Description

Overview

The 12mm x M22 swivel male branch tee connects an M22x1.5 female port to a straight run of 12mm metric nylon air line. Two opposing ports carry the tube across the tee, while the threaded branch connects at the centre. The swivel base positions the tee without rotating the tube.

Features

• Two push-in collets accept 12mm outside-diameter air brake tube.
• Male branch configuration places the M22 connection perpendicular to the tube run.
• Includes a sealing O-ring and washer for the metric parallel thread.
• Brass body suits compact pneumatic plumbing.

Specifications and Materials

The fitting uses CA360 and CA377 brass with NBR tube seals. It includes the sealing O-ring and washer for the M22x1.5 parallel thread. Maximum working pressure is 150 PSI, with an operating range from -40°C to 104°C. Use compatible SAE J844 nylon air brake tubing cut square and free from surface damage.

Part number: 88-M012S-12M22.

The manufacturer technical specifications cover the matching configuration, materials and operating limits.

Compatibility and Fitment

Confirm both connections require 12mm outside-diameter tube and the mounting port uses an M22x1.5 female thread. Also check the fitting layout. A branch tee places the male thread beneath the centre of the tube run, while a run tee places it at one end. The 12mm x M22 swivel male branch tee must have enough clearance for the nut and body to turn into position.

Compliance and Safety

Depressurise the circuit before fitting or removing the tee. Inspect both tube ends, the collets, sealing washer, O-ring and port face. Then push each tube fully to its internal stop and leak-test all three connections after restoring pressure. Replace damaged seals rather than tightening against a cut or distorted O-ring.

Trailer Applications

Workshops use this branch tee to divide or combine airflow at valves, reservoirs, air suspension controls and auxiliary pneumatic equipment. Its aligned tube ports let the 12mm line continue straight while connecting through an M22 port.
