RV Toilet Seal Fit for Dometic 300/310/320 Toilet, 385311652 RV Toilet Seal Replacement Parts Fit for Dometic RV Toilet Seal

The product fits perfect, the quality is very good.

I bought this for my mother in law's RV. It fits like a glove and works great. I wasn't really sure what to expect, but it comes with all of the necessary hardware as well. It seems sturdy and durable.

The main seal is practically impossible to correctly install. It's because it's the same width all the way around yet the area it has to seal has two sides, opposite each other that the seal won't slide into because it's too big to fit. So I watched and You Tube video and it showed that in those areas, you had to compress the gasket with your fingers and force it into that smaller area as best as possible. I did this, and had to be careful mounting the toilet so it didn't come off. So it took a couple times, but installed perfectly.

We were not able to use the the large ring. It was too large for the bottom of the toilet and therefore we could not get the toilet to seal properly and sit firmly on the floor. We had to clean up the old one and put it back on. The small ring worked as promised and the toilet bowl now will hold water, so orders don't come into the bathroom.

Every thing needed to install/reinstall the toilet in an RV. Has everything you need except the toilet.

Perfect to use after you have to pull the RV commode

Seal seems to be made out of good quality rubber! Kit fit as it should.

We had a long time smell issue in the RV. We tried everything to reduce it. From powder to gel, washing the tanks and even used blitch. Nothing helped, NADA!!!Few weeks ago my husband watch a YouTube video and the guy recommended to replace the ball seal and gasket. So far, it seems to work find and no smell issue in the RV.We also found out that Dometic toilet system for RV's have some smell issue.If you run into the same issue we did, that ball seal and also the gasket seal at the bottom might be the solution for you.
