Parker 66PLPBH-8-6 Female Bulkhead Push-to-connect Fitting

Product Description

The PARKER 66PLPBH-8-6 is a push-to-connect female bulkhead tube fitting designed for inline tube connections through a panel or bulkhead wall. Constructed from nickel-plated brass, it accepts 1/2 inch OD tubing on both tube ports and threads into a 3/8 inch NPTF female connection. The fitting is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 200 degrees F. The push-to-connect mechanism uses a nitrile O-ring for a reliable seal, and the release button is made from black flame-resistant material rated to UL94 V-0. Licensed plumbers, HVAC technicians, and fluid-systems installers use this fitting in pneumatic and fluid-transfer lines.

This fitting is suited for residential and light commercial applications where a tube line must pass through a panel wall or bulkhead and terminate with a female NPT connection on one side. The push-to-connect ends allow fast, tool-free tube insertion on both tube ports, reducing installation time in tight spaces. Typical applications include pneumatic control lines, fluid-transfer systems, and HVAC accessory tubing where a bulkhead pass-through is required. The NPTF thread form provides a pressure-tight seal without relying solely on thread sealant.

Compatibility

Designed as an OEM-style push-to-connect bulkhead fitting for pneumatic and fluid-transfer systems using 1/2 inch OD tubing and 3/8 inch NPTF female port connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and system design requirements. Depressurize and isolate the line before disconnecting or installing any fitting. Insert tubing fully into the push-to-connect port until it seats against the internal stop; confirm the tube is locked by applying light pull-back tension. Apply appropriate thread sealant or PTFE tape to the NPTF threads per system specifications before mounting through the bulkhead panel.
