Norgren 120200400 Push-to-connect Union Straight Fitting

Product Description

The NORGREN 120200400 is a Pneufit push-to-connect straight union tube fitting designed for tube-to-tube connections in pneumatic and fluid systems. Constructed from nickel-plated brass, it accepts 1/4 inch OD tubing on both ends and requires no tools for assembly — tubing inserts and locks in place with a single push. Rated to 260 psi maximum working pressure, the fitting operates across a temperature range of -4 degrees F to 175 degrees F. It also carries a vacuum rating of 29.5 in-Hg, making it suitable for both pressure and vacuum circuit applications. HVAC technicians, pneumatic controls installers, and industrial maintenance trades use this fitting for fast, reliable inline connections.

This fitting is used in pneumatic control lines, compressed air distribution, and light-duty fluid transfer applications where a quick, leak-free inline union is needed. Its straight configuration makes it a direct in-line coupler for joining two runs of 1/4 inch OD tubing without additional fittings or adapters. Typical installations include control panel pneumatic circuits, HVAC pneumatic actuator lines, and instrumentation tubing runs in both light commercial and industrial environments.

Key Features

• Push-to-connect design — no tools required for tube insertion or release
• Rated to 260 psi maximum working pressure
• Vacuum rated to 29.5 in-Hg for dual pressure/vacuum service
• Nickel-plated brass construction for corrosion resistance and durability
• Wide temperature range: -4 degrees F to 175 degrees F
• Compact 1.28 inch overall length for tight installation spaces

Compatibility

Designed for use with 1/4 inch OD tubing in pneumatic and low-pressure fluid systems. Suitable as an OEM-style or replacement straight union fitting in applications requiring a Pneufit-series push-to-connect connection.

Installation Notes

Installation is performed by pneumatic controls technicians or qualified HVAC and instrumentation trades. Depressurize and isolate the pneumatic circuit completely before disconnecting or installing any fittings. Ensure tubing is cut cleanly and squarely with a tubing cutter — deformed or burred tube ends can compromise the push-to-connect seal. Verify that tubing OD is within tolerance before insertion to ensure the collet grips correctly.
