Parker PT-00135 Flareless Bite-type Tube Union 1/2 in Steel

Product Description

The PARKER PT-00135 is a flareless bite-type tube union designed for high-pressure hydraulic and instrumentation tubing systems. It creates a secure, leak-resistant connection between two lengths of tubing without requiring a flared end. The fitting is manufactured from steel and rated to a maximum working pressure of 5,000 psi, making it appropriate for demanding fluid power and control line applications. With an overall length of 2.31 inches and a 37-degree flared angle geometry, this straight union is sized for 1/2-inch outside diameter tubing. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers for this type of fitting.

This fitting is suited for industrial, commercial, and mobile hydraulic applications where tube unions are required in high-pressure steel tubing runs. It is commonly installed in fluid power systems, process control lines, and heavy equipment hydraulic circuits. The bite-type design eliminates the need for a separate flaring operation, simplifying installation in the field or on the bench. Sold in a package quantity of five units per pack.

Compatibility

Designed as an OEM-style flareless bite-type union for 1/2-inch outside diameter steel tubing in high-pressure hydraulic and instrumentation systems.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician following the tube fitting manufacturer's assembly procedure, which typically involves an initial pre-swaging step to seat the ferrule before final torque. Depressurize and isolate the tubing circuit completely before disassembling any fittings. Use a calibrated torque wrench and follow published turns-past-finger-tight specifications from the fitting manufacturer rather than improvising. Verify tubing OD tolerance and wall thickness meet the fitting manufacturer's requirements before assembly.
