Review on 🚽 Mission Automotive Dometic-Compatible Flush Ball Seal Kit for 300/310/320 RV Toilets - Replaces Parts Number 385311658 - High-Quality Replacement Gasket by John Hall

This gasket didn't fit perfectly on my Dometic model 310. I bought this gasket because my RV toilet wasn't holding water, it had a slow leak. I removed the old gasket and replaced it with a new gasket and there was a small gap in it. I lubricated the gasket, cleaned the toilet and orifice thoroughly to make sure there was no excess residue and the gasket just wasn't a perfect fit. When I placed the gasket flat side down it snapped into place but stayed put. I put the plunger back in and it wasn't even around the entire lip or ball. I took the old seal and compared the two and the old seal was slightly larger and more solid. I just cleaned the old gasket, removed any residue that was on it and put it back in place. This new seal did not fit my particular toilet but I will keep it because we can use it for something else or in our next RV. *** If this review helped you a little, please let Revane know with a Helpful Click.
