Description

Overview

This 3/4 x 3/4 NPT male connector provides a straight connection between 3/4-inch outside-diameter nylon air brake tubing and a 3/4-inch female NPTF threaded port. Its push-to-connect design allows the tube to be fitted without a conventional compression nut and olive, making it a practical choice for pneumatic repairs where access is limited.

Features

• Straight brass connector with an imperial push-in tube connection.
• 3/4-inch NPTF male threaded end.
• Integrated collet for releasing and reconnecting suitable tubing.
• Designed for compatible DOT air brake pneumatic systems.

Specifications and Materials

• Tube connection: 3/4-inch OD (19.05 mm) imperial nylon air brake tube.
• Thread connection: 3/4-inch male NPTF.
• Configuration: Straight male connector.
• Body material: Brass.
• Connection method: Push-to-connect tube fitting.
• Part number: DQ68DOT1212.

See the GP Truck Products imperial male connector specifications.

Compatibility and Fitment

Check both connection sizes before ordering. The 3/4 x 3/4 NPT male connector accepts tubing measured by its outside diameter, while the threaded end uses a nominal pipe-thread size. A 3/4-inch tube connection does not mean the male thread measures 3/4 inch across its outside diameter.

Confirm the mating port has the correct NPTF thread. BSP threads are not direct substitutes, even where the nominal sizes appear similar.

Related Parts

Other connection sizes and configurations are available for installations requiring a different tube diameter, thread size or fitting direction.

Compliance and Safety

Depressurise the air system before removing or installing the fitting. Cut the nylon tube squarely, check for surface damage and insert it fully into the push-in connection. Follow the applicable thread-sealing procedure, avoiding excess sealant entering the air passage. After installation, restore pressure and check both the threaded connection and tube entry for leaks.

Trailer Applications

This fitting is suited to compatible heavy-vehicle air brake plumbing where a larger 3/4-inch nylon air line must connect directly to a threaded valve, manifold or other pneumatic component. The straight layout is useful where the tube can approach the port without requiring an elbow.
