Parker 164PLP-5 Union Tee Tube Fitting 5/16 in Od 300 Psi

Product Description

The PARKER 164PLP-5 is a push-to-connect union tee tube fitting designed for tube-to-tube connections in fluid and pneumatic plumbing systems. Constructed from nickel-plated brass with a nitrile O-ring seal, it accepts 5/16 inch OD tubing on all three ports and requires no tools for assembly — tubing seats and locks by simple insertion. The fitting holds a maximum working pressure of 300 psi and is rated for service between 0 degrees F and 200 degrees F. The actuator button is made from a black flame-resistant material compliant with the UL94 V-0 standard. Licensed plumbers and HVAC technicians install this type of fitting in refrigeration, pneumatic control, and fluid-transfer applications.

This fitting is suited for residential and light commercial installations where quick, reliable tube-to-tube tee connections are needed without soldering or compression fittings. Common applications include pneumatic control lines, chilled water circuits, and instrumentation tubing runs. The push-to-connect design speeds up installations in tight spaces and reduces assembly time. The nickel-plated brass body provides corrosion resistance appropriate for both indoor and sheltered outdoor environments where moisture exposure is a concern.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off system pressure and depressurize all lines before connecting or disconnecting this fitting. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the push-to-connect ports. To release tubing, press the actuator button and withdraw the tube — never pull tubing without depressing the release collar, as this can damage the internal collet and O-ring seal.
