## Description

The brass construction gives this METALLIXITY hex bushing a durable, corrosion-resistant material for threaded pipe connections.

Each fitting adapts a 3/8" male NPT thread to a 1/4" female NPT thread, helping join components with different thread sizes.

With two bushings in the pack, you can keep a pair on hand for plumbing adjustments or maintenance. The listed applications include water lines, tub spouts and shower heads.

## Everyday use

A threaded size change can be useful when a water-line connection and the fitting it needs to meet have different NPT sizes. This bushing provides a male connection at 3/8" and a female connection at 1/4", so it can bridge those two thread sizes without changing the main focus of the setup. Match the fitting to compatible NPT threads on the components being joined.

For a home plumbing adjustment, for example, the bushing can serve as the connection between a 3/8" female NPT port and a 1/4" male NPT fitting. Its hex shape provides a form suited to tightening with a wrench during assembly. The brass material is valued for corrosion resistance, strength and wear resistance, making it a practical choice for pipe-fitting applications.

## Spec sheet

- Type: Hex bushing pipe fitting
- Material: Brass
- Connector: 3/8" male NPT to 1/4" female NPT
- Thread type: NPT
- Quantity: 2 pieces
- Listed applications: Water line, tub spout and shower head connections

## Where it shines

This fitting is useful when the connection sizes differ but both sides use the specified NPT thread arrangement. Rather than choosing a fitting with the same thread size at both ends, this bushing changes from 3/8" male to 1/4" female in one compact connection. That makes it relevant for adapting a compatible water-line connection or for plumbing work involving a tub spout or shower head.

The two-piece pack can also be handy for jobs involving more than one connection, or for keeping a second fitting available for a later repair. Brass is machinable and has good thermal conductivity, in addition to its corrosion and wear resistance—properties that make it a commonly used material for fittings handling fluids. For vehicle-related maintenance, pipe fittings also have applications in fluid, fuel, air, cooling and heating systems, the thread sizes and intended system still need to match the specific job.

## When it makes sense

Choose this METALLIXITY bushing when the connection calls for a 3/8" male NPT end on one side and a 1/4" female NPT end on the other. It’s a good fit if you need a straightforward threaded size adapter for a compatible water-line, tub-spout or shower-head connection, or want two brass fittings available for plumbing maintenance. Its clearly defined thread configuration and two-piece quantity make it easy to select for a specific connection task.
