Norgren C20400500 Union Elbow Tube Fitting 5/16 in Od

Product Description

The NORGREN C20400500 is a push-to-connect union elbow tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from brass, this elbow allows two tube runs to be joined at an angle without threading or soldering, using a simple push-in connection mechanism for fast, tool-free assembly. It supports a maximum working pressure of 150 psi and an operating temperature range of 0 degrees F to 175 degrees F. The fitting is sealed with a nitrile O-ring for dependable leak resistance in general-purpose applications. It measures 1.21 inches in overall length and weighs approximately 0.015 pounds.

This fitting is suited for general-purpose pneumatic plumbing, light hydraulic lines, and instrumentation tubing runs in both commercial and light industrial environments. The 5/16 inch OD tube size makes it compatible with small-bore tubing commonly found in compressed-air distribution, process control panels, and equipment manifolds. HVAC technicians, plumbers, and industrial mechanics frequently use push-to-connect fittings like this one when routing control lines or pneumatic actuator feeds in tight spaces where wrench access is limited.

Key Features

• Push-to-connect design allows tool-free tube insertion and fast field assembly
• Brass body construction provides corrosion resistance and durability in general-purpose service
• Nitrile O-ring seal maintains leak-free performance across the rated pressure range
• Rated to 150 psi maximum working pressure
• Operates from 0 degrees F to 175 degrees F, suitable for a wide range of service conditions
• Compact elbow geometry eases routing in confined installations

Compatibility

Designed as a general-purpose push-to-connect union elbow for 5/16 inch OD tubing in pneumatic and fluid-handling applications.

Installation Notes

Installation requires no special tools — cut tubing cleanly and squarely, then insert fully until the tube seats against the fitting stop. Before servicing or replacing any fitting, depressurize and lock out the pneumatic or fluid line per applicable site safety procedures. Inspect tubing ends for burrs or ovality before insertion, as damaged tube ends can compromise the O-ring seal. Follow applicable codes such as the IPC or manufacturer system guidelines for pressure-rated pneumatic plumbing.
