Works perfect, saved a bunch of money compared to what they charge at the local camper store.

Replaces the bowl seal in most Dometic toilet models even though it doesn't look exactly like the original. Watch the Youtube videos for instructions on various models to figure out which model you have, take your time and install is easy

Great replacement for the old style. Reduces the possibility of leakage with the new design

good item

Easy to replace, fit tight and arrived on time…. Great seal problem solved.

Can I even return this? Will they accept it after it’s been placed on my toilet?! I doubt it. Looks like I’ll hate to take my loss. Does not fit the Dometic 210. Hole in rubber gasket is too small. Raised center portion of rubber gasket is too big in diameter. Plastic plate is too big for toilet. Cleaned my old gasket and put some plumbers grease on it. Bowl leaks worse than before. Looks like OEM is going to be the only route. Don’t buy this and waste your time. It doesn’t fit.

I didn't know I needed this until I replaced the floor seal.Go ahead and order this anytime you disassemble your RV or Marine toilet. It's not expensive and will save you from future 'surprises' during your travels.

it was just a fraction (1/32" or so) larger than what it should have been.had to file it down so that it would fit properly.after getting it to fit, toilet seems to work properly and will now hold water in the bowl.
