Norgren 120400500 Union Elbow Fitting 5/16 in Od

Product Description

The NORGREN 120400500 is a Pneufit push-to-connect union elbow tube fitting designed for pneumatic and general-purpose fluid handling systems. It connects tube to tube in a 90-degree elbow configuration without the need for tools or thread sealants. The fitting accepts 5/16-inch outside diameter tubing and is constructed from nickel-plated brass, providing corrosion resistance in demanding service environments. It is rated for a maximum working pressure of 260 psi and carries a vacuum rating of 29.5 in-Hg, making it suitable for both pressure and vacuum lines. HVAC technicians, plumbers, and industrial maintenance professionals install this fitting in compressed air, pneumatic control, and light fluid distribution applications.

This fitting is intended for general-purpose pneumatic and fluid system use. It performs across a wide service temperature range, from -4 degrees F to 175 degrees F, covering most indoor and light-duty outdoor installations. The push-to-connect design allows fast field connections and reconnections without special tooling, reducing installation time on compressed air lines, pneumatic actuator circuits, and control tubing runs in both residential and commercial mechanical systems.

Key Features

• Push-to-connect design — no tools or thread sealant required for tube insertion
• 5/16-inch OD tube acceptance for standard pneumatic tubing
• Nickel-plated brass construction for corrosion resistance and long service life
• 260 psi maximum working pressure rating
• 29.5 in-Hg vacuum rating supports vacuum line applications

Compatibility

Designed for general-purpose pneumatic and fluid handling systems using 5/16-inch OD tubing. Suitable for compressed air, vacuum, and light-duty fluid lines where push-to-connect tube fittings are specified.

Installation Notes

Depressurize and isolate the pneumatic or fluid line fully before disconnecting or installing any tube fitting. Confirm tubing is cut cleanly and squarely, with no burrs, before inserting into the fitting to ensure a proper seal. This fitting is installed by HVAC technicians, industrial mechanics, and plumbers working on pneumatic control and distribution systems. Follow applicable system codes and the equipment manufacturer's specifications for tubing material and pressure ratings.
