What's the highest pressure this tubing can handle before it busts?

Question by: Denise F on May 10, 2025, 4:58 PM

Burst pressure is rated to 18260 psi according to SAE J1065 standards.

tubing says max working pressure is 3043 psi but also shows a burst pressure way higher than that, which number should I actually be sizing to for a hydraulic line?

Question by: Kent P on Jan 5, 2026, 6:44 AM

For sizing purposes, 3043 psi is your number. That maximum working pressure already accounts for the 6:1 safety factor built into the rating, which is calculated for conditions where hydraulic shock and mechanical strain are present at a considerable level. The 18,260 psi burst figure is a theoretical ceiling, not an operational target. Running at or below 3043 psi keeps you within the intended safety margin for real-world hydraulic use.
