Parker PT-00773 Flareless Bite-type Tube Plug 18mm

Product Description

The PARKER PT-00773 is a flareless bite-type tube plug designed to seal hydraulic and fluid-system tubing with an 18 mm outside diameter. Bite-type fittings use a ferrule that deforms mechanically onto the tube during assembly, creating a reliable, leak-resistant seal without the need to flare the tube end. This plug terminates an open tube end to close off a line, cap an unused port branch, or isolate a section of a system during service. It is used by hydraulic technicians, industrial maintenance professionals, and HVAC-refrigeration mechanics who work with metric tube systems.

This plug is suited for metric tube assemblies where the tube outside diameter measures 18 mm. Flareless bite-type designs are commonly found in hydraulic power units, industrial fluid transfer systems, and refrigeration circuits that use metric tubing standards. The plug is well-suited for applications where the system requires a clean, permanent or semi-permanent line termination without flaring equipment on site. Sold in packages of 5 units.

Key Features

• Flareless bite-type design eliminates the need for tube flaring tools during assembly
• Fits 18 mm outside diameter tubing for metric system compatibility
• Mechanical ferrule deformation provides a secure, leak-resistant tube seal
• Compact plug form factor for terminating open tube ends or capping unused branches
• Packaged in quantities of 5 for shop-stock convenience

Compatibility

Designed as an OEM-style replacement or service component for metric fluid and hydraulic tube systems using 18 mm outside diameter tubing with flareless bite-type fitting standards.

Installation Notes

Installation is performed by hydraulic technicians or qualified mechanics working on pressurized fluid systems. Depressurize and drain the affected line completely before removing any existing fittings or installing this plug. Follow the fitting manufacturer's assembly procedure for ferrule bite-type connections, including proper tube insertion depth and the correct number of wrench turns from finger-tight. Consult applicable system design standards and local codes for pressure ratings and material compatibility before use.
