The Dometic / Sealand Bellows O-Ring Kit 385310151 is essential for maintaining the efficiency and performance of your marine sanitation system. Designed for use with various Dometic and Vacuflush models, this kit ensures a tight seal to prevent leaks. Regular replacement of O-rings helps maintain optimal functionality and prolongs the life of your equipment.
The Vacuflush Replacement Bellows Kit is compatible with S-Series Vacuum Pump, T-Series Discharge Pump, VGII, VGIII, and J-Series Vacuum Generator. These is the latest improved design which can be identified by the gray-colored shaft and puck. This version is the only one currently made by Dometic.
