Parker 66PLPBH-5/32-4 Female Bulkhead Tube Fitting

Product Description

The PARKER 66PLPBH-5/32-4 is a push-to-connect female bulkhead tube fitting designed for inline tube-through-panel installations in pneumatic and fluid control systems. Constructed from nickel-plated brass, it accepts 5/32 inch OD tubing on both tube ports and threads into a panel or bulkhead via a 1/4 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 integrated push-to-connect mechanism allows fast, tool-free tube insertion and removal, making it a practical choice for technicians assembling or servicing control panels, instrumentation enclosures, and compressed-air distribution lines.

This fitting is suited for residential and commercial pneumatic control applications, instrumentation plumbing, and HVAC control panel assemblies where a tube line must pass cleanly through a panel wall. The bulkhead configuration allows technicians to route tubing from one side of an enclosure to the other without additional fittings or adapters. The nitrile O-ring construction supports compatibility with air and many common fluid media. Licensed HVAC technicians, instrumentation technicians, and industrial maintenance professionals are the typical installers of this fitting type.

Key Features

• Push-to-connect design on both tube ports allows tool-free tube insertion and release
• Nickel-plated brass body provides corrosion resistance in air and fluid service
• Rated to 300 psi maximum working pressure
• Operating temperature range of 0 degrees F to 200 degrees F
• Black flame-resistant button material meets UL94 V-0 flame-resistance standard
• Nitrile O-ring seals for reliable performance with air and compatible media

Compatibility

Designed as an OEM-style push-to-connect bulkhead fitting for pneumatic and fluid control systems using 5/32 inch OD tubing with 1/4 inch NPTF panel thread connections.

Installation Notes

Installation is performed by instrumentation or HVAC technicians. De-pressurize and lock out the pneumatic or fluid system before removing or installing any fittings. Ensure the panel hole is sized correctly for the bulkhead thread and that the NPTF thread engagement is sealed appropriately per applicable piping codes. Tube ends should be cut cleanly and squarely to ensure a proper push-to-connect seal; damaged or burred tube ends can compromise the O-ring seat.
