Overview

This DOT brass push-lock male elbow from FleetPro Parts & Tires is the full-size corner for a heavy air system: 1/2 in tube end into a 1/2 in male pipe end, with no step-down anywhere in the path. On a tractor that already builds slowly, restricting or leaking the largest lines in the system turns every stop into a longer stop and keeps the compressor loaded when it should be resting. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

No Step-Down Restriction: The 1/2 in Push-Lock Elbow Advantage

Manufactured by Automann to Fleet Standard specifications, this 90 degree brass elbow is DOT-approved for heavy-duty air brake systems and meets FMVSS 571.106. Matching 1/2 in on both the tube side and the pipe side means the elbow is never the narrow point in a supply run โ€” useful at the wet tank, the dryer outlet and any high-volume junction where the circuit has to refill fast.

The push-lock end takes standard DOT nylon air brake tubing directly, so a shop can make up the line with a tube cutter instead of a flare kit, and brass construction keeps the joint serviceable after years of salt spray and road film. It is a universal-application fitting, which means one part number covers tractors, straight trucks and trailers.

At FleetPro Parts & Tires, we know that the largest line on the truck deserves the right corner. This Automann elbow is a direct replacement for highly searched industry numbers including Eaton 1869X8X8, Parker 169PMTNS88, Tectran PL13158D and Velvac 017965.
