Description

Overview

The 3/8 NPT hex plug closes an unused female NPT port in a pneumatic or air brake circuit. Its brass body suits service work where a removable threaded blank is needed, while the external hex head provides a positive surface for a spanner or socket during installation and removal.

Features

• 3/8 NPT male tapered pipe thread
• Brass construction for pneumatic fitting applications
• External hex head for controlled tightening
• Compact plug design for blanking an unused threaded port

Specifications and Materials

This fitting uses a 3/8 NPT male connection and a hex-head brass body. It measures 19.81 mm long and uses an 11/16 inch hex, providing a practical check for both overall fit and tool clearance. Part number: 02N64-06.

Compatibility and Fitment

Before fitting, match the 3/8 NPT hex plug to the female port thread. NPT is a tapered thread and must not be confused with BSP, metric or straight-thread ports of a similar visible diameter. Also check that the hex head has enough clearance for the installation tool. For sealing, use a thread sealant suitable for the air system and service conditions.

Compliance and Safety

Depressurise the pneumatic system before removing or fitting the plug. Inspect the female threads for damage, contamination or previous sealant, then tighten through the hex head without overtightening the brass body. After installation, restore pressure and check the closed port for leakage.

Trailer Applications

Truck and trailer workshops use this plug to close spare 3/8 NPT ports on compatible air valves, manifolds and pneumatic components. It also suits workshop air equipment where the thread form, pressure and operating medium are appropriate.
