Fits old Thetford toilet easy replace.
My toilet was smelling bad and figured it was the flange seal. My old one was worn out and distorted allowing gases front black tank to seep into the camper. These are super easy to replace so donโt feel intimidated not a dirty job.1. Turn off the water and pump to your rig2. Turn on few faucets to relieve the pressure in the lines3. Hold the foot pedal down for a few seconds to dump all the water4. Remove front cover around foot pedal โit just snaps onโ5. Unscrew water line on back of toilet mine just threads on by hand no tools needed. (Recommend getting a towel around water line, little excess water in the line will probably drip out. Itโs clean water donโt worry comes from same place your sink does)6. On each side of the toilet these is a nut you need to remove I think was 9/16 I just used adjustable wrench.7. After removing nuts and disconnecting water line your toilet can be lifted off. I laid down a trash bag on the floor to set it on.8. Replace gasket, old one will be either stuck to floor flange or on bottom of the toilet. Place the new one on the bottom of the toilet with the tapered part facing down towards the floor.9. Set toilet back in place will be little tricky to line up the holes for the bolts. Ensure the toilet is centered on the hole and sits flush and straight.10. Tighten down the two nuts. Donโt over tighten them, the flange and the toilet is plastic and will crack. Just snug is good.11. Reconnect water line and turn water back on and your done. No more sewer smell.

Keep a Spare
Thetford Closet Flange Seal works great with the Thetford Aqua Magic II in my camper . Keep a spare on hand just incase
User
Great Seal
I will be honest, I returned this one because one came with the new toilet that I had purchased. The exact same seal came with the toilet and that seal is tight. I do not foresee any leaks happening with this. The quality of the materials is good and the price is good for what you are purchasing it for.

Perfect fit.
What can I say, it fit?

Stink gone
This is the one you want that goes between the toilet and the flange. This is not the one that goes between the tank and the floor. If your toilet is leaking at the base, use this one first
