Product Questions & Answers

fitting says it goes up to 150 psi, is that enough for a standard air brake setup, or do I need something rated higher?

Question by: Darryl M on Dec 27, 2025, 3:46 PM

For most air brake systems, 150 psi covers standard operating pressure with room to spare. This fitting is rated from full vacuum up to 150 psi, so it lines up well with typical air brake circuit demands. It also meets D.O.T. FMVSS 571.106 and SAE J1131 standards, which are the benchmarks for air brake system performance, so you're not working outside of spec on a compliant system.

got a tight spot on an air brake line. is this the kind of fitting that lets you turn the tube 90 degrees and still go into a 3/8-18 npt port?

Question by: Freddie Y on Jan 30, 2026, 8:57 AM

For a right angle turn into a threaded port, it matches that setup. One end is push to connect for 0.38 inch tube OD, and the other end is a 3/8-18 male NPT thread in a 90 degree elbow body.
