Dometic 385316140 Toilet Bowl Seal Kit with Holes for Vacuflush and Traveler Toilets (2000 and Older)

The Dometic 385316140 Toilet Bowl Seal Kit with Holes is a replacement seal set for Dometic/Sealand foot-pedal toilets, designed to restore a watertight connection between the toilet bowl and its base. The kit includes the ball seal and the bowl-to-base seal with overflow holes, the two components that most commonly wear out and cause leaks or loss of vacuum on these toilets over time. It is built to fit 2000 and older Dometic/Sealand Vacuflush and Traveler model toilets, including EcoVac 157, 158, and 159 models. Because these seals are wear items exposed to constant moisture and vacuum cycling, Dometic recommends replacing them every three years as routine maintenance to keep the toilet flushing properly and to prevent water intrusion around the base. This kit directly replaces Sealand part number 316140, making it a straightforward match for owners who need to service an existing unit without hunting down obsolete part numbers. The seal kit is finished in black plastic construction sized to fit the original base and bowl mounting points, so no cutting or modification is required during installation. It is a maintenance-focused kit rather than a full toilet rebuild, intended for boat owners performing scheduled upkeep or troubleshooting a leaking base seam on a compatible Dometic/Sealand toilet.
