Norgren 94450704M Bulkhead Union Fitting 1/4 in Od Brass

Product Description

The NORGREN 94450704M is a push-to-connect bulkhead union tube fitting designed for tube-to-tube connections in pneumatic and fluid control systems. Constructed from brass, it accepts 1/4 inch outside diameter tubing on both ends and supports a maximum working pressure of 150 psi. The bulkhead configuration allows the fitting to pass through a panel or enclosure wall, securing with a locknut to create a sealed, through-panel connection. Buna O-rings provide a reliable seal across a working temperature range of -40 degrees F to 212 degrees F. Licensed HVAC, plumbing, and industrial service technicians install this type of fitting in compressed air lines, instrumentation tubing, and fluid distribution manifolds.

This fitting is suited for residential and light commercial pneumatic systems, compressed air distribution panels, and instrumentation enclosures where a tube line must pass through a bulkhead or panel wall. The push-to-connect design eliminates the need for ferrules or compression nuts, allowing fast, tool-free tube insertion and secure retention. It is commonly found in HVAC control panels, refrigeration equipment cabinets, and industrial automation enclosures where organized tube routing through partitions is required.

Key Features

• Push-to-connect design accepts 1/4 inch OD tubing on both ends without tools or ferrules
• Bulkhead configuration for through-panel tube routing in enclosures and control panels
• Brass construction for corrosion resistance in pneumatic and fluid service
• Rated to 150 psi maximum working pressure
• Buna O-rings seal reliably from -40 degrees F to 212 degrees F
• SAE 630103 thread type for standardized panel mounting

Compatibility

Designed as an OEM-style push-to-connect bulkhead union for systems using 1/4 inch OD tubing in pneumatic, compressed air, or instrumentation applications.

Installation Notes

Installation should be performed by a qualified technician. Depressurize and isolate the tubing circuit completely before removing or installing any fitting. Ensure the panel or bulkhead material thickness is compatible with the fitting body and locknut engagement length before mounting. Tube ends should be cut cleanly and squarely, deburred, and fully inserted to the fitting stop to ensure a leak-free connection.
