Norgren 120290300 Bulkhead Union Fitting 3/16 in Od

Product Description

The NORGREN 120290300 is a Pneufit straight bulkhead union fitting designed for push-to-connect tube-to-tube connections in pneumatic systems. It accepts 3/16 inch OD tubing on both ends and threads into a panel or bulkhead using an M12 x 1 thread, allowing a pneumatic line to pass cleanly through a wall or enclosure without additional hardware. The body is nickel-plated brass, rated for a maximum working pressure of 260 psi and a vacuum rating of 29.5 in-Hg. Licensed HVAC technicians, pneumatic system integrators, and industrial maintenance technicians install this fitting in compressed air and general-purpose pneumatic circuits.

This fitting is suited for general-purpose pneumatic applications where a tube line must route through a panel, enclosure, or bulkhead. Its straight configuration makes it appropriate for inline pass-through installations in both light industrial and commercial equipment. The operating temperature range of -4 degrees F to 175 degrees F covers a wide range of indoor service environments. The push-to-connect design allows for fast tube insertion and removal without tools, reducing installation time in high-volume or service applications.

• Nickel-plated brass body provides corrosion resistance suitable for compressed air service
• Rated to 260 psi maximum working pressure
• Vacuum-capable to 29.5 in-Hg for vacuum circuit applications
• M12 x 1 thread for secure bulkhead panel mounting
• Operating temperature range: -4 degrees F to 175 degrees F

Compatibility

Designed for general-purpose pneumatic tube-to-tube bulkhead connections using 3/16 inch OD tubing. Compatible with standard compressed air and vacuum lines operating within the rated pressure and temperature limits of this fitting.

Installation Notes

Installation is typically performed by pneumatic system technicians or industrial maintenance professionals. Depressurize and lock out the pneumatic circuit before removing or installing any fittings. Ensure the panel or bulkhead material is rated to support the M12 x 1 threaded connection and that the hole diameter is appropriate for the fitting body. Cut tubing squarely and deburr before inserting into the push-to-connect ends to ensure a reliable seal.
