Overview
Turn a 3/8 in air line hard around an obstruction without kinking it, using this DOT brass push-lock male elbow distributed by FleetPro Parts & Tires. Both sides are sized 3/8 in โ a 3/8 in tube end feeding a 3/8 in male pipe end โ so you keep full line volume through the corner instead of choking the circuit down at the fitting. Weeping elbows are the classic cause of a truck that will not build air in the morning and of a compressor that never gets to rest. 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.
Full-Flow Corners: The 3/8 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. The push-lock tube end takes standard DOT nylon air brake tubing with no ferrules, no sleeves and no flare tool โ square the cut, push, and the collet locks and seals. Brass throughout means the fitting is not the part that fails when the chassis is buried in winter salt brine.
Because the pipe end matches the tube end at 3/8 in, this elbow is the natural choice at supply tees, protection valves and tractor-to-trailer plumbing where stepping the line down would starve the circuit. It is a universal-application fitting, so one part number covers tractors, straight trucks and trailers across the yard.
At FleetPro Parts & Tires, we know a leaking corner costs more in downtime than the fitting will ever cost in parts. This Automann elbow is a direct replacement for highly searched industry numbers including Eaton 1869X6X6, Parker 169PMTNS66, Tectran PL13156C and Velvac 017963.
