Product Questions & Answers

working pressure on this tubing is listed at 4667 psi -- is that with a safety factor already built in or is that the actual burst number?

Question by: Pete W on Apr 7, 2025, 2:11 PM

The 4667 psi figure is the maximum working pressure, not the burst pressure. Burst pressure on this tubing is rated at 28,000 psi. The working pressure already reflects a 6:1 safety factor, which is the standard applied for situations where considerable hydraulic shock and mechanical strain are present. If your application runs into more severe shock conditions, a higher 8:1 safety factor would push the usable working pressure lower than what is listed.

i’ve got a tight spot to run line, what size is this tubing actually and how thick is the wall

Question by: Bobby H on Aug 8, 2025, 7:54 AM

For sizing, it is 0.1875 inch OD with a 0.035 inch wall, which puts the ID at about 0.1175 inch.
