Seal Fits Perfectly! Simple to Install.
This seal fit perfectly and was simple to install. The seal is made of good quality material and there is no guess work for how the seal is installed. "This Side Up" is visible on the side that faces up when seal is installed. I used a Thetford seal lubricant to help enhance the seal's effectiveness.

Worked perfectly
Our toilet seal was not holding water. We ordered this product and my husband replaced it. He also put a little cooking oil in the bowl to lube the seal. It works and now holds water in the bowl just as it should. We will now have an extra one if we ever need it too. Easy installation and price was fair, as well. We are happy campers now!

Easy Replacement
My RV toilet was starting to let odors out, so I swapped the seal. The process was easy, taking about 10 minutes. I removed the old one, lubed the new seal with vegetable oil, and installed. When I first tested it, water was leaking through. But that was because I didn't have it seated properly. Once I adjusted it, there were no.more issues and no more odor.

Difficult install but worth it.
It was rather difficult to install. At first I thought it was too big but eventually I got it to fit and it seems to work well. It might even be better than the OEM original because it fits tighter.

Clean area where new seal mounts and don't let seal fall into your black tank
Seal fit as advertised but you have to be careful installing them because you get calcium buildup around the old seal from hard water so you need to scrape that stuff out of where the seal goes

Doesn't seal
Won't seal, I even used plumbers grease to try and help get the seal. It is almost like they are a mm off spec to get a seal. If it was a little deeper/lower on the piece that touches the ball flush valve, it would hold, sadly it isnt. Toilet is 6 months old.

Works but has to be greased every month
We live in an RV full-time and the seal works really well however it has to be re-greased every month or else it squeaks and get stuck. But gets the job done. Worked in my domestic 310

Ok

One of the seals did not fit at all on a 310 model but the second one was really easy to install and fit very well. Only issue is that it does not retain water, toilet drains within 4-5 minutes. Tried to re-install and also tried plumbers grease but no improvement. Was disappointed as the reviews are good, I may have just gotten a few bad ones?

I think the grooves aren’t deep enough for it to slide onto, so it buckles a little and doesn’t seal
