Copper sweat union for 1/2 in tubing

This straight union joins two 1/2 in copper tubes using cup connections on both ends. Cast copper construction handles a maximum operating pressure of 722 psi at 100 degrees F and temperatures up to 400 degrees F. It suits residential and light-commercial tubing systems where a removable joint is needed.

Installers needing a demountable copper joint

The union allows disassembly without cutting pipe, useful for maintenance or equipment replacement. It is not for press-fit, push-fit or threaded systems, nor for tube sizes other than 1/2 in. Builders who need a permanent soldered coupling or a different diameter should look at other fittings.

Rated for 722 psi at 100 degrees F

The fitting comfortably handles typical domestic water pressures and hot-water temperatures up to 400 degrees F. Headroom diminishes as pressure and temperature approach the rated limits together. Systems exceeding either limit require a higher-rated component.

Questions about this item

What copper tube size must the existing pipework be for the 1/2 in cup connections to fit?

The union accepts 1/2 in copper tube size on both sides, which corresponds to a 5/8 in tube outer diameter.

Will the cast copper union handle the pressure and temperature of my current hot-water circuit?

It is rated for 722 psi at 100 Degrees F and a maximum operating temperature of 400 Degrees F.

How can I confirm the sweat joints are sound after soldering the union in place?

Pressurise the system and inspect each cup joint for leaks; a properly sweated connection will hold the rated pressure without weeping.
