Nibco, Inc. 60722 1/2" Copper 90 Degree Long Radius Elbow

1/2-Inch Long-Radius Copper Elbow

This 90-degree long-radius elbow connects two 1/2-inch copper tubes in sweat-fitting installations. It is suited for potable water, air and gas lines where a smooth directional change is required. The wrot copper construction meets standard plumbing requirements for residential and light-commercial systems. Builders who need a different angle or a reducing fitting will need another part.

577 PSI at 200 Degrees F Pressure Limit

The fitting is rated for a maximum operating pressure of 577 psi when the fluid temperature is 200 degrees Fahrenheit. Higher temperatures reduce the allowable pressure, so the installer must verify the system design stays within the published curve. The long-radius geometry reduces turbulence but does not change the pressure-temperature boundary. Systems that exceed this envelope require a different class of fitting.

400 Degrees F Temperature Ceiling

The copper alloy withstands continuous exposure up to 400 degrees Fahrenheit, providing headroom for hot-water heating and low-pressure steam applications. Above this temperature the material strength drops sharply and the joint integrity cannot be assured. The elbow handles typical hydronic loops comfortably but is not rated for high-temperature steam or industrial process heat beyond the stated limit.
