Parker 32PTC-8 Push-to-connect Union Tube Fitting

Product Description

The PARKER 32PTC-8 is a push-to-connect union tube fitting designed to join two tube runs without tools or thread preparation. It accepts tubing with a 1/2 inch outside diameter and delivers a rated working pressure of 250 psi. The composite body keeps weight low at 0.04 pounds while resisting corrosion in a range of fluid-handling environments. A nitrile o-ring provides the primary seal, making this fitting suitable for systems where petroleum-based fluids or moderate-temperature media are present. Plumbers, HVAC technicians, and mechanical contractors install this fitting in low-pressure pneumatic, water, and process lines where a fast, reliable connection is required.

This union fitting is used in residential and light commercial plumbing, HVAC, and fluid distribution systems where two tube ends must be joined in a straight run. The push-to-connect design allows the tube to seat and seal in a single motion, reducing installation time compared to compression or soldered alternatives. It is well suited for service and repair applications where access is limited or repeat disconnection may be needed.

Key Features

• Push-to-connect design: no tools, solder, or thread tape required for installation
• 1/2 inch OD tube compatibility on both ends for a straight union connection
• 250 psi working pressure rating for low-to-medium pressure systems
• Composite body construction for corrosion resistance and reduced weight
• Nitrile o-ring seal compatible with petroleum-based and water-based media

Compatibility

Designed as an OEM-style push-to-connect union fitting for 1/2 inch outside diameter tubing in plumbing, HVAC, and general fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the system completely before cutting or modifying any tubing. Ensure the tube end is cut square, deburred, and clean before inserting it into the fitting to achieve a proper seal. To release the tube, depress the collet release ring evenly while pulling the tube straight out.
