Description

Overview

The 1/2 x M22 male connector joins 1/2-inch outside-diameter nylon air-brake tubing to an M22 x 1.5 female metric port. Its straight brass body connects larger imperial air lines directly to metric-threaded valves, manifolds and pneumatic equipment without an additional adaptor.

Features

• Push-in connection accepts 1/2-inch OD imperial nylon air tubing.
• M22 x 1.5 parallel male metric thread.
• Includes a captive washer and O-ring for sealing against the mating port face.
• Integrated gripping collet, internal tube support and release mechanism.

Specifications and Materials

The brass connector incorporates a push-in tube grip and internal pneumatic seal. Its M22 threaded end comes assembled with a sealing washer and O-ring, eliminating the need to purchase these components separately. The hexagonal body provides a tightening surface, while the collet allows tube removal without disconnecting the threaded fitting.

Part number: DQ68DOT08M22.

See the manufacturer imperial-to-metric male connector specifications

Compatibility and Fitment

Confirm the nylon tube measures 1/2 inch (12.7mm) across its outside diameter and the receiving port has an M22 x 1.5 female thread. The 1/2 x M22 male connector requires a suitable flat sealing face for its washer and O-ring. Do not substitute 12mm metric tube, 3/8-inch tubing, BSP threads or another M22 thread pitch.

Compliance and Safety

Depressurise the air circuit before installation. Cut the nylon tube squarely, remove damaged ends and push the tube fully into the collet. Inspect the M22 washer, O-ring and port face before tightening. Restore air pressure gradually, check tube retention and leak-test both connections.

Trailer Applications

Workshops fit these connectors to compatible truck and trailer air-brake valves, suspension-control manifolds and auxiliary pneumatic equipment using 1/2-inch nylon air lines. The straight connection suits installations where tubing approaches an M22 port directly.
