Parker KP23867 Push-to-connect Union Fitting 1/2 in Od

Product Description

The PARKER KP23867 is a push-to-connect union tube fitting designed for tube-to-tube connections in fluid and pneumatic systems. Constructed from nylon, this fitting accepts 1/2 inch outside diameter tubing on both ends and is rated to 290 psi. The push-to-connect design allows for fast, tool-free tube insertion, reducing installation time compared to traditional compression or threaded fittings. It is well suited for low- to medium-pressure plumbing, pneumatic control lines, and fluid transfer applications where a secure, leak-resistant union connection is required. Each package contains 2 fittings.

This fitting is used in residential and light commercial applications where nylon push-to-connect unions provide a practical alternative to metal fittings in non-corrosive, moderate-pressure environments. Typical install scenarios include compressed air distribution lines, water supply tubing runs, and pneumatic control circuits. Plumbers, HVAC technicians, and pneumatic system installers commonly use this type of fitting when routing 1/2 inch OD tubing through equipment panels, manifolds, or utility systems where quick disconnection and reconnection are an operational advantage.

Compatibility

Designed as an OEM-style push-to-connect replacement union for systems using 1/2 inch outside diameter tubing in compatible fluid and pneumatic applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pneumatic system technicians. Before installing or removing this fitting, depressurize and isolate the line completely. Ensure tubing ends are cut square and deburred for a proper seat and leak-free seal. Follow applicable codes, including IPC or IFGC guidelines as relevant to the system type, when integrating push-to-connect fittings into pressurized service lines.
