Norgren C20820500 Union Y Tube Fitting 5/16 in Od

Product Description

The NORGREN C20820500 is a push-to-connect union Y tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from brass, it connects three 5/16-inch OD tubes in a Y configuration without tools — tubing inserts and locks in a single push. The fitting handles pressures up to 150 psi and operates across a temperature range of 0 to 175 degrees F, with a nitrile O-ring providing the primary seal. At 1.71 inches overall length, it fits compact plumbing and instrumentation layouts. Licensed HVAC techs, plumbers, and instrumentation technicians install this type of fitting in compressed-air distribution, control-line plumbing, and process fluid circuits.

This fitting suits residential and light commercial pneumatic control systems, compressed-air branch lines, and fluid distribution circuits where a three-way tube split is needed. The push-to-connect design makes it appropriate for tight spaces where threaded fittings or compression sleeves are impractical. It is commonly used in HVAC pneumatic controls, process instrumentation tubing, and general-purpose compressed-air plumbing operating within its rated temperature and pressure range.

Key Features

• Push-to-connect design — no tools required for tube insertion
• Brass construction for corrosion resistance in air and compatible fluid service
• Nitrile O-ring seal rated for 0 to 175 degrees F service
• Rated to 150 psi maximum working pressure
• Union Y configuration splits one line into two branch connections
• Compact 1.71-inch overall length fits tight plumbing layouts

Compatibility

Designed for use with 5/16-inch OD tubing in push-to-connect pneumatic and fluid-handling systems operating within the rated pressure and temperature limits.

Installation Notes

Shut off and depressurize the system completely before removing or installing any tube fittings. Cut tubing square with a proper tube cutter to ensure a full, leak-free seat against the O-ring. Insert tubing to full depth until it bottoms in the fitting body. Verify the connection is leak-free before returning the system to service — soap-bubble or electronic leak detection is standard practice.
