Midland Industries 860805A Union Bulkhead Adapter Brass

Product Description

The MIDLAND INDUSTRIES 860805A is a brass union bulkhead adapter designed to create a secure, panel-mounted connection between push-in tubing and female NPT threaded fittings. The 860805A connects a 1/2 inch push-in tube on one side to a 3/8 inch FNPTF port on the other, making it a practical solution for routing pneumatic or fluid lines through a bulkhead, enclosure wall, or panel. Rated to 150 psi maximum operating pressure and tested across a temperature range of -40 to 200 degrees F, this fitting is suited for demanding installations where a leak-free, through-panel transition is required. Plumbers, HVAC technicians, and pneumatic system technicians install this fitting in both shop and field environments.

The 860805A is used in applications requiring a through-panel or bulkhead tube routing solution, particularly in pneumatic control systems, compressed air distribution, and fluid transfer lines. Its D.O.T.-rated push-to-connect design makes it appropriate for commercial and industrial installations where tube retention and pressure integrity are critical. The FNPTF thread on the secondary port provides a standard female pipe thread connection compatible with common threaded fittings and valve bodies. This fitting is appropriate for both new installations and replacement work on existing bulkhead assemblies.

Key Features

• 1/2 inch push-in tube connection on one end for tool-free tube insertion and secure retention
• 3/8 inch FNPTF port on the secondary end for standard female pipe thread engagement
• 150 psi maximum operating pressure rating for pneumatic and fluid service
• Operating temperature range of -40 to 200 degrees F
• Brass construction for corrosion resistance and durability in wet or humid environments
• D.O.T.-rated push-to-connect design suitable for commercial and industrial use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for pneumatic control panels, compressed air systems, and fluid transfer assemblies requiring a push-to-connect tube-to-female-NPT bulkhead transition.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pneumatic systems technician. Depressurize and isolate the system fully before removing or installing any fitting. The push-in tube end requires a clean, square-cut tube end for proper sealing and retention. Apply thread sealant to the FNPTF port connection in accordance with applicable codes and the fitting manufacturer guidelines.
