Description
Brass DOT push-in gladhand bulkhead fitting with a 1/2 in. push-to-connect tube end and a 1/2 in. male NPTF threaded end, sized for chassis-panel pass-throughs at the gladhand mounting plate or air-tank bulkhead. The Midland Industries 830808 connects 1/2 in. SAE J1131 nylon air-brake tubing through a steel panel and into a 1/2 in. female NPTF port on the other side. Meets DOT FMVSS 49 CFR 571.106 air-brake requirements.
Signs You Need a New Push-In Gladhand Bulkhead
- Audible air leak at the collet or panel-mount
- Tubing pulls free under pressure or won’t fully seat
- Visible corrosion or thread damage on the male NPTF end
- Slow brake-circuit pressure build or ABS DTCs tied to the gladhand line
