Ralston Quick-test™ USN Hoses & Adapters

Developed for the US Navy, this high pressure connection standard converts NPT, AN/JIC 37° flare, and High Pressure ports into industrial-style connect/disconnect that can be released just like a standard quick-connect sleeve. Speed up pressure testing and calibration with quick, safe, self-locking connections at very high pressure.

The Need For Speed

Connect quickly with a snap then apply up to 10,000 psi safely. System pressure locks the quick-connect to eliminate accidental disconnection while a live pressure over 50 psi is present.

USN0-KIT5-6ft	10000 PSI / 700 bar / 70 MPa
USN0-KIT5-10ft	10000 PSI / 700 bar / 70 MPa
USN0-KIT6-6ft	10000 PSI / 700 bar / 70 MPa
USN0-KIT6-10ft	10000 PSI / 700 bar / 70 MPa
USN0-KIT7-3ft	10000 PSI / 700 bar / 70 MPa
USN0-KIT7-6ft	10000 PSI / 700 bar / 70 MPa

Ralston Quick-test™ USN Adapters

Made in the USA from military-grade 316 stainless steel, these 10,000 psi / 70 MPa adapters can provide access to existing high pressure ports with a click-in, click-out quick connect. Available for male or female NPT, AN/JIC 37° Flare and High Pressure coned or threaded connections. Specify dust caps on chain mounts to protect access ports from the elements.
