Parker PT-00769 Flareless Bite-type Tube Plug 12mm

Product Description

The PARKER PT-00769 is a flareless bite-type tube plug designed to seal and cap 12 mm OD tubing in hydraulic and pneumatic fluid systems. The bite-type design uses a ferrule that bites into the tube wall to create a leak-resistant, mechanical seal without requiring tube flaring. This plug is suited for capping unused or temporary ports during system assembly, maintenance, or pressure testing. Licensed plumbers, pipefitters, and hydraulic technicians typically install these fittings in industrial and commercial fluid distribution lines where clean, secure tube termination is required.

This plug is used in flareless bite-type fitting systems across hydraulic, pneumatic, and process fluid applications. It is applicable in residential and light commercial HVAC refrigerant piping, industrial fluid control panels, and instrumentation tubing where 12 mm OD tube must be terminated or isolated. The PT-00769 is sold in packages of five, making it practical for service calls and panel builds where multiple ports may need to be capped during a single job.

Installation Notes

Installation is performed by licensed pipefitters, hydraulic technicians, or plumbers working on pressurized fluid systems. De-energize and fully depressurize the system before removing or installing any fittings. Ensure the tube end is cut square and deburred before seating the plug to allow the ferrule to bite correctly. Follow applicable system pressure ratings and local plumbing or fluid power codes when selecting and installing tube fittings.
