Parker PT-00129 Flareless Bite-type Tube Union 1/2 in

Product Description

The PARKER PT-00129 is a flareless bite-type tube union designed to create a secure, leak-resistant connection between two tube runs without requiring flared ends. The fitting uses a ferrule-based bite action to grip the tube wall mechanically, eliminating the need for flaring tools on-site. With a 1/2-inch tube outside diameter, this union suits medium-bore hydraulic, pneumatic, and fluid-handling lines commonly found in HVAC, refrigeration, and industrial process systems. Licensed plumbers, pipefitters, and HVAC-R technicians are the primary installers.

This fitting is suited for applications where rigid or semi-rigid tubing must be joined inline and flared connections are impractical or prohibited by the installation layout. Typical install scenarios include equipment rooms, rooftop mechanical systems, and industrial panels where vibration resistance and a compact footprint are priorities. The bite-type design is well-suited for high-pressure lines where tube pull-out resistance is required. This SKU is sold in a package quantity of 5 fittings.

Key Features

• Flareless bite-type design eliminates on-site flaring and reduces installation time
• Ferrule-action grip provides mechanical hold on the tube OD for pull-out resistance
• Union configuration allows inline connection of two tube segments
• 1/2-inch tube OD sizing fits common medium-bore rigid and semi-rigid tubing
• Sold in a pack of 5 fittings per SKU

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2-inch OD tube lines in hydraulic, pneumatic, and fluid-handling systems.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or HVAC-R technician familiar with flareless compression fittings. De-pressurize and isolate the line completely before disassembly or fitting installation. Tube ends must be cut square and deburred to ensure proper ferrule seating and a leak-free bite. Follow the applicable system pressure ratings and applicable plumbing or mechanical codes for the jurisdiction.
