RV toilet seal for a Dometic toilet worked well to replace the seal on the toilet. Easy to install. It helped to eliminate the smell coming up from the black tank. Well worth the price.

I installed these in our fifth wheel camper as the old one was pretty old. The first one didn’t seal for some reason I slowly leaked. These are easy enough to install so I put the other one in and it worked great. The dealer wanted $50 for just one of these so these are a great value and seem to be just as well made as OEM.
