Seals and Gaskets
Stop leaks and odors for good with genuine Dometic 4300/4400 Series seals and gaskets. A worn flush ball seal or base gasket is one of the most common causes of electric toilet leaks, bad smells, and water loss around the base — and one of the easiest, most affordable fixes. Shop replacement flush ball seals, base gaskets, and O-rings built specifically for Dometic 4300, 4400 (and compatible 4600, 4700, 4800) series toilets, so you can stop a leaky or smelly toilet in your motorhome, bus conversion, or mobile restroom without replacing the whole unit.
