Parker 32PTC-4 Push-to-connect Union 1/4 in Od

Product Description

The PARKER 32PTC-4 is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Built from composite material with a nitrile O-ring, it accepts 1/4 inch OD tubing on both ends and holds a rated working pressure of 250 psi. The push-to-connect mechanism allows technicians to make fast, tool-free connections by inserting tubing directly into the fitting body until it locks. This fitting is installed by plumbers, HVAC technicians, and industrial maintenance professionals in a wide range of low- to medium-pressure service applications.

The 32PTC-4 is suited for residential and light commercial installations where quick-connect tube unions are needed without threaded or compression fittings. Typical applications include instrument air lines, pneumatic control tubing, water supply connections, and similar systems using 1/4 inch OD tubing. The composite construction makes it appropriate for environments where metal corrosion is a concern. Its compact profile fits in tight spaces where standard fitting assemblies would be difficult to install or service.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure locking
• Accepts 1/4 inch OD tubing on both ports for inline union connections
• Rated to 250 psi working pressure
• Composite body resists corrosion in compatible fluid and air service
• Nitrile O-ring seals provide reliable leak resistance across a broad temperature range

Compatibility

Designed as an OEM-style replacement or upgrade union fitting for systems using 1/4 inch OD tubing in pneumatic, instrument air, or fluid-transfer applications.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Before installing or removing the fitting, depressurize and isolate the line completely. Ensure tubing is cut cleanly and squarely and is free of burrs before insertion to achieve a proper seal. To disconnect, depress the release collar fully before pulling the tubing free to avoid damaging the internal collet or O-ring.
