Overview

Get a 1/4in fitting into a 3/8in port with one part. This Brass Reducer Bushing distributed by FleetPro Parts & Tires converts a 3/8in male NPT thread down to a 1/4in female NPT thread - the everyday fix when a valve, tank or manifold port is one size larger than the fitting the job actually calls for. Forcing the wrong thread into a port chews it out, and a chewed port turns a two-dollar fitting problem into a component replacement. 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.

Right Size, One Part: The 3/8in to 1/4in NPT Bushing Advantage

A reducer bushing is the shortest possible path between two thread sizes: 3/8in male NPT outside, 1/4in female NPT inside, one piece and one added joint. It keeps the small fitting tight against the port instead of hanging it off a nipple where vibration can work it loose, and it lets a shop stock one size of gauge, valve or air line and still land it in whatever port the chassis provides.

Brass is the reason it comes back out. Brass tapered pipe thread seals without galling on assembly and does not seize into the port after a few salted winters, so removing the bushing later does not cost you the component it is screwed into. This Automann bushing is a direct replacement for highly searched industry numbers including Eaton 3220X6X4, Parker 209P64, 110CB and SPRB64.
