Description

Overview

The 3/4 NPT reducing bush converts a larger 3/4 NPT female port to accept a smaller 1/2 NPT male fitting. Its compact hexagonal body keeps the adaptor close to the connected valve, tank or manifold, making it suitable for trailer pneumatic installations where space around the port is limited.

Features

• 3/4 NPT male external thread for the larger female port.
• 1/2 NPT female internal thread for the smaller male fitting.
• Hexagonal body provides spanner access for installation and removal.
• Brass construction for threaded pneumatic connections.

Specifications and Materials

Product type: reducing bush. Configuration: male-to-female threaded adaptor. Male connection: 3/4 NPT. Female connection: 1/2 NPT. Material: brass. Part number: 02N24-1208.

See the official IFS fitting catalogue

Compatibility and Fitment

Confirm that the receiving component has a 3/4 NPT female port and the fitting being installed has a 1/2 NPT male thread. The main ordering risk is reversing the male and female sizes or confusing NPT with BSP threads. The larger external thread enters the component, while the smaller internal thread remains accessible for the connected fitting.

Compliance and Safety

Depressurise the pneumatic system before removing or installing the bush. Clean both mating threads and apply a suitable pneumatic thread sealant to the male tapered connections without allowing sealant to enter the air passage. Start each connection by hand and tighten using the hex body. Do not force a fitting that binds early because mismatched or damaged threads can crack the connected port. Repressurise gradually and leak-test both joints.

Trailer Applications

Workshops fit this reducing bush when a trailer valve, air tank, manifold or pneumatic component has a 3/4 NPT port but the connected hardware uses a 1/2 NPT male thread. It changes the connection size without redirecting the air path, making it suitable for compact air brake, air suspension and auxiliary pneumatic plumbing.

Why Choose ICS Trailers

Reducing bushes can look nearly identical even when the thread standard or connection order differs. If the original fitting is difficult to identify, send clear photos and measurements of both threads so the team can help narrow down the correct size and configuration.
