Parker 66PLP-5/32-2 Push-to-connect Female Connector

Product Description

The PARKER 66PLP-5/32-2 is a push-to-connect female connector fitting designed for tube-to-female NPT inline connections in pneumatic and fluid control systems. Constructed from nickel-plated brass, it accepts 5/32 inch OD tubing on each tube port and connects to a 1/8 inch NPTF female thread. The fitting is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 200 degrees F. The release button is made from black flame-resistant material compliant with the UL94 V-0 standard. An internal nitrile O-ring provides a reliable seal. Licensed plumbers, HVAC technicians, and pneumatic system technicians install this fitting in compressed air, gas, and fluid distribution applications.

This fitting is suited for residential and light commercial pneumatic control systems, instrumentation lines, and HVAC control tubing runs where a secure push-to-connect inline female thread transition is needed. The NPTF thread form provides a pressure-tight mechanical seal without requiring thread sealant on low-pressure pneumatic service, though sealant is commonly applied in liquid or higher-pressure applications. Its compact overall length of 1.17 inches makes it practical in tight panel or manifold installations where space is limited.

Designed as an OEM-style push-to-connect fitting for pneumatic and fluid systems using 5/32 inch OD tubing with a 1/8 inch NPTF female port connection.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or pneumatic systems technician. Depressurize and isolate the system before removing or installing any fittings. Ensure tubing is cut cleanly and squarely and free of burrs before inserting into the push-to-connect port. Verify thread compatibility before engaging the NPTF connection, and follow applicable codes such as the IPC or IFGC for the fluid or gas service intended.
