Parker 62PLPBH-4M Bulkhead Union Fitting 4mm 300 Psi

Product Description

The PARKER 62PLPBH-4M is a push-to-connect bulkhead union fitting designed for straight tube-to-tube connections through a panel or bulkhead wall. Constructed from nickel-plated brass, it accepts 4mm outside diameter tubing on both ends and handles a maximum working pressure of 300 psi. The silver body and yellow release button provide a reliable, tool-free connect and disconnect at the fitting. Licensed plumbers, HVAC technicians, and fluid systems technicians install this type of fitting in pneumatic and fluid control lines where a tube run must pass cleanly through a panel or enclosure wall.

This fitting is suited for light industrial, commercial, and OEM pneumatic plumbing applications where compact bulkhead pass-throughs are required. The push-to-connect design allows for fast field installation without soldering, flaring, or compression tools. It is appropriate for use in enclosures, control panels, and equipment cabinets where 4mm tubing lines require a secure, sealed panel penetration. Operating temperature range spans 0 degrees F to 200 degrees F, making it suitable for most indoor mechanical and process environments.

Key Features

• Push-to-connect design allows tool-free tube insertion and release via yellow button
• Nickel-plated brass construction provides corrosion resistance in typical service environments
• Rated to 300 psi maximum working pressure
• Accepts 4mm outside diameter tubing on both ports
• UL94 V-0 flame resistance rating and silicone-free grease for compatibility with sensitive systems
• Straight bulkhead union configuration for clean panel pass-through installations

Compatibility

Designed as an OEM-style push-to-connect bulkhead union for pneumatic and fluid tubing systems using 4mm outside diameter tubing where a straight panel pass-through connection is required.

Installation Notes

Depressurize and isolate the tubing line completely before installing or removing this fitting. Ensure the panel or bulkhead hole is sized correctly for the fitting body and that tubing is cut cleanly and squarely before insertion. A licensed technician or qualified mechanic should verify that system pressure does not exceed the 300 psi rating. To release tubing, press the yellow release button fully while pulling the tube free.
