Excellent product with high quality silicone and thick! I needed to use these to attach a bidet toilet seat that did not come with all of the parts that it was supposed to. This plus a few other parts were able to add the friction that was needed to keep it in place, mostly… still working on that project to perfect it.But these gaskets are great and I’m sure they would also work well for their normal intended purpose. Recommend.

This is a great product. They were easy to install, and so far they have resolved the issue. Leak is finally stopped! Great value for money. Would highly recommend!
