Brass Street Elbow 90 Degree - 3/8" NPT Air Line Fitting - Replaces Eaton 3400X6 Parker 2202P66 177.9116C

Turn an air line hard around a corner with this brass street elbow distributed by FleetPro Parts & Tires. It is shop-grade NPT pipe connection hardware for truck and trailer air-brake and air-accessory plumbing: a 90 degree elbow whose ends each fit 3/8 in pipes, so a line can leave a valve or a tank boss at a right angle instead of being bent into a stress riser. A weeping, cross-threaded or corroded fitting bleeds a reservoir down overnight, drags governor cut-in pressure down, sets off the low-air warning and can leave a tractor sitting on its spring brakes in the morning. 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.

A Clean 90 Degree Turn: The Brass Street Elbow Advantage

The value of a street elbow is that the turn happens inside the fitting instead of inside the line. Nylon air tubing that is forced around a tight radius work-hardens, flattens and eventually chafes through against whatever it is pressed into, and that failure always shows up months later at the worst possible time. Putting a 90 degree brass elbow at the port lets the tubing leave straight and relaxed. Both ends are tapered pipe thread, so the seal is made by the threads pulling together under sealant tape or pipe dope rather than by a gasket that can blow out - start it by hand, keep the wrench on the flats, and stop when it is snug.

The brass body is the shop standard for air system plumbing. It handles 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, so the next technician can still get it apart. At FleetPro Parts & Tires, we know an air system is only as good as its weakest joint.
