Vintage CC44451X straight shut-off valve

The Vintage CC44451X is a straight shut-off valve with 5/8 inch OD compression on one side and 1/2 inch OD compression on the other. It is designed for use in bath faucet plumbing repairs or installations. The valve provides a simple on-off control for water supply lines in residential bathrooms. This component suits DIYers and plumbers replacing a worn valve on existing supply stops.

Sustained operation with compression fittings

Under continuous household water pressure the compression joints maintain a seal without the need for soldering. The straight body allows inline installation where the supply line runs directly to the fixture. No moving parts beyond the stem reduce wear during repeated daily cycles. The valve body handles standard residential pressure ranges without degradation over time.

Replaces worn supply stops on similar tubing

This valve replaces an existing straight stop that has begun to leak or seize on 5/8 inch and 1/2 inch OD tubing. The upgrade is worth it when the old valve no longer shuts off cleanly or shows corrosion on the stem. It is not suited for systems requiring sweat or push-fit connections, nor for supply lines with different outside diameters. Buyers needing angled stops or different port sizes must select another model.

Questions about this item

Does the Vintage CC44451X valve generate heat or noise during continuous water flow?

The Vintage CC44451X is a passive mechanical shut-off valve with no moving electrical parts, so it produces no operational noise or heat during continuous water flow.

What pipe fittings must I already have to install the 5/8 OD and 1/2 OD compression ends?

You need existing copper or compatible tubing with 5/8-inch and 1/2-inch outside diameters, plus compression nuts and ferrules sized for those diameters, to connect the valve's compression ends.

Will this straight shut-off valve work with older iron or galvanised supply lines in a vintage bathroom?

The compression ends are designed for copper tubing; connecting to iron or galvanised pipe requires appropriate transition adapters not included with the Vintage CC44451X.
