What Customers Are Saying
The compression cap is a useful and effective product for sealing off water lines, valves, and other plumbing fittings. Many customers found it worked as expected to stop leaks and prepare for home renovations. Using a small washer or Teflon tape helped create a tighter seal. While a few had issues with the fit or experienced minor leaks, the majority found the cap to be a reliable and affordable solution for their plumbing needs.

Would RecommendI needed a block off cap for my hot water line for my new sink. I went to the store and asked for assistance in finding the cap. No one ever came and I searched for 15 minutes until I found it. With it I was able to install my new faucet in my sink.

Ice Maker Water Line Cap
Would RecommendSuccessfully capped the water line for the Ice Maker. In my case the valve was leaking when in the off position, but was not leaking in the on position. Thus I capped it when off, then turned the valve back on as a temporary measure while doing a kitchen renovation.
You will need a washer to cap off line.
Would RecommendWith addition of a washer this works great.
