Parker PT-00763 Flareless Bite-type Tube Plug 6mm

Product Description

The PARKER PT-00763 is a flareless bite-type tube plug designed to seal the open end of a 6 mm OD tube without requiring a flared fitting preparation. The bite-type design uses a ferrule or sleeve that mechanically grips the tube wall when tightened, creating a leak-resistant seal. This plug is used to cap off unused ports, dead-end branches, or open tube lines during system service, testing, or staged installation. It is appropriate for hydraulic, pneumatic, refrigeration, and fluid-distribution tubing applications where a clean, pressure-rated termination is needed. Licensed plumbers, HVAC technicians, and instrumentation technicians are the primary installers.

This plug suits 6 mm OD tubing in light industrial and commercial systems, including instrumentation lines, pneumatic control circuits, and hydronic or refrigerant distribution panels where metric tubing is used. It is packaged in quantities of 5, making it practical for service vehicles and panel shops that need to keep small-count spares on hand. Applications include capping test ports, sealing manifold outlets during phased commissioning, and isolating branch lines during system modifications.

Key Features

• Flareless bite-type design eliminates the need for flare preparation on 6 mm OD tube ends
• Mechanically grips the tube on installation for a secure, leak-resistant seal
• Compact form factor suits tight panel and manifold installations
• Sold in a 5-piece package to support service and stocking needs
• Compatible with metric tubing systems common in instrumentation and light industrial applications

Compatibility

Designed as an OEM-style replacement or service fitting for flareless bite-type tube systems using 6 mm OD tubing.

Installation Notes

Installation should be performed by a qualified technician familiar with flareless compression fittings. Depressurize and isolate the tubing circuit completely before installing or removing any tube plug. Finger-tighten the plug body onto the tube end, then advance with a wrench per standard bite-type fitting practice to engage the ferrule — do not overtighten, as this can distort the tube wall or damage the ferrule seat. Verify system integrity by pressure-testing the circuit after installation before returning the system to service.
