Copper Union for 1/2 in Tubing Systems

This ZORO SELECT sweat fitting union joins 1/2 in copper tubing to a 1/2 in male NPT thread. Cast copper construction handles 722 psi at 100 Degrees F and temperatures up to 400 Degrees F. The straight union shape suits standard plumbing layouts.

Suited for copper pipe transitions to threaded

Installers moving between sweat and threaded connections will find the cup and MNPT ends convenient. The fitting is not for systems exceeding the rated pressure or temperature, nor for non-copper tubing materials.

Rated for 722 psi at 100 Degrees F

The cast copper body provides headroom for typical residential hot and cold water lines. Headroom diminishes as temperatures approach 400 Degrees F, so high-temperature steam or process lines should be evaluated separately.

Questions about this item

What copper tubing size must I already have for the 1/2 in cup end to solder correctly?

The cup end is sized for 1/2 in copper tube with a 5/8 in outer diameter, so you need tubing of that exact size for a proper sweat joint.

Will the 1/2 in MNPT thread mate with the galvanized pipe I am keeping in the wall?

Yes, the male NPT thread follows the standard 1/2 in pipe size, so it will thread into any matching female NPT fitting on your existing galvanized pipe.

How can I verify the union is holding pressure after I solder and thread it in?

Pressurise the system up to the 722 psi rating at 100 °F and check for leaks at both the soldered cup joint and the threaded MNPT connection.
