Description

Overview

The 1/2 NPT male x 3/8 NPT female reducing bush adapts a larger female threaded port so it can accept a smaller male fitting. Its compact hexagonal body keeps the connection close to the component, which suits trailer pneumatic plumbing and workshop air systems where adding a longer adaptor would consume unnecessary space.

Features

• 1/2 NPT male external thread connects to the larger female port.
• 3/8 NPT female internal thread accepts the smaller male fitting.
• Hexagonal body provides spanner access during installation and removal.
• Brass construction suits threaded pneumatic connection work.

Specifications and Materials

Product type: reducing bush. Configuration: male-to-female threaded adaptor. Male connection: 1/2 NPT. Female connection: 3/8 NPT. Material: brass. Part number: 02N24-0806.

Check the dimensions and connection order in the official IFS fitting specifications

Compatibility and Fitment

Confirm the larger port is 1/2 NPT female and the part being installed has a 3/8 NPT male thread. The most common ordering mistake is reversing the male and female sizes or substituting a BSP fitting because the nominal dimensions look similar. The 1/2 NPT male x 3/8 NPT female reducing bush must screw into the larger port while leaving the smaller female opening accessible.

Compliance and Safety

Depressurise the air system before removing or installing the bush. Clean both mating threads, apply a suitable thread sealant to the male tapered connection and keep excess sealant out of the air passage. Start each thread by hand, then tighten using the hex body. Stop if the fitting binds early because mismatched NPT, BSP or damaged threads can split the port or distort the bush. Repressurise gradually and leak-test both threaded joints.

Trailer Applications

Workshops use reducing bushes when a trailer valve, air tank, manifold or pneumatic component has a 1/2 NPT port but the connected fitting or line hardware uses a 3/8 NPT male thread. The bush changes the port size without changing the direction of the air path, making it suitable for compact air brake, air suspension and auxiliary pneumatic repairs.

Why Choose ICS Trailers

Threaded reducers are easy to misidentify when several NPT, BSP and metric sizes are stored together. Send a photo of the old bush and measurements of both connections if the thread type or male-to-female order is uncertain.
