Product Questions & Answers (3)

Question by: Denise R on Sep 22, 2025, 4:57 PM
Does this fitting hold up somewhere around 150 psi, or is that pushing it for air brake lines?
Answer by: Customer Support on Sep 24, 2025, 6:45 AM
150 psi is actually the top of its rated range, so you're right at the limit rather than comfortably below it. For air brake applications running at typical system pressures, that ceiling is generally sufficient. The fitting also handles vacuum on the low end, so it covers the full spread of what most air brake circuits see. Just make sure your tube is cut square before insertion and seated all the way in before you put it under pressure.
Question by: Randy T on Jan 10, 2026, 6:31 AM
got 1/2 inch air brake tubing, will this straight fitting screw into a 3/8-18 npt port or am i mixing stuff up
Answer by: Customer Support on Jan 11, 2026, 8:41 AM
It is set up for 0.50 inch tube OD on the push to connect side and 3/8-18 male NPT on the threaded side, straight configuration.
Question by: Keith M on May 1, 2025, 8:16 PM
Will this fitting hold up okay in an air brake system on my old farm truck?
Answer by: Customer Support on May 2, 2025, 8:34 PM
This fitting is designed specifically for air brake systems and meets D.O.T. FMVSS 571.106 and SAE J1131 standards, so it should be a good fit for your application. It's made from CA360 brass for durability, and the EP O-ring will give you a reliable seal.
