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.

Keep Turning and its Great

Would Recommend

Used this to cap off a angle stop that both couldn't be desoldiered nor completely shut off. Only thing i will say is keep turning, the seal doesn't seal until it is ratcheted down pretty tight. Im an able bodied 39 year old so it requires some elbow grease.

Didn't mention needing a gasket or "teflon tape"

The cap itself fit, but it leaked and it needed something else to stop that water. I used thread seal tape (sometimes called "teflon tape"), and it was pain to put on in the cramped location. I've since read that a gasket (rubber-like or otherwise) also works. I think at minimum there should be a warning, or maybe it could be packaged with a gasket.
