PATIKIL Model 1 Brass Hex Bushing, 1/4" NPT Female to 1/8" NPT Male, 2-Pack

Some plumbing adjustments call for a fitting that joins different thread sizes, while others need a straight extension. This PATIKIL brass hex bushing combines both connection sizes in one reducer adapter. Its female 1/4" NPT end and male 1/8" NPT end help connect compatible fittings, including shower and bathtub spout setups.

The essentials

Each bushing is made of brass and has a hexagonal exterior that makes it easier to tighten or loosen during fitting work. The reducer connects pipes or fittings with different diameters, helping create a transition between the two thread sizes rather than requiring both sides of a connection to match. The precise threads and brass construction suit hose systems and a range of fitting applications.

The set contains two bushings, useful when you need matching adapters for a project or want a second fitting on hand. Each has a listed length of 22.5 mm/0.89 inch. The specified operating pressure is 1200 psi, and the temperature range is -65℉ (-53℃) to 250℉ (121℃). These details help when comparing a fitting with the requirements of a particular connection.

Who it’s for

This set is intended for people adapting or extending compatible threaded fittings, such as those used with showerheads and bathtub spouts. It is also described for hose systems and connections in wet environments, grease, fuel and gas, refrigeration, instrumentation, and low- and medium-pressure pipework. As with any threaded adapter, match the NPT thread type and the female and male sizes to the fittings being joined. The brass pipe fittings are not suitable for drinking water.

For a shower or tub-spout project, the differing thread sizes can help bridge a compatible 1/4" female connection and 1/8" male fitting. If a project instead needs the same thread size on both ends, a reducer bushing is not the right type of connection, this set is for a size transition.

How to use it

Select the bushing for a connection where the fitting on one side accepts 1/4" NPT female threads and the other side needs a 1/8" NPT male thread. Align the threads with the compatible fittings and tighten using the hexagonal body, which provides a surface for turning the adapter. The hex shape also makes loosening more convenient when the connection needs to be adjusted or removed.

Before installation, identify the thread type and size at both ends of the connection, then confirm that the application falls within the listed pressure and temperature range. This helps ensure the adapter suits the intended setup, whether you are joining plumbing fittings or working with another listed pipework application.

What to clarify

What thread sizes does the bushing connect? It has a 1/4" NPT female end and a 1/8" NPT male end, allowing a compatible connection between those two sizes.

What is included in the set? The set contains two brass pipe fitting hex bushings.

Can these fittings be used for drinking water? No. The product is stated to be unsuitable for drinking water.

Should you buy it?

Choose this two-piece set when your project needs a brass reducer that transitions between 1/4" NPT female and 1/8" NPT male connections. The hex body supports practical tightening and loosening, while the specified pressure and temperature range helps you assess fit for a compatible application. It’s a useful match for adapting shower or bathtub fittings and other listed systems where those exact thread sizes are required.
