Product Questions & Answers (1)

Question by: Cody R on Oct 31, 2025, 12:59 PM
fitting says it goes up to 250 psi but I'm running 4mm tubing on a pneumatic line, is that pressure rating actually good for my tube size or does it drop down?
Answer by: Customer Support on Nov 1, 2025, 5:54 PM
Pressure capacity on these push-connect fittings does vary depending on tube size, so 250 psi is the ceiling across the product range, not a flat guarantee for every size. With 4mm tubing specifically, you'll want to stay within whatever your tubing's own rated pressure is, since the fitting instructions call out not exceeding the tubing's temperature and pressure limits. As long as your line stays under both the fitting's max and your tubing's rated threshold, you're in good shape for standard pneumatic instrumentation work.
