1" - 1/2" Copper Coupling

About this item

A 1 x 1/2 inch copper reducing coupling steps a 1" copper line straight down to 1/2" in a single in-line fitting. This listing is for one new piece.

Do I need a 1 x 1/2 copper reducing coupling or a bushing?

A reducing coupling joins two tubes of different sizes directly. A bushing fits inside another fitting. If you're joining 1" tube to 1/2" tube end to end, the coupling is the simpler choice.

• The title doesn't give the joining method. Check the photos for sweat cups on both ends.
• Dry-fit both tubes before you heat anything.
• A big step-down can reduce flow to fixtures further down the line, so size the branch for what it feeds.
• Follow local code when changing supply lines.
