What Customers Are Saying

The compression cap appears to be a generally 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 facilitate home renovation projects, though some noted using a small washer or Teflon tape helped create a tighter seal. While a few had issues with the cap not fitting properly or leaking, the majority reported it as a reliable and versatile solution for various plumbing needs.

Does exactly as it should!

Fit where it was needed! Capped off the valve where the dishwasher water inlet line would connect.

costs a lot but Lowes has it

Would Recommend

I remember when they were about 89 cents and now they are about $3.50 but at least Lowes has the stuff I need even if I have to pay through the nose...not Lowe's fault.

Cumbersome review process for a simple item

Would Recommend

I was going to write a glowing review about how this simple product does the job it was intended to do without detracting from the aesthetics of the leaky bidet that I used it on. However, I have never been asked to agree to terms and conditions in order to leave a product review - so I will say that while the product does what I bought it to do the review process is unnecessarily cumbersome.
