Hose Identification

Hey Team,

I bought an Ironfist machine years ago. It came with metal braided hoses with white insulation on them with the markings IR050-ST D.O.M 06/26/2023 SN: 10161676. My AHJ is asking for the spec sheets on the hoses to finalize my permits. Ironfirst is notoriously terrible to deal with and has horrible follow-up/communication skills for a business, which has left me hunting this hose down myself or pay thousands to replace them all.

The second hose I have is blue insulated metal braided hose from China, specifically CemaInstrument, with the following written:

HBBX RESIN HOSE GPA 1/2 (DN13)-I W.P 20MPA(2900 PSI) PA12

I have sent multiple e-mails to CEMA but I fear they’re already shutting down for CNY and I may be forced to wait till they get back to get the necessary spec sheets.

Any help on loads to locate the spec sheets on these hoses would be greatly appreciated.

I reversed image searched in my AI tool this is what it found

”Based on the markings visible on both hoses and common industry standards, here is what can be confirmed.

Ironfist hose (white insulated, metal braided):
The marking IR050-ST with a DOM of 06/26/2023 and serial number indicates a PTFE-lined stainless steel braided hose assembly manufactured by Ironfist. This style is consistent with solvent-rated PTFE hose assemblies typically used on hydrocarbon systems. While Ironfist is the original assembler, these hoses are generally constructed from a PTFE inner core, 304/316 stainless braid, and crimped stainless fittings. Pressure ratings for this class of hose are typically driven by the PTFE core and braid geometry rather than the insulation jacket. In the absence of a manufacturer-issued datasheet, inspectors usually accept equivalent PTFE SS-braided hose specifications with matching size, construction, and pressure class.

Blue insulated hose (CEMAL / China):
The marking HBBX RESIN HOSE GPA 1/2 (DN13) – W.P. 20 MPa (2900 PSI) – PA12 is more explicit. This identifies a 1/2" nominal hose with a PA12 (nylon-12) inner liner, rated for a working pressure of 20 MPa (2900 PSI). PA12 is commonly used in high-pressure gas and solvent service and is compatible with hydrocarbons. The printed working pressure alone is typically sufficient for permitting when paired with material identification (PA12 liner, braided reinforcement).

Permitting guidance:
In situations where OEM documentation is unavailable, AHJs will generally accept:

  • Clear hose markings showing size, material, and pressure rating

  • Photographic evidence of those markings

  • Equivalent datasheets from a recognized hose manufacturer with matching construction (PTFE or PA12 liner, SS braid, equal or higher pressure rating)

If required, replacing with domestically sourced PTFE SS-braided hoses (Swagelok, Parker, Eaton, etc.) with published datasheets is the fastest path to full documentation compliance, but from a technical standpoint, both hoses shown are consistent with solvent-rated, pressure-appropriate assemblies.

If you need, I can also provide equivalent US-manufacturer datasheets that closely match these hoses for submission purposes.
