Thetford Flush door 5 & Battery Box Door Seal

The Thetford Flush Door 5 Battery Box Door Seal is a genuine replacement rubber gasket designed for Thetford Flush Service Door 5 (FD5) battery box and locker doors fitted to many caravans, campervans, and motorhomes.

This durable rubber seal fits around the door frame to create a tight seal when the service door is closed, helping prevent water, dust, and road debris from entering the battery compartment or storage locker. Maintaining a good door seal also helps protect electrical components and equipment stored inside the locker.

Over time, service door seals can become brittle, flattened, or damaged due to weather exposure and repeated opening and closing. Replacing the seal restores proper weather protection and helps maintain the integrity of your caravan’s external storage compartments.

Designed specifically for Thetford Flush Door 5 units, this replacement part provides accurate fitment and reliable long-term performance.
