Dometic 385311111 1-1/2 Inch Sealing Grommet - Replaces Sealand 600342932 - Vacuflush Toilet Inlet Elbow Seal

The Dometic 385311111 Sealing Grommet is a 1-1/2 inch inner diameter replacement seal designed for the inlet elbow fittings on Dometic and Sealand vacuum holding tanks. It is used on Dometic Sealand VacuFlush VHT toilets, where it seals the connection point where the inlet elbow meets the vacuum holding tank, preventing air and water leaks that can compromise vacuum pressure in the system. Over time, rubber grommets in marine sanitation systems lose their seal from repeated flush cycles and exposure to holding tank contents, and a worn or cracked grommet is a common cause of a vacuum toilet system that will not hold vacuum or that leaks at the tank inlet fitting. Replacing this grommet restores a tight seal at the inlet elbow connection without requiring replacement of the entire vacuum holding tank or elbow fitting. It is a genuine Dometic spare part and serves as the direct OEM replacement for the earlier Sealand-branded part. The grommet measures 6 inches by 6 inches by 1 inch as packaged and is intended as a straightforward, single-component repair item for technicians and boat owners maintaining a Dometic or Sealand vacuum sanitation system.
