Parker 66PLPBH-6M-4G Female Bulkhead Push-to-connect Fitting

Product Description

The PARKER 66PLPBH-6M-4G is a push-to-connect female bulkhead straight tube fitting designed for fast, tool-free tube connections through panel walls and bulkheads. Constructed from nickel-plated brass with a silicone-free grease formulation, it accepts 6mm outside diameter tubing on the push-to-connect end and terminates in a 1/4 inch BSPP female thread on the opposite side. Rated to 300 psi maximum working pressure, this fitting handles operating temperatures from 0 degrees F to 200 degrees F. The UL94 V-0 flame resistance rating makes it suitable for use in environments where fire resistance is a specification requirement. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting in compressed air, fluid transfer, and instrumentation lines.

This fitting is suited for residential and light commercial pneumatic or fluid system installations where a tube line must pass through or terminate at a panel, manifold, or enclosure wall. The straight bulkhead configuration allows secure panel mounting with tube connections made on both sides of the surface. The yellow release button provides a clear visual indicator for the push-to-connect mechanism during installation and tube removal. Applications include HVAC controls, pneumatic instrumentation, and general-purpose fluid handling lines that require a reliable, pressure-rated panel penetration fitting.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing or installing any fittings. Confirm thread type compatibility before installation, as BSPP threads are not interchangeable with NPT threads without appropriate adapters. Ensure tubing is cut cleanly and squarely and inserted fully until it bottoms out in the fitting body to achieve a proper seal.
