Description

Overview

The 3/8 x M14 male connector joins 3/8-inch outside-diameter nylon air-brake tubing to an M14 x 1.5 female metric port. Its straight brass body connects an imperial air line directly to metric-threaded pneumatic equipment without an additional adaptor or elbow.

Features

• Push-to-connect opening accepts 3/8-inch OD nylon tubing.
• M14 x 1.5 external male metric thread.
• Captive O-ring provides sealing at the matching port face.
• Integrated release collet permits tube removal during servicing.
• Brass hexagonal body provides a dedicated tightening surface.

Specifications and Materials

The complete connector combines a brass body, internal tube support, gripping collet and pneumatic seals. The push-in connection requires no separate compression nut or olive. Its parallel metric thread uses a port-face sealing arrangement rather than relying on tapered pipe-thread interference.

Part number: DQ68DOT06M14.

Compatibility and Fitment

Before fitting the 3/8 x M14 male connector, confirm the nylon tube measures 3/8 inch (9.525mm) across its outside diameter. The receiving component must have an M14 x 1.5 female thread and a suitable sealing face. Do not substitute 8mm or 10mm metric tubing, M12 or M16 ports, or BSP and NPT threaded connections.

Compliance and Safety

Depressurise the air circuit before installation. Cut the nylon tubing squarely and remove damaged or oval sections before inserting it fully into the collet. Inspect the port-face O-ring and mating surface, then tighten through the brass hex without damaging the seal. Repressurise gradually and leak-test both connections.

Trailer Applications

This straight connector suits compatible truck and trailer brake-control valves, air-suspension equipment and auxiliary pneumatic manifolds using 3/8-inch imperial nylon tubing and M14 metric ports. The straight arrangement keeps the tube aligned with the component connection.
