Overview
Change the sex of a 1/2 in air port without changing anything else using this brass adapter distributed by FleetPro Parts & Tires. It is shop-grade NPT pipe connection hardware for truck and trailer air-brake and air-accessory plumbing, with one 1/2 in male pipe end and one 1/2 in female pipe end on the same body. 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.
Same-Size Stand-Off: The 1/2 in Brass Adapter Advantage
The 1/2 in size is where the supply side of the system lives - compressor discharge, dryer feed, wet tank and service reservoir plumbing - and it is exactly where you do not want a tower of adapters hanging off a cast port. Because both ends of this adapter are the same 1/2 in NPT size, it stands a fitting off for clearance or adds a wrench flat to break a joint loose, in one piece instead of stacking extra hardware.
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. The brass body handles the moisture, road salt and compressor oil that live inside a heavy-duty air system and 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 adapter is a direct replacement for highly searched industry numbers including Eaton 3200X8 and Parker 222P88, it replaces the earlier 177.9623, and it also crosses to reference numbers 120DD and S1208.
