Thetford Titan® Sewer Fitting Seals

Replacement Seals for RV Sewer Hose & Adapter Connections

Thetford Titan® Sewer Fitting Seals are genuine replacement seals designed to restore leak-free performance to RV sewer hoses, adapters, and fittings that use bayonet-style connections. Made by Thetford, these seals help ensure a tight, reliable connection at the dump station while reducing drips, odors, and messy cleanups.

Over time, sewer seals can dry out, crack, or lose elasticity, leading to leaks and poor connections. Replacing worn seals with Titan sewer fitting seals is a quick, inexpensive way to extend the life of your sewer equipment and maintain a clean, sanitary hookup for travel trailers, fifth wheels, and motorhomes.
