Description

Overview

The 1/2 x 3/8 NPT male connector joins 1/2-inch outside-diameter nylon air line to a 3/8 NPTF female port. Its straight brass body connects the tube directly to pneumatic equipment. The push-in grip needs no separate compression nut or olive, while the collet releases the tube for servicing.

Features

• Accepts 1/2-inch (12.7mm) OD nylon air tubing.
• Connects to a 3/8 NPTF female port.
• Brass hex body provides a tightening surface.
• Integrated grip, tube support and release collet.

Specifications and Materials

This DOT push-in fitting combines a brass body, collet, internal tube support and pneumatic sealing components. Its tapered male thread connects to the pipe port, while the opposite end grips imperial tubing by outside diameter.

Part number: DQ68DOT0806.

Compatibility and Fitment

When replacing a 1/2 x 3/8 NPT male connector, confirm the port accepts a 3/8 NPTF male thread and the tube measures 1/2 inch across its outside diameter. Do not substitute 12mm tubing for 12.7mm imperial tubing or confuse NPTF with BSP. Also check straight-entry clearance beside the valve or manifold.

Compliance and Safety

Depressurise the line first. Cut the nylon tube square, trim damaged ends and push it fully into the collet. Tighten through the hex using the correct method for the tapered thread, without overtightening the port. Then restore pressure and leak-test both connections.

Trailer Applications

Workshops fit these connectors to compatible trailer brake controls, air suspension plumbing and auxiliary pneumatic equipment with 1/2-inch lines and 3/8 NPTF ports.
