a bit of work but well worth it.

For Dometic 511+ RV toilet. Difficult part is disassembling the toilet to replace the gaskets. and of course the reassembly. Make sure the holes and notches line up where they should, and the retainer rings are positioned properly and re-clamped properly. Per instructions (third-party online), use plenty of silicon plumbers' grease. The gaskets themselves fit well and seal well. They do their job well. What more can be said?

Excellent replacement for my 2003 Beaver Monterey toilet assembly. Easy to pull out the toilet, easy and simple to replace the old seals with the new ones. Put it all back together and no more rank smell. Product works well.

Fit perfect. Great price. Have to wait and see how long it lllasts

Very easy to install, perfect fitment. I even saved the number from the company so if it happens again , I will know where to get the right replacement gasket set. Got it really quick to.

Quality of material, function and fitting was as good or better than the OEM's that I have previously installed ... no leaks, no odors. Great value. A definite re-order!

This gasket has superseded the old gasket so it would be very helpful to have instructions on which gasket goes on first. FYI….the thin gasket goes on the bottom. I replaced the old gasket on my toilet with this and I had to remove the large plastic ring with the small gasket in the center and then this new two piece gasket installs with the thin one first and the thicker one on top. Great quality but adding instructions for those who use this as the superseded gasket would be perfect. “ Thin gasket goes on the bottom!”

Works for a few months only, then you have to replace it again and again. Not worth the job of replacing it every 10 to 15 months..... Better off buying an OEM product that is going to last 10 to 15 years.
