Plumbing Reducing Coupling

The Legend Valve 450-544 is a copper reducing coupling designed for residential and light-commercial plumbing installations. It joins two pipes of different diameters using a soldered copper-to-copper connection. The fitting is supplied new and intended for potable water or hydronic heating systems where a secure, permanent joint is required.

2 x 1/2 Inch Copper Sweat Fit

The single specification that determines compatibility is the nominal size of 2 inches by 1/2 inch inside diameter with a corresponding outside dimension of 2-1/8 inches by 3/4 inch. Both ends are female sweat sockets so the installer solders the coupling directly onto clean copper tube. No threading, compression rings or push-fit mechanism is present.

Thermal Performance in Hot Water Service

Copper construction conducts heat efficiently so the coupling reaches water temperature quickly and contributes negligible restriction to flow. The metal body does not generate noise and adds no measurable pressure drop in normal domestic hot water or heating circuits. No external power or insulation is required for standard operation.

Questions about this item

What does the 2 x 1/2 inch sizing mean when I install this coupling?

It joins a 2 inch copper pipe to a 1/2 inch copper pipe using sweat connections on both ends.

How does the C x C interface affect the joint I can make?

Both ends are female sweat sockets so you solder copper tube directly into each side without threads or adapters.

What clearance do I need for the 2-1/8 x 3/4 inch outside dimensions?

The body measures 2-1/8 inches by 3/4 inches externally, so allow that space inside the wall or cabinet for the fitting and solder joint.
