Straight Shut-off Valve

This Vintage CC43251 valve controls water flow at a bath faucet supply line. It connects a 1/2 inch sweat copper inlet to a 3/8 inch O.D. compression outlet. The straight body suits in-line pipe runs. Plumbers and DIY installers use it for new or replacement fixture hookups.

Prop 65 Compliance Notice

California Proposition 65 warnings apply to this product. The notices state it contains chemicals known to cause cancer and birth defects or other reproductive harm. These labels inform safe handling and installation practices. No bundled accessories or software change the valve function.

1/2 Inch Sweat By 3/8 Inch Compression

The inlet requires soldering to 1/2 inch copper tubing while the outlet accepts 3/8 inch O.D. supply lines via compression nut. This specific end configuration decides if the valve fits the existing rough-in. Verify both connection types before purchase.

Questions about this item

Will the 1/2" sweat connection or the 3/8" O.D. compression fitting need replacement first on the CC43251 valve?

Both connections are integral brass components; the compression ferrule may need replacement if the supply line is removed and re-seated, while the sweat joint remains permanent once soldered.

What pressure or temperature limit will be reached first during continuous operation?

The valve is rated for standard residential plumbing pressures and temperatures; the compression seal typically reaches its limit before the soldered joint under sustained high-temperature cycling.

Does the CC43251 generate noise, heat or draw power when left open all day?

No, it is a manual quarter-turn shut-off valve with no moving electrical parts, so it produces no noise, no heat and consumes no power during continuous operation.
