Norgren 120370712 Push-to-connect Union 1/2 in Od

Product Description

The NORGREN 120370712 is a Pneufit push-to-connect union fitting designed for tube-to-tube connections in pneumatic plumbing systems. It accepts 1/2 inch outside diameter tubing on both ends, allowing a tool-free, push-in connection that holds secure under pressure. Constructed from nickel-plated brass, this union is rated for a maximum working pressure of 260 psi and operates across a temperature range of 0 to 175 degrees F. With an overall length of approximately 1.98 inches (50.3 mm), it is a compact, inline solution for joining two runs of pneumatic tubing. Licensed HVAC technicians, plumbers, and pneumatic system technicians are the typical installers.

This fitting is suited for compressed air and pneumatic control lines in both light industrial and commercial applications. It functions as an inline union where two sections of 1/2 inch OD tubing must be joined without tools, making it practical for equipment panels, air supply manifolds, and field repairs where quick reconnection is required. The vacuum rating of 29.5 in-Hg also makes it usable in light vacuum service applications. Its nickel-plated brass construction resists corrosion in moderate environments.

Compatibility

Designed as an OEM-style push-to-connect union for pneumatic tubing systems using 1/2 inch outside diameter tube. Verify tube OD and working pressure requirements before installation.

Installation Notes

Installation is performed by licensed HVAC technicians or industrial pneumatic system technicians. Depressurize and lock out the air supply line completely before removing or installing any fittings. Ensure tubing ends are cut square and deburred before insertion to achieve a leak-free seal. After pressurizing the system, verify the connection with a leak detection solution before returning to service.
