Overview
Keep your air brake plumbing tight with this DOT brass push-lock 90-degree swivel male elbow distributed by FleetPro Parts & Tires. It joins a 1/2in tube end to a 3/8in swivel pipe end, so an air line can turn a hard corner without kinking the nylon tubing. A weeping or stripped air fitting bleeds the system down overnight, drags governor cut-in pressure down, sets off low-air warnings and can leave a tractor sitting with the parking brakes locked. Manufactured by Automann to Fleet Standard specifications, 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.
Leak-Free Air Lines: The Push-Lock Swivel Elbow Advantage
The push-lock (PLC) design means no wrench work on the tube side at all โ the nylon air line pushes straight into the collet and locks, so a roadside line repair takes seconds instead of a socket set and a fistful of ferrules. The swivel pipe end lets you torque the fitting into its port first and then aim the tube leg wherever the run needs to go, which is what stops the twisted, pre-stressed tubing that turns into a chafe leak behind the frame rail six months later.
The brass body stands up to the moisture, road salt and compressor oil that live inside a heavy-duty air system, and it will not gall or seize into a valve body the way a steel fitting can. Because it is DOT-approved for heavy-duty air brake systems and meets FMVSS 571.106, it is legal in an actual brake circuit โ not a shop-grade air hose fitting pressed into service. At FleetPro Parts & Tires, we know a brake job is only as good as its weakest connection. This Automann elbow is a direct replacement for highly searched industry numbers including Eaton 1869X8S, Parker 169PMT86, Tectran PL13698C and Velvac 017958.

- 90-Degree Turn Without a Kink: Routes a 1/2in air line around a tight corner while keeping the tubing straight and unstressed at the connection.
- Solid Brass Body: Brass shrugs off the moisture, road salt and compressor oil inside a heavy-duty air system and will not gall into the valve body.
- DOT / FMVSS 571.106 Compliant: Approved for heavy-duty air brake systems, so the repair passes inspection instead of failing it.
