Connection Details

The Vintage CC43252X is a straight shut-off valve designed for bath faucet installations. It features a 1/2 inch sweat inlet and a 3/8 inch O.D. compression outlet for connecting supply lines. This new component is intended for plumbing repairs or new fixture installations where a direct flow path is required.

Installer Suitability

This valve suits plumbers and homeowners completing copper pipe connections that require a straight-through shut-off point. It is not for installations needing an angled body to navigate tight clearances behind fixtures. Buyers requiring a different inlet connection type or outlet size should look at alternative valve configurations.

Questions about this item

What pipe sizes does the 1/2" sweat and 3/8" O.D. compression connection require?

The valve body accepts a 1/2" copper pipe for sweat soldering on one end and a 3/8" outside-diameter supply tube for compression fitting on the other.

Which installation step is most often missed when fitting the compression side?

Slip the compression nut and ferrule onto the supply tube before inserting it into the valve body, then tighten the nut without over-compressing the ferrule.

How often should the internal seat washer be inspected or replaced on this straight shut-off valve?

Check the seat washer annually for hardening or wear; replace it if dripping appears at the outlet when the handle is fully closed.
