I had a cheaper plug from Menards that didn't hold up very well and ended up having sewage come back up in my basement. I bought this one as a replacement to plug the hole in my basement and it is rock solid 10 out of 10.

Have this capping a toilet drain pending a bathroom remodel, to keep the sewer gas from coming into the house. Fits perfect, seals well. Good price for what it is.

While this product's intended use is for capping a PVC plumbing drain pipe for testing and temporary capping, I used it to seal a three inch stainless steel port I installed as a pass-through for my portable generator's power line. Keeps the weather out when the port is not in use and it's easy to install/remove. I've now used it four (4) times since we have been dealing with power outages caused by winter weather - it's doing exactly what I need it to do! If it's working for me in this alternative use, I am sure it would fill it's intended use(s) just as well. I recommend this item without reservation in terms of it's quality and usefulness. The only ding it got in my review is 'value for money'; for the components and simple design it has, it should have been a bit cheaper to purchase through Amazon than what I paid for it.

Missing a fuel cap on your military surplus HMMWV? Look no further. Unlike other drain caps that need to integrate venting, the HMMWV vents through the intake and requires a complete seal at the drain cap to maintain its ability to ford water up to 5 feet. Works like a charm.

I use these to seal 3" pvc tubes. They cover a wide range of diameters and seal completely without a ton of effort. The red color is very noticeable and that's what you want. The metal hardware is very good quality and the body and o-ring are very durable. The only other thing you would want is a reasonable price and it is.

I opened the cap of my basement cleanout to find that it was missing the plug that is supposed to be there to seal it. Instead, someone had stuffed a large amount of plastic sheeting down it instead - not a good solution.Popped this into the cleanout, turned the large oversized wing nut easily by hand to tighten down and now I feel way more confident that sewer gasses aren't going to be leaking out. It's a simple little thing, but it's made well and I expect it to last forever.
