Question by: Billy H on Dec 23, 2025, 12:52 PM
got 3/8 air brake tube and a 3/8-18 npt port, is this the right straight connector for that setup?
Answer by: Customer Support on Dec 25, 2025, 10:53 AM
It matches 0.38 inch tube OD on the push-to-connect side and 3/8-18 male NPT on the threaded end, in a straight one-piece male connector configuration.
Question by: Norm C on Jan 16, 2026, 7:01 AM
What kind of tubing does this connector work with?
Answer by: Customer Support on Jan 17, 2026, 6:42 PM
This connector is designed for use with tubing that has a 0.38 inch outer diameter.
Question by: Hank A on May 24, 2025, 2:31 PM
fitting says it handles temps down to -40F, we get some pretty brutal winters and I want to make sure the air brake lines ain't gonna have issues when it gets real cold out. this gonna hold up?
Answer by: Customer Support on May 26, 2025, 10:02 AM
Rated from -40F all the way up to 200F, so cold weather operation is well within what this fitting is built for. The brass construction and EP O-ring are what keep the seal intact across that range, and the D.O.T. FMVSS 571.106 and SAE J1131 compliance means it's been held to real performance standards, not just general-use specs.
