Description

Overview

The 3/8 x 3/4 NPT male connector joins 3/8-inch outside-diameter nylon air-brake tubing to a 3/4 NPTF female pipe port. Its straight brass body connects a smaller air line directly to a larger threaded pneumatic port.

Features

• Push-in collet grips 3/8-inch OD imperial nylon tubing.
• 3/4 NPTF tapered male thread connects to a matching female port.
• Internal tube support and seal form the push-to-connect connection without a compression nut or olive.
• Release collet allows the tube to be removed for servicing.

Specifications and Materials

The brass body combines a gripping collet, internal tube support, pneumatic seal and tightening hex. Its 3/4-inch tapered male pipe thread differs from parallel metric fittings that seal against a port face.

Part number: DQ68DOT0612.

Compatibility and Fitment

Check that the nylon air line measures 3/8 inch (9.525mm) across its outside diameter and the receiving port has a 3/4 NPTF female thread. The 3/8 x 3/4 NPT male connector has only one tube connection: the second size denotes the thread. Allow room for the larger hex and avoid sharp tube bends. Do not substitute 10mm tubing or BSP threads.

Compliance and Safety

Depressurise the circuit before installation. Cut the tube squarely, push it fully into the collet and check its grip. Use the correct NPTF sealing method, then tighten through the brass hex without damaging the threads. Repressurise and leak-test both ends.

Trailer Applications

Use this connector on compatible trailer brake-control valves, air-suspension equipment and pneumatic manifolds where a 3/8-inch line enters a 3/4 NPTF port directly.
