3/8″ Tube x 1/8 NPT Air Brake Push-In Male Connector
$9.00
Straight brass DOT push-in male connector joins 3/8-inch OD nylon air-brake tubing to a 1/8 NPTF female pipe port, with integrated tube support and a release collet for servicing compatible truck and trailer pneumatic systems.
Part number DQ68DOT0602.
Description
Overview
The 3/8 x 1/8 NPT male connector joins 3/8-inch outside-diameter nylon air-brake tubing to a 1/8 NPTF female pipe port. Its straight brass body connects the tube to smaller threaded pneumatic ports without an adaptor.
Features
- Push-in connection grips 3/8-inch OD imperial nylon air-brake tube.
- 1/8 NPTF tapered male pipe thread fits a matching female port.
- Integrated tube support and gripping collet replace loose compression components.
- Releasable collet allows tube removal during pneumatic servicing.
Specifications and Materials
The brass body combines the tube grip, support and seal. Its hexagon allows tightening without twisting the nylon line. Unlike metric M-series fittings, the tapered pipe-thread end does not use a metric face-sealing connection.
Part number: DQ68DOT0602.

Compatibility and Fitment
Match the 3/8 x 1/8 NPT male connector to 3/8-inch OD (9.525mm) nylon air-brake tube and a 1/8 NPTF female port. The 1/8-inch figure is the nominal pipe thread, not a tube dimension. BSP and NPT threads differ, even when they appear similar. Check tube wall thickness against the internal support.

Compliance and Safety
Depressurise the circuit before removal. Cut the tube squarely, discard damaged ends and insert it fully into the collet. Tighten through the hex using the specified NPTF sealing method, without overtightening the small port. Restore pressure gradually and leak-test both connections.
Trailer Applications
Use it on compatible trailer brake-control valves, pneumatic blocks and auxiliary equipment where a 3/8-inch line enters a 1/8 NPTF port in line.

Why Choose ICS Trailers
For an unmarked connector, send ICS Trailers the tube OD, port thread and a photograph. This helps distinguish the 1/8 NPTF version from BSP alternatives.
