Overview

Split one air line into two without building a manifold. This Brass Female Tee distributed by FleetPro Parts & Tires carries a 3/8in female NPT pipe thread on all three ends, so a single run of air-brake or air-accessory plumbing can feed a second circuit - a gauge, a valve, an air horn, a second tank port - from one clean junction. Tapping a line with a cracked or improvised tee is how a shop ends up chasing a leak it cannot hear over the compressor. 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.

Three Ends, One Size: The 3/8in NPT Brass Tee Advantage

Every end on this tee is the same 3/8in female NPT, which is exactly what makes it easy to plumb: any male 3/8in pipe end goes into any leg, so the branch can leave in whichever direction the frame allows and there is no wrong way to orient the part on the bench. Each end fits 3/8in pipes, the size most air-brake and air-accessory plumbing already runs.

The brass body seals on tapered pipe thread and stays serviceable - brass does not gall on assembly and does not weld itself into the port over a few winters of road salt, so the next repair is a wrench job and not a drill-and-tap job. This Automann fitting is a direct replacement for highly searched industry numbers including Eaton 3700X6, Parker 2203P6, 101C and S2036, and it supersedes Automann 177.9007.
