These fit our fifth wheel PERFECTLY! Easily to install, I would recommend watching some YouTube videos if you have never replaced this though as it doesn’t come with instructions which was fine but watch a couple bc some are way easier than others! Great product though!!

Perfect fit for Dometic 310 RV toilet. Installation goes as described, a little awkward to get it started in the groove, but just have faith and follow directions. Installs with the ball in position, solving any worry about it slipping out of your hands and down the black hole. Keep an extra on hand.

Changed out using this gasket, works perfect and stopped the odor coming back through the RV toilet

It's the right diameter but the thickness is way different from the original it's about 1/3 as thick so it does not seal. Does not apply enough pressure to make a firm seal looks like it would work but it does not. Would be better off with a rubber band.

Installs easily if lever is left closed after removing old seal. Worked great!

My wife and I replaced our Dometic 300 with the upgraded 310 model, and especially for toilet functions, we like to keep extra parts in our camper in case the worst happens. We have not yet had a problem, but we have this as our backup. It seems to be durably made with dependable rubber. Recommended for Dometic model RV toilet systems.
