Description

Overview

The 1/4 NPSF x M22x1.5 male adaptor changes an imperial female connection to a metric male connection in a compact straight fitting. Its low-profile hex body provides spanner access where space is limited.

Features

• 1/4 NPSF female port accepts a matching imperial fitting.
• M22x1.5 male thread uses a face seal.
• Includes the M22 thrust washer and O-ring.
• Brass body provides a straight internal passage.

Specifications and Materials

This brass reducing bush combines a 1/4 NPSF female connection with an M22x1.5 male connection. The metric side seals against the port face with the included O-ring and thrust washer rather than relying on the thread alone. Working pressure depends on the connected equipment, system medium and installation conditions.

Part number: 0324-M22EN04A.

Compatibility and Fitment

Confirm the female side requires 1/4 NPSF and the receiving port uses an M22x1.5 thread with a flat sealing face. The main mismatch risks are confusing the imperial port with 1/4 BSP or choosing an M22 thread with another pitch. Also check that the 1/4 NPSF x M22x1.5 male adaptor leaves enough clearance for the connected valve, gauge or fitting.

Compliance and Safety

Depressurise the system before removal. Inspect the O-ring, washer, port face and both threads for cuts, flattening or contamination. Then tighten with the hex body while keeping side load off the connected component. Do not apply thread sealant to the metric face-sealing area, and leak-test both connections after restoring pressure.

Trailer Applications

Workshops use this adaptor to connect imperial-threaded gauges, pressure switches, valves and pneumatic fittings to M22 ports on truck and trailer equipment. It can also raise a component above the mounting face when nearby hardware restricts access.
