Overview
Brass reducing bushing, 3/8 inch male NPT × ¼ inch female NPT. CCW part code BR192.
It is a plumbing adaptor: it takes a 3/8 inch female port down to a ¼ inch male fitting. In truckmount and portable plumbing, that is one of the most frequently needed size changes there is.
Specifications
- Male thread: 3/8 inch NPT
- Female thread: ¼ inch NPT
- Material: brass
The pressure rating is not stated in our supplier record, and we are not going to publish a figure we cannot verify. If you are fitting this on a high-pressure solution line, ask us for the rating first.
Reading the size correctly
Bushings are described male-first, and getting that the wrong way round is the single most common ordering mistake with fittings. This one is 3/8 male into ¼ female: it screws into a 3/8 inch female port, and a ¼ inch male fitting screws into it.
If you need the opposite — a ¼ inch male into a 3/8 inch female — that is a different part. HydraMaster list 052-061 (3/8" NPT × ¼" FPT) and 052-064 (½" NPT × 3/8" FPT) among others. Ask us and we will pick the right one.
Fitting advice
NPT is a tapered thread. It seals on the thread, which means it needs sealant — PTFE tape or a liquid thread sealant suited to the temperature and chemistry. Start the tape two threads back from the end so you do not push a tail of tape into the line.
Do not over-tighten brass into brass. A tapered thread wound in too hard will split a female port, and on a manifold that turns a fifty-cent fitting into a real repair.
Each reduction adds a restriction. On a solution line, stacking adaptors to reach the size you want costs pressure at the tool — if you find yourself using three fittings to make one connection, it is worth getting the right single fitting instead.
Frequently asked questions
Which end goes where?
The 3/8 inch male end screws into a 3/8 inch female port. A ¼ inch male fitting screws into the other end.
What pressure is it rated to?
Not stated in our record. Ask us before using it on a high-pressure line.
Is it brass or brass-plated?
Brass.
Do I need thread tape?
Yes. NPT seals on the thread.
Will it suit a HydraMaster machine?
The thread sizes are standard NPT, so mechanically yes. If you are replacing a specific fitting in a documented assembly, tell us the machine and position and we will check the HydraMaster part number rather than have you substitute on assumption.
Working out a fitting run? Tell us what is at each end and we will spec it for you rather than have you order twice.
