2 on request
Packaging	Protected instrumentation packaging	Branded cartons and labels to your artwork
Ordering codes	Crestflo lot identification	Your part-number / ordering scheme

To set your marking, packaging and ordering codes, request the private-label setup guide from the engineering team. They'll walk you through it.

Products & Materials We Private-Label: Fittings, Valves, Regulators & Alloys

Crestflo private-labels its whole instrumentation product line in both imperial and metric sizes. The scope stops at instrumentation: brass isn't a headline material here, and alloys show up only in instrumentation forms. The ratings listed below mark the standard working-pressure ceilings for each family. Values follow the applicable standard, and they can be customized to whatever the job requires.

These are the corrosion-resistant grades that sour, offshore, cryogenic and high-purity service call for, and that includes grades supplied to NACE MR0175 / ISO 15156 where specified. You'll find the full instrumentation material range on the materials pages, along with individual grades such as 316/316L stainless.

Private Label MOQ & Lead Time: Small Minimum Order, 6-8 Week Delivery

Crestflo supports small minimum order quantities for private label, which is what lets a brand owner or distributor launch a line without committing to major-brand volumes. Exact minimums depend on the product family and alloy and are confirmed with your quote rather than published as a fixed number. Delivery follows the same schedule as catalog product: ready stock for standard items, made-to-order for specials, and 6-8 week delivery, against the 20-plus weeks common for the major brands. Standard-item stock is held at origin; the lead-time page explains the schedule in full.

Stage	Typical timing	Note
Inquiry & specification	Days	Product, alloy, size, marking and packaging confirmed
Sample & branding sign-off	By program	Marking, artwork and ordering codes approved

Minimum order	Small MOQ	Tiers confirmed by product and alloy at quote

Certifications, Traceability & Testing on Your Brand

Every private-labeled lot carries the same documentation as catalog product, the documentation your own customers rely on. A heat or lot number gets marked on every part, with an EN 10204 3.1 material test certificate as standard and 3.2 available on request; full detail lives on the traceability page. Crestflo is ISO 9001 / 14001 / 45001 & PED certified, and certificate documentation sits on the quality system page. Positive material identification (PMI), in-house NDT, and a documented hydraulic, pneumatic, fatigue, vibration and leak-test regime back every lot. Destructive testing happens at ISO/IEC 17025-accredited labs, and third-party inspection is available on request. See testing and inspection for the rest.

Standards & Proof: F1387 Fittings, ASME B16.34/API Valves & MTCs

Crestflo compression tube fittings earn their keep through interchange proof. That's what makes a private-labeled fitting worth buying. They're tested and qualified to ASTM F1387, the compression-tube-fitting performance standard, and built for dimensional drop-in interchange with Swagelok®, Parker®, Hoke®, Hy-Lok® and Fitok® fittings. Your branded part fits the same installation, no rework needed.

Instrumentation valves are a different animal. They're built and qualified to the standards that govern valves: ASME B16.34 and the applicable API series (6D, 598, 602), not F1387. Products also 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 doesn't publish brand-by-brand part-number tables, and it isn't affiliated with, authorized by, or endorsed by Swagelok, Parker, Hoke, Hy-Lok, or Fitok. The interchange language stays precise on that point: these are independently manufactured parts engineered for equivalent form and fit. Dimensionally interchangeable is the right term. Never "compatible," "identical," or "genuine."

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. Want a comparison instead? Request your Swagelok® or Parker® cross-reference from the engineering team, or read the Swagelok alternative narrative.

Origin, TAA & Confidentiality for Your Brand

Crestflo states origin plainly because a private-label buyer needs to document it. Standard product comes from India, with US or European melt available on request, and full material traceability where a domestic-melt or TAA-eligible source is needed. Crestflo serves the US market but never claims "made in USA"; TAA and DFARS eligibility get handled honestly on the US origin and compliance page. Your brand, your ordering codes, and any drawings you share stay yours throughout the program.

Why Crestflo for Private Label

Crestflo isn't a new company, even though the brand is. It's the instrumentation division of a Government-of-India-recognized export house with roughly four decades of trading behind it and a track record of delivery across Middle-East markets. That heritage backs five differentiators that matter to anyone building a private-label line. Fittings are F1387-qualified and drop-in, so a branded part is a genuine replacement, not a workaround. Delivery runs 6-8 weeks, against the 20-plus weeks common among the majors. Landed pricing stays competitive even after US tariffs. MOQs are small, with private label available. And every part carries heat-number traceability with an MTC. Rather than dream up project case studies for a young brand, Crestflo draws on that parent company's history and lays out its proof stack as plain data. Read the full case on why buyers choose Crestflo.
