If you’re tired of dealing with troublesome toilet seals and want a quick and effective solution, this one is definitely worth it.Highly recommend the RV Toilet Seal for its ease of installation and stellar performance!

This seal was too large in both width and thickness to fit properly for the Dometic 310 RV toilet. for it to actually fit tight on the floor flange. I have had to order a replacement from Dometic. This has delayed my repair by more than a week. I should have listened to another reviewer who had the same problem.

This seal looks to be better than the original. It's a bit thicker and plyable. I have a 310 version toilet and it fits great
