Parker 62PLP-5 Push-to-connect Union 5/16 Inch Od

Product Description

The PARKER 62PLP-5 is a push-to-connect union tube fitting designed for straight tube-to-tube connections in pneumatic and fluid transfer systems. Constructed from nickel-plated brass with a nitrile O-ring seal, it handles up to 300 psi working pressure and a temperature range of 0 to 200 degrees F. The collet-style push-to-connect design allows fast, tool-free tube insertion and secure retention without ferrules or compression nuts. The release button is made from a black flame-resistant material rated to UL94 V-0, making it suitable for environments where ignition resistance is required. Plumbers, HVAC technicians, and instrumentation technicians install this fitting in air, water, and compatible fluid lines.

This union fitting is used in residential and light commercial applications where two tube runs of the same outside diameter must be joined in-line. Typical install scenarios include pneumatic control lines, compressed air distribution, low-pressure fluid circuits, and HVAC ancillary tubing. It accepts 5/16 inch OD tubing on both ends and allows inline connection without the need for wrenches or thread sealants. The overall assembled length is 1.65 inches, making it compact enough for tight panel or cabinet installations.

Compatibility

Designed as an OEM-style push-to-connect union for systems using 5/16 inch OD tubing in pneumatic, compressed air, or low-pressure fluid applications.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation mechanics depending on the system type. Depressurize and drain the line completely before removing or installing any fitting. Insert tubing fully until it seats against the internal stop — partial insertion is a common source of leaks. To disconnect, depress the release collar evenly and withdraw the tube; inspect the tube end for squareness and burrs before reinserting.
