Overview
Bridge two female air ports the right way with this brass close nipple distributed by FleetPro Parts & Tires. It is shop-grade NPT pipe connection hardware for truck and trailer air-brake and air-accessory plumbing, carrying two 3/8 in male pipe ends on a short, fully threaded body. A weeping, cross-threaded or corroded nipple 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.
Leak-Free Air Lines: The Brass Close Nipple Advantage
A close nipple is the short, fully threaded nipple you reach for when two female 3/8 in NPT ports have to meet in a tight space - behind a frame rail, on top of an air tank, or where a valve has to sit hard against a manifold and there is simply no room for a run of pipe. 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 the thread by hand, keep the wrench on the flats, and stop when it is snug - overtightening a pipe fitting is what splits a cast valve body and turns a two-dollar repair into a two-hundred-dollar one.
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. This Automann nipple is a direct replacement for highly searched industry numbers including Eaton 3326X6 and Parker 215PN6, it replaces the earlier 177.9022, and it also crosses to reference numbers 112C, 016053 and S2156.
