Description

Overview

The 3/8 tube plug closes an unused 3/8in push-to-connect port in a trailer air brake or auxiliary pneumatic circuit. Its solid stem enters the fitting like a short tube section, while the flanged head provides a grip point for removal. This part blanks the fitting port, not the open end of nylon air line.

Features

• Solid 3/8in imperial stem suits matching push-in fitting ports.
• One-piece plastic construction resists corrosion.
• Wide collar limits insertion and aids removal.
• Works with the receiving fitting’s collet and internal seal.

Specifications and Materials

This black plastic blanking plug has no thread, hose connection or separate sealing washer. Instead, the installed fitting grips and seals around the stem, so its collet and O-ring must remain serviceable.

Part number: 88-065-06.

Compatibility and Fitment

Match the 3/8 tube plug to an imperial 3/8in push-in port. Do not substitute a 10mm metric plug, even though the sizes look close, and do not order this part when you need to cap exposed tube. Push the stem fully through the collet, then pull back gently to confirm engagement. These cross-references show where this part replaces the part numbers and applications listed. Some installations may need minor changes. GP-064-P06, GP064P06

Compliance and Safety

Release all air pressure before fitting or removing the plug. Inspect the receiving port for a damaged collet, cut seal, dirt or scoring because the plug cannot correct a worn fitting. After installation, restore pressure gradually and check around the port with an approved leak-detection method before returning the trailer to service.

Trailer Applications

Workshops fit this plug when a spare outlet on a push-in tee, union, valve or manifold needs closing during air-line repairs or circuit changes. It also suits breakdown fitting kits carried for roadside pneumatic work.
