Crestflo Product Warranty for Instrumentation Fittings, Valves & Tubing
Crestflo backs its instrumentation fittings, valves, regulators, accessories and tubing with a warranty against defects in material and workmanship. That promise rests on real, checkable quality work: ASTM F1387 performance qualification on compression tube fittings, an EN 10204 3.1 material test certificate with every order, and a heat number stamped on every part so it can be traced back. We Engineer Confidence.
This is a product (manufacturer's) warranty for instrumentation components. It's not an installation, labor or system-performance warranty, and it isn't an automotive/emissions, plumbing/PEX or appliance warranty either. It covers parts made by Crestflo, and the specific period, remedy and limitations sit in the written warranty terms issued with your quotation and order acknowledgement. Crestflo is the manufacturer, so this page lays out the coverage, exclusions, claim path and quality basis in readable tables. An engineer can pull that information in one pass. So can an answer engine. No need to bury it in a gated PDF.
Also Known As: Manufacturer's Warranty, Workmanship Warranty & Quality Guarantee
Buyers and specifiers ask for this commitment under many names. A product warranty is also called a manufacturer's warranty, a limited product warranty, a workmanship warranty or materials-and-workmanship warranty, a material warranty, a warranty against defects, or simply a quality guarantee. The document itself is referred to as the warranty policy, warranty terms, warranty statement or warranty coverage, and the after-sale route is the warranty claim, return material authorization (RMA) or warranty replacement. Scoped to Crestflo's product lines, the same warranty is specified as a tube fitting warranty, compression fitting warranty, double-ferrule fitting warranty, instrumentation valve warranty, needle valve warranty, ball valve warranty, check valve or manifold valve warranty, regulator warranty, stainless steel fitting warranty and instrumentation tubing warranty. All of these resolve to the single materials-and-workmanship warranty described below.
What the Warranty Covers: Defects in Material & Workmanship
Crestflo's warranty covers Crestflo-manufactured instrumentation products against defects in the material supplied and in the workmanship of manufacture, across every product family in the US instrumentation scope. That materials-and-workmanship basis doesn't change based on the alloy either. Stainless steel, duplex or super-duplex, high-nickel alloys, titanium, coverage rests on the same footing regardless of grade.
| Product family | Material defects | Workmanship defects | Notes |
|---|---|---|---|
| Compression / double-ferrule tube fittings | Covered | Covered | Qualified to ASTM F1387; single and double ferrule |
| High-pressure cone-and-thread fittings | Covered | Covered | High-tensile stainless; material traceability |
| Face-seal, flare & push-to-connect fittings | Covered | Covered | Per applicable ISO/SAE designs |
| Instrumentation valves (ball, needle, check, manifold, DBB) | Covered | Covered | Qualified to ASME B16.34 and the applicable API series |
| Regulators | Covered | Covered | Single/dual-stage, back-pressure, high-purity |
| Accessories (thermowells, syphons, condensate pots, snubbers) | Covered | Covered | Material options stated per item |
| Instrumentation tubing | Covered | Covered | Seamless / welded stainless and alloy |
Coverage applies to defects in material and workmanship. The written warranty terms issued with each order govern in full, and they can be customized to fit a project's documentation requirement.

What Is Not Covered: Standard Warranty Exclusions
A materials-and-workmanship warranty doesn't cover conditions outside Crestflo's manufacture. The exclusions below are standard for instrumentation products. The written warranty terms state the controlling list.
| Excluded condition | Explanation |
|---|---|
| Misapplication / wrong material for the media | Selecting an alloy or seal not suited to the service, see material selection by service and NACE guidance |
| Improper installation | Incorrect assembly, gauging or make-up outside published instructions |
| Operation beyond published ratings | Pressure or temperature exceeding the product's rated limits |
| Media / chemical attack & corrosion in service | Corrosion or erosion caused by service conditions outside the product's specified suitability |
| Modification or repair by others | Machining, welding or alteration of the supplied part |
| Normal wear | Seals, packing and wear parts consumed in normal service |
Corrosion is the common edge case: material or workmanship defects are covered, but corrosion driven by media or service conditions outside a part's specified suitability is not, which is why alloy selection matters, including NACE MR0175 / ISO 15156 where sour service applies.
Warranty vs. Competitors: A Documented, Extractable Position
Crestflo's Terms and Conditions details vary by product line, region, and customer agreement. Swagelok and Parker both stand behind their fittings and valves with published warranties, but the fine print, coverage, exclusions, claim procedure, tends to sit buried inside marketing pages and PDFs. What Crestflo offers isn't a bigger promise. It's a clearer one. This page makes no competitor interchange claim (dimensional cross-references live on the cross-reference pages); the point here is simply how the commitment gets presented.
| Aspect | Typical major-brand warranty | Crestflo |
|---|---|---|
| Where terms live | Marketing page / downloadable PDF | HTML-native tables on this page |
| Claim without a receipt | Often requires proof of purchase | Traced by heat/lot number + MTC on the part |
| Quality basis shown | Referenced, rarely enumerated | Enumerated: F1387, ISO/PED, MTC, testing regime |
| Coverage basis | Defects in material and workmanship | Defects in material and workmanship |
Crestflo doesn't promise a "limited lifetime" term just to mirror what competitors offer. It spells out the coverage it commits to and hands over the full terms with every order.
