Parker PT-00131 Flareless Bite-type Tube Union 3/4 in

Product Description

The PARKER PT-00131 is a flareless bite-type tube union designed to create a leak-resistant, permanent connection between two lengths of tubing without the need for flared tube ends. The union accepts 3/4 inch outside diameter tubing and uses a ferrule-based bite action to grip and seal as the fitting is tightened. This style of fitting is common in hydraulic lines, instrumentation tubing, fuel systems, and refrigeration or HVAC piping where a reliable inline union is required. Licensed plumbers, HVAC technicians, and fluid-system technicians are the typical installers for this type of component.

This fitting is suited for inline tube joining applications across residential and commercial systems where tube flaring is not practical or preferred. Flareless bite-type unions are widely used in instrumentation runs, hydraulic circuits, and process fluid lines. The 3/4 inch tube OD sizing covers a common range of medium-diameter tubing used in mechanical and HVAC system installations. Each package contains 2 units.

Compatibility

Designed as an OEM-style inline union for use with 3/4 inch OD tubing in hydraulic, instrumentation, and fluid-handling systems requiring a flareless bite-type connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or hydraulic systems technician familiar with flareless compression-style fittings. Depressurize and drain the system fully before removing or installing any tube fittings. Follow the fitting manufacturer torque and assembly procedure for bite-type ferrule fittings to ensure the ferrule seats correctly without over-tightening. Verify tube OD and wall thickness are within the fitting's rated range before assembly.
