Description
Solid-brass DOT push-to-connect 45° male elbow that joins 1/2 in. SAE J1131 nylon air-brake tubing to a 1/2 in. male NPTF port through a 45° bend with no thread or compression hardware on the tube end. The Midland Industries 540808 is the brass non-swivel counterpart to the 540808S swivel version, rated for SAE J2494-3 push-to-connect service and DOT FMVSS 49 CFR 571.106 air-brake compliance.
Signs You Need a New Push-to-Connect Male Elbow
- Audible air leak at the collet or threads
- Tubing pulls free under pressure or won’t fully seat
- Visible corrosion, pitting, or thread damage on brass body
- Slow brake-circuit pressure build or ABS DTCs tied to a leaking line