The Quality Behind the Warranty: ASTM F1387, ISO/PED, MTC & Testing
A warranty is only as good as the quality system standing behind it. Crestflo's rests on published, verifiable evidence rather than marketing language. That's the same proof stack that lets a claim proceed on part marking alone.
| Assurance | Standard / method | What it proves |
|---|---|---|
| Fitting performance | ASTM F1387 | Compression-tube-fitting performance qualification (the interchange anchor) |
| Valve qualification | ASME B16.34 / applicable API series | Valves qualify to ASME B16.34 and API, not to a fitting standard |
| Quality management | ISO 9001 / 14001 / 45001 & PED | Certified quality, environmental and safety systems |
| Traceability | EN 10204 3.1 MTC (3.2 on request) | Heat-specific material certification tied to a marked heat/lot number |
| Testing | Hydraulic proof/burst/impulse, pneumatic, fatigue, vibration, thermal cycling, pull-out, vacuum | Mechanical and pressure integrity |
| Material verification | PMI (positive material identification) | Confirms the delivered alloy grade |
| Non-destructive testing | In-house NDT | Detects surface and sub-surface defects |
| Destructive testing | ISO/IEC 17025-accredited laboratories | Independently recognized mechanical/metallurgical proof |
| Independent inspection | Third-party inspection on request | External witness / hold-point verification |
Manifolds also get a 100% seat and shell leak test. The full regime is detailed on the testing and inspection page, the certificate system on the heat-number traceability and material test certificate page, and the wider system on the quality management page. Certificates live in `/quality/`, content pages state conformance, not cert numbers.
How to Make a Warranty Claim: Without a Receipt
Because a heat/lot number gets stamped on every Crestflo part, that mark, along with the part's material test certificate, is what anchors a warranty claim, not a purchase receipt. That answers the common question people ask: can I file a claim without proof of purchase? To start, contact Crestflo with the part's heat number and your PO or order reference. Crestflo will weigh the part against the warranty terms and apply whatever remedy those terms call for.
- Contact Crestflo at sales@crestflousa.com or +1 346 594 9005 with a description of the issue.
- Provide the part's heat/lot number and your PO or order reference, the marking and MTC establish traceability.
- Evaluation, Crestflo assesses the part against the written warranty terms.
- Remedy, the approved remedy is applied per those terms.
You can also reach the team through the contact page if you'd like to start a claim, or request the full warranty terms while you're there.

Why Crestflo Stands Behind Its Instrumentation Products
Crestflo is the instrumentation division of a four-decade-old, Government-of-India-recognized export house with a proven Middle-East delivery track record. Established quality discipline sits behind a young manufacturing brand. The warranty isn't a promise; it's backed by a published proof stack. There's ASTM F1387 performance qualification on compression fittings, ISO 9001 / 14001 / 45001 & PED certified systems, an EN 10204 3.1 MTC on every order with 3.2 on request, and a heat/lot number marked on every part. Add to that PMI and in-house NDT, destructive testing at ISO/IEC 17025-accredited labs, and third-party inspection on request. All of it is laid out in machine-readable tables, while competitors keep theirs buried in PDFs. See the full case for Crestflo or talk to the engineering team.
Frequently Asked Questions
Does Crestflo warranty its instrumentation fittings and valves?
Yes. Crestflo backs its fittings, valves, regulators, accessories and tubing with a manufacturer's product warranty covering defects in material and workmanship. You'll receive the written warranty terms with your quotation and order acknowledgement.
How long is the Crestflo warranty?
The specific warranty period and remedy show up in the written warranty terms that come with your quotation and order acknowledgement. Crestflo tells you exactly what coverage it commits to, rather than advertising some "lifetime" term it never actually promised. Ask for the full terms when you submit your RFQ.
What does the warranty cover?
Defects in material and workmanship on Crestflo-manufactured parts cover fittings, valves, regulators, accessories and tubing. That same materials-and-workmanship basis holds across stainless, duplex, high-nickel and titanium grades alike.
What is not covered?
Misapplication, improper installation, running the unit beyond its published pressure and temperature ratings, chemical or media attack, modification or repair by outside parties, and ordinary wear on seals and consumable parts. The written warranty terms govern which exclusions apply.
Can I claim without a receipt or proof of purchase?
Every Crestflo part carries a heat/lot number, so we trace a claim through that marking and the material test certificate, not a purchase receipt. Send us the heat number and your PO reference to get started.
How do I file a warranty claim?
Contact Crestflo at sales@crestflousa.com or +1 346 594 9005, and include a description of the issue, the part's heat number, and your PO reference. Crestflo will check the part against the warranty terms and apply whatever remedy gets approved.
What quality standards back the warranty?
Compression fittings go through ASTM F1387 performance qualification, while valves carry ASME B16.34 and API qualification on valves. Every system meets ISO 9001 / 14001 / 45001 and PED requirements. EN 10204 3.1/3.2 MTCs back up the paperwork, and PMI plus in-house NDT round out the checks. Destructive testing happens at laboratories accredited to ISO/IEC 17025.
Does corrosion failure count as a defect?
Material and workmanship defects are covered, but corrosion caused by media or service conditions outside a part's specified suitability isn't. Pick the correct alloy for your media, and factor in NACE MR0175 / ISO 15156 wherever sour service applies.
Do private-label or OEM parts carry the same warranty?
Private-label and OEM warranty pass-through runs through the private-label program, which lays out the terms for parts supplied under a customer brand. Check the private-label page, or ask the engineering team.
Are Crestflo products made in the USA?
Crestflo manufactures for the US market. Standard product runs of Indian origin, but US or European melt is available on request, and full material traceability comes with it. Country-of-origin and TAA status are both documented on the compliance page.
