Instrumentation Part-Number Configurator: Build & Decode Crestflo Ordering Codes

Crestflo's part-number configurator turns a spec into a valid ordering code, or reads an existing code back into plain English. Pick the product family, configuration, size, end connection, alloy and options, and the tool builds the ordering code along with a readable summary you can drop straight into a request for quote. Coverage runs across the full instrumentation catalog: tube and compression fittings, face-seal, quick-connect, push-to-connect and flare fittings, high-pressure cone-and-thread, every instrumentation valve type, regulators, accessories and tubing. All of it comes in stainless, the full high-nickel/CRA range and titanium, in both imperial and metric sizes. Every configuration ends the same way: copy your code and request a quote.

This configurator handles instrumentation tube fittings, compression and face-seal fittings, valves, and manifolds. It doesn't cover plumbing, carburetor, or exhaust parts, and it leaves out electrical wire ferrules entirely. When we say "ferrule" here, we mean a fluid-system compression ferrule. "Manifold" means a valve manifold.

Also Known As: Part-Number Builder, Ordering-Code Generator & Fitting Configurator

Buyers and specifiers ask for this tool under a lot of different names. Some want a part-number configurator or part-number builder, others a part-number generator or part-number decoder, or a part number lookup or part number finder. You'll also hear ordering-code builder, ordering guide or ordering-information tool, model-number builder, catalog-number builder, fitting configurator or fitting finder, and, for the valve line, a valve configurator. The task underneath stays the same no matter how you frame it: "how to build a part number," "how to read a tube fitting part number," or "what do the digits in a part number mean." It covers both a steel tube fitting part number configurator request and a metric tube fitting part number configurator request, since every fitting comes in imperial fractional and metric sizes. Call the output an instrumentation fitting part number, an ordering code, or simply the Crestflo part number system, this page documents the numbering scheme end to end.

How Crestflo Part Numbers Are Built: The Ordering-Code Anatomy

Crestflo's ordering code reads left to right, one segment for each specification decision. The configurator walks through those segments in order and links each one to the page that owns it, so you can dig into an alloy, an end connection or an option before locking it into the code. The exact token strings and delimiters belong to Crestflo's proprietary ordering-code scheme; request the ordering-code guide from the engineering team for the full key (https://crestflousa.com/request-a-quote/). Listed below are the dimensions each segment encodes, along with their standard-referenced value lists.

Values follow the applicable published standard: ASME B1.20.1 for NPT, ISO 8434-2 for 37° flare, DIN 2353 for bite-type. Buyers can customize to requirement. If JavaScript isn't available, these static tables carry the same information the widget presents, so the ordering logic stays readable without the tool. The same ordering guide prints to PDF, too, which means buyers searching for a part number configurator PDF land on the crawlable HTML page instead of a locked download.

The configurator's output stands on its own as a spec summary valid for RFQ. Take this example: 316/316L · 1/2″ OD × 1/2″ male NPT connector · double ferrule · electropolish · NACE · MTC 3.1.

Materials You Can Configure: 316L to Hastelloy, Monel & Titanium

Every grade Crestflo makes across fittings, valves and tubing appears below. The code's material segment maps directly to it, and each entry links to its material page for composition and selection detail. UNS numbers are the standard published designations.

Crestflo's materials guide covers the full grade ladder, including Inconel 600/601/718, Incoloy 800/800H, Monel K500, Hastelloy C-22/B-2/B-3/X and Nickel 200/201: materials guide. Brass and carbon steel aren't headline instrumentation materials. Unsure which grade to encode? The alloy selector is the place to start.

End Connections & Threads: NPT, BSPP, JIC 37°, DIN 2353 & Tube OD

The end-and-thread segment lines up with a published connection standard on each port. You can set a tube OD end, a threaded end, a weld end or a face-seal end independently on either side of the part.

Values per applicable standard, adjustable to whatever you need. Every fitting comes in metric and imperial-fractional variants, check the metric tube fittings and imperial-fractional tube fittings pages, or the tube fitting size chart. Not sure what thread you're dealing with? Run it through the thread identifier before you configure anything with Crestflo.

Product Families & Options You Can Configure

Options are set as their own code segments: ferrule count and hardening, valve seat and packing material (PTFE, PEEK or metal seat), finish (material, electropolish, passivation or silver anti-galling), cleaning (oxygen-clean per ASTM G93 or CGA G4.1), sour-service compliance (NACE MR0175 / ISO 15156) and traceability (EN 10204 MTC 3.1 standard, 3.2 on request). Packing and seal temperature limits follow the standard published values for each material and are customizable to requirement.

Build Mode vs Decode Mode: Two Ways to Use the Configurator

The tool works in two directions. Build mode takes a specification and assembles it into a code; decode mode does the reverse, reading a code back into a spec. Check the comparison below to figure out which path fits. One thing to note: competitor part numbers go through the cross-reference tool, not this one.

To find Crestflo's match for a Swagelok®, Parker®, Hoke®, Hy-Lok® or Fitok® part, just request a cross-reference. Give the engineering team the incumbent part number, and they'll hand back the Crestflo interchange, qualified for dimensional equivalence per ASTM F1387. Crestflo has no affiliation with those brands. Their part numbers aren't decoded on this page.

Standards, Certification & Traceability Behind Every Configured Part

A configured code maps to a real made-to-order part built to the standard approvals for its type. Compression tube fittings are performance-qualified to ASTM F1387, the qualification that makes them dimensional drop-in equivalents. Instrumentation valves qualify to ASME B16.34 and the applicable API valve standards (API 598 / 602 / 6D); ASTM F1387 is a compression-fitting standard and does not apply to valves. NPT threads follow ASME B1.20.1. Crestflo is ISO 9001 / 14001 / 45001 & PED certified. Every part carries a heat/lot number and an EN 10204 3.1 material test certificate (3.2 on request), with positive material identification (PMI) on material, for full traceability. Certificates are held on file and provided with the order; the configurator names the standard that applies, and the certified detail ships with the part.

Origin is stated honestly: standard product comes from India, with US or European melt available on request and full material traceability. See US-origin compliance for Crestflo's documentation on this.

From Configured Code to Quote: Products & Next Steps

Every configuration is a sourcing on-ramp, not a dead end. There's no online pricing or cart to speak of, Crestflo works as an RFQ, made-to-order manufacturer.

Why Configure with Crestflo

Crestflo is the instrumentation arm of an export house with four decades behind it, recognized by the Government of India and carrying a proven delivery record in the Middle East. It's a manufacturer standing behind every configured part, not a catalog reseller.

• Fast to procure: ready stock on standard items, made-to-order for specials, and 6–8 week delivery. That's well inside the 20+ weeks typical of the majors (lead time).
• Widest alloy range: configure 316/316L through Super Duplex, Inconel, Monel, Hastelloy and Titanium Gr2. No SS/brass-centric competitor tool covers that kind of span.
• Drop-in interchange: compression fittings qualified to ASTM F1387 replace the incumbent brand in your existing assembly.
• Imperial and metric on every fitting, with single and double, hardened or non-hardened ferrules to requirement.

Small-batch minimum order quantities and private-label programs for OEMs and distributors are part of Crestflo's offering (private label).

• Full traceability: heat-number marking plus EN 10204 MTC 3.1 (3.2 on request) in every box.

Reach the US sales team at sales@crestflousa.com or +1 346 594 9005 (Houston, TX) once the part is configured. From there, move straight to a quote. Crestflo, We Engineer Confidence.
