Parker 66PLP-2-4 Push-to-connect Female Connector

Product Description

The PARKER 66PLP-2-4 is a push-to-connect female connector fitting designed for tube-to-female NPT inline connections in pneumatic and fluid control lines. It accepts 1/8 inch OD tubing on both tube ports and connects to a 1/4 inch NPTF female thread at the center body. Constructed from nickel-plated brass, the fitting is rated for a maximum working pressure of 300 psi and a temperature range of 0 to 200 degrees F. The push-to-connect mechanism allows tool-free tube insertion and quick-release without special tooling, making it a common choice for technicians assembling or servicing compressed air, instrumentation, and light fluid circuits.

This fitting is suited for residential and light commercial HVAC control lines, refrigeration instrumentation tubing, pneumatic actuator circuits, and general compressed-air plumbing where a reliable inline female connection is needed. The nitrile O-ring provides a positive seal on 1/8 inch OD tubing, and the black flame-resistant button is rated to UL94 V-0, making it appropriate for installations where ignition resistance is specified. It is sold and typically installed as a single unit, and its compact profile suits tight panel or manifold configurations.

Compatibility

Designed as an OEM-style push-to-connect fitting for 1/8 inch OD tubing systems with 1/4 inch NPTF female thread ports, suitable for compressed air, pneumatic control, and light instrumentation fluid circuits.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or instrumentation mechanics. Depressurize and isolate the line completely before installing or removing the fitting. Confirm the receiving female thread is NPTF and apply appropriate thread sealant per job specifications before engagement. When inserting tubing, push firmly until the tube seats fully against the internal stop; to release, depress the collar button and withdraw the tube.
