Plug-In Base O-Ring 385311294 For 4800 Series Vacuflush Heads

Part Number 385311294 (also known as Sealand 600344609, Dometic SKU 9108558743) — Replacement Plug-In Base O-Ring for Dometic Designer Series electronic flush toilet heads.

The plug-in base O-ring is the seal that maintains a vacuum-tight connection between the toilet’s bowl/housing assembly and its base. When this O-ring deteriorates, vacuum leaks at the base of the toilet result in the vacuum generator cycling on more frequently and a loss of the powerful, bowl-clearing flush the VacuFlush system is known for. If your Designer series toilet seems to have a weak flush or the vacuum generator is running constantly, this O-ring is a critical component to inspect.

• Fits: Dometic VacuFlush Designer Series electronic flush toilet heads
• Restores vacuum integrity at the bowl-to-base connection

Installation tip: Before installing the new O-ring, clean the seating groove thoroughly to remove any residue from the old seal. Lubricate with a food-safe silicone grease such as Super Lube® (SKU 82340) for easier seating and longer seal life. Do not use petroleum-based lubricants on rubber seals.
