Copper Reducing Adapter

This copper reducing adapter connects 1/2 inch inner diameter tubing to 1 inch outer diameter piping in residential plumbing systems. The MNPT male thread mates with standard female fittings for a secure joint. It suits installers working on bathware supply lines where a transition between copper pipe sizes is required.

Transparent Copper Construction

The transparent finish lets you visually confirm solder flow and joint integrity during installation. Copper resists corrosion in hot and cold water service and withstands typical household pressure ranges. The reducing C x MNPT configuration means one end slips over tubing while the other threads into a valve or fixture.

California Proposition 65 Notice

This product contains a chemical identified under California Proposition 65 as a potential cause of cancer and reproductive harm. The warning applies to the adapter itself and does not describe a performance limitation of the fitting. Installers should follow local codes and use appropriate personal protection when soldering or handling the component.

Questions about this item

What connection does the 450-781 adapter use and what size does it reduce to?

It provides a copper reducing MNPT connection that steps from a 1/2 inch inner diameter to a 1 inch inner diameter.

What pipe dimensions are required for the 450-781 to fit correctly?

The fitting accepts 5/8 inch outer diameter copper on one end and 1 inch outer diameter on the other.

How is the 450-781 installed and what common step is missed?

Clean both copper ends, apply flux, then sweat the joints; the step often missed is fully seating the pipe before heating.
