Dealing with a leaky RV toilet or water that won’t stay in the bowl? This replacement seal kit solves both problems with quality parts designed specifically for Thetford Aqua Magic toilets. You get a flush ball seal for water retention, a flange seal to stop leaks and odors at the base, plus four plastic gaskets—everything needed for a complete refresh of your RV toilet’s sealing system.

The flush ball seal uses high-quality silicone rubber that maintains its shape and elasticity over time, ensuring your toilet bowl holds water properly between uses. The flange seal is made from durable foam rubber that creates a tight barrier against leaks and prevents unpleasant odors from escaping around the toilet base. Both materials are built to withstand the unique demands of RV life, including temperature changes and constant movement on the road.

Who Is This For?

This kit is perfect for RV owners with Thetford Aqua Magic Style Plus, Style Lite, Style II, or Residence toilets who are experiencing common seal failures. If you’ve noticed water slowly draining from your bowl, moisture around the toilet base, or sewage odors in your RV bathroom, these are classic signs that your seals need replacement. It’s also smart for anyone doing preventive maintenance—replacing seals before they fail completely saves you from bigger headaches down the road. The straightforward installation makes this accessible even if you’re not particularly handy with RV repairs.
