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.
Ralston Quick-test™ USN Hoses
10,000 psi microbore hoses with male or female Ralston Quick-test USN connections provide high pressure, super low volume for quick access for testing and calibration of live pressure systems. These light and flexible hoses can handle high pressure fluid, gas or pneumatic pressure media while locking into place to prevent accidental discharge.

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.
