BougeRV RV Toilet Seal Flush Ball Seal Replacement RV Accessories Flush Ball Gaskets Compatible for Dometic 300/310/320- Equivalent to Part Number 385311658 (2 Pack)

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!

Fit perfect. Easy to install.

Works as advertised. Easy replacement and has stopped our water leak.

I installed these and still had a small leak. I removed it and purchased one made specifically for my toilet. It works fine.

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.

We bought this for our Dometic 310. After struggling to get it in place it didn’t hold water. I then purchased Dometics original part 385311658. Super easy install and held water immediately. Well worth the extra cost.

Seal is well made and an exact fit for the seal that I replaced. Installation took only a few minutes.

I was going to return these because I couldn’t get a good seal and it was oblong not round. Then I remembered in the Dometic manual about using hot water to recondition the seal. I filled a bowl with hot tap water, put the seal in it and let it soften up a bit. Went right in and sealed perfectly. I then coated it with food grade silicone.
