1/2" Sweat Straight Stop Valve

This 1/2" sweat straight stop valve with 3/8" O.D. compression outlet is built for residential plumbing shut-off points. It suits installers and homeowners who need a reliable quarter-turn or multi-turn stop at fixture supply lines.

Installation notes and common issues

The sweat inlet requires copper pipe preparation and soldering skill; ensure the pipe is clean and fluxed before heating. The compression outlet needs proper ferrule seating and nut torque to prevent weeping. Over-tightening the compression nut or insufficient solder flow are the typical causes of leaks.

Pre-order checks

Verify that your supply line is 1/2" copper suitable for sweat connection and that the fixture or riser accepts a 3/8" O.D. compression fitting. Confirm local code requirements for shut-off valve placement and any lead-free mandates. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I confirm the straight stop valve is leak free after installation?

Turn the water supply back on and check the sweat and compression connections for drips; the easy to remove handle should operate smoothly to shut off flow at the source.

What comes with the CC43258K valve and what must be purchased separately?

The valve itself is supplied; pipe solder and compression fittings for the 1/2" sweat and 3/8" O.D. connections are not included.

Which finish option should I choose for corrosion resistance?

All available finishes on this model are corrosion resistant, so select the one that matches your existing fixtures.
