Flow Stops for Copper Tubing
- For Use With: Water
- Tubing: Use with Copper
Use these temporary flow stops to block water from an area that's being soldered. Commonly used on copper tubing, they allow you to make repairs without waiting for your line to drain. To use, shut off the main supply line, insert the flow stop through the tube you want to repair, and turn the handle to tighten the hex nut. The nut compresses the rubber gasket against the inside of the tube to block the flow so you can immediately solder the damaged area.
