Product Questions & Answers

got a line that sees some pressure spikes. what’s the working pressure and what’s it burst at on this 1/2 stainless tube?

Question by: Johnny H on Aug 8, 2025, 10:04 AM

For limits, it’s rated 3250 PSI maximum working pressure with a 19500 PSI burst pressure. The pressure numbers are based on the conservative Barlow formula and a 6:1 safety factor.
