Parker 62PLP-4-2 Unequal Union Push-to-connect Fitting

Product Description

The PARKER 62PLP-4-2 is a push-to-connect unequal union tube fitting designed to join two tubes of different outside diameters without tools or ferrules. Constructed from nickel-plated brass with a nitrile O-ring seal, this fitting handles a maximum working pressure of 300 psi across a temperature range of 0 to 200 degrees F. The release button is made from a black, flame-resistant material rated to the UL94 V-0 standard, making it suitable for installations where fire resistance is a code consideration. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this fitting in instrumentation lines, pneumatic controls, and fluid-handling systems where a fast, reliable tube connection is required.

The 62PLP-4-2 connects a 1/4-inch OD tube to a 1/8-inch OD tube in a straight union configuration. It is suited for residential and light commercial applications including pneumatic control lines, compressed-air instrument circuits, and low-pressure fluid systems. The push-to-connect design allows quick assembly and field disassembly without specialty tooling, reducing installation time on panel builds and equipment retrofits. Nickel plating adds corrosion resistance for installations in humid or mildly aggressive environments.

Key Features

• Connects 1/4-inch OD tube to 1/8-inch OD tube in a single straight union body
• Rated to 300 psi maximum working pressure
• Operating temperature range of 0 to 200 degrees F
• Nickel-plated brass construction for corrosion resistance
• Nitrile O-ring seal for compatibility with common pneumatic and fluid media
• UL94 V-0 rated flame-resistant release button

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for pneumatic instrument lines, compressed-air control circuits, and low-pressure fluid tubing systems using 1/4-inch and 1/8-inch OD tubing.

Installation Notes

This fitting is installed by licensed plumbers, HVAC technicians, or instrumentation mechanics. Before installation, depressurize and isolate the line completely. Ensure the tube end is cut cleanly and squarely with no burrs, as irregular cuts can compromise the O-ring seal. To disconnect, press the release collar fully against the fitting body before pulling the tube free.
