Dometic 385310063 Floor Flange Seal

OEM Toilet Base Seal for Traveler Lite 111, Traveler 510H/511H, 510PS/511PS, 510+, and VacuFlush Models

Ensure a secure, leak-free toilet installation with the Dometic 385310063 Floor Flange Seal—the genuine OEM base gasket used across multiple Traveler Lite, Traveler, and VacuFlush toilets. This durable rubber seal creates the watertight and odor-tight barrier between the toilet and the floor flange, preventing leaks, rocking, and sewage odors from escaping into your RV or marine environment.

If your toilet wobbles, leaks at the base, or emits odors despite cleaning, replacing the flange gasket is the most reliable fix.

Frequently Asked Questions

Q: Should this seal be replaced every time the toilet is removed?
Yes. Old seals compress and won’t reseal properly once disturbed.

Q: Will this fit VacuFlush 500 or 700 series?
Some VacuFlush models use different seals—verify your model’s requirement.

Q: Is this an OEM part?
Yes—this is the genuine Dometic/Sealand replacement seal.

Q: My toilet smells even after cleaning—could this fix it?
Yes. A degraded flange seal is one of the most common causes of odor at the base.
