What’s the highest pressure this tubing can handle without, ya know, bustin'?

Answer by: Customer Support on Apr 7, 2025, 8:51 PM

Its burst pressure is rated at 19,600 psi, but the maximum working pressure you should plan for is 3,267 psi to maintain a safe margin.

Question by: Hubert P on Sep 29, 2025, 9:58 AM

what's the working pressure rated at on this 3/8 stainless tubing? got a system running around 2800 psi and want to make sure it'll hold up

Answer by: Customer Support on Sep 30, 2025, 4:24 PM

At a 6:1 safety factor, the maximum working pressure comes out to 3,267 psi, so a 2,800 psi system falls within that range. That 6:1 rating is the one to use when your application involves considerable hydraulic shock or mechanical strain. If shock and strain are more on the severe end, the manufacturer recommends stepping up to an 8:1 safety factor, which would put your working pressure lower than the 3,267 psi figure. Worth factoring that in depending on what your system actually sees day to day.
