3/8″ Tube x M16 Air Brake Push-In Male Connector
3/8″ Tube x M16 Air Brake Push-In Male Connector
$18.00
Straight brass DOT push-in male connector joins 3/8-inch OD nylon air-brake tubing to an M16 x 1.5 female metric port. Features an integrated gripping collet and tube support for compatible truck and trailer pneumatic connections.
Part number 88-003-06M16.
Description
Overview
The 3/8 x M16 male connector joins 3/8-inch outside-diameter nylon air-brake tubing to an M16 x 1.5 female metric port. This straight brass push-in fitting connects imperial air lines to metric-threaded pneumatic components without an additional adaptor or elbow.
Features
- Push-to-connect opening accepts 3/8-inch OD imperial nylon tubing.
- M16 x 1.5 external male metric thread.
- Brass hexagonal body provides a tightening surface.
- Integrated gripping collet and internal tube support.
- Release collet permits tube removal during servicing.
- Straight configuration maintains alignment between the tubing and threaded port.
Specifications and Materials
The QAF3-style connector uses a brass body with an integrated push-in tube connection. Its retained collet, internal support and sealing components allow nylon tubing to connect without a separate compression nut or olive. The M16 male end uses a parallel metric thread rather than a tapered NPT or BSP connection.
Part number: 88-003-06M16.

Compatibility and Fitment
The 3/8 x M16 male connector requires 3/8-inch OD (9.525mm) nylon tubing and an M16 x 1.5 female threaded port. Measure the tubing outside diameter and confirm the port thread pitch before installation. Do not substitute 8mm or 10mm metric tubing, or attempt to install the fitting into M12, M14, M22, BSP or NPT ports.
Check the existing port’s sealing face and the replacement fitting’s sealing arrangement. Matching the thread alone does not guarantee a suitable pneumatic seal.

Compliance and Safety
Depressurise the pneumatic circuit before installation. Cut the nylon tubing squarely, remove damaged or distorted ends and insert the tube fully into the collet. Tighten the fitting through its hexagonal body using the correct sealing arrangement for the port. Restore pressure gradually and leak-test both connections.
Trailer Applications
This fitting suits compatible truck and trailer brake-control valves, air-suspension equipment and auxiliary pneumatic manifolds using 3/8-inch imperial nylon air lines with M16 metric connections. Its straight arrangement suits installations where the tubing approaches the port directly.
