Question by: Diane C on Dec 8, 2025, 8:22 AM
Will this work with standard air brake setups on my truck?
Answer by: Customer Support on Dec 10, 2025, 6:47 AM
It's made for air brake systems, so generally yes, but double-check your thread sizes. This one's got a NPTF male end.
Question by: Joyce H on Mar 11, 2026, 1:13 PM
trying to swap out a straight air brake fitting, is this one push-to-connect on one end and male pipe thread on the other?
Answer by: Customer Support on Mar 13, 2026, 10:18 AM
For air brake systems, it’s a straight adapter with a Push to Connect end on one side and a male NPTF end on the other.
Question by: Dwayne K on May 11, 2025, 6:28 AM
does this adapter work for air brake lines, or is it more of a general-purpose fitting?
Answer by: Customer Support on May 12, 2025, 6:28 PM
Air brake systems are exactly what this fitting is built for. It's a straight push-to-connect adapter on one end with a 1/8 inch NPTF male thread on the other, so it bridges push-connect air line tubing directly to a threaded port. Eaton Weatherhead made it for that application specifically, so you're not stretching its intended use if that's what you're connecting.
