TondiamoFlush Valve Rubber Seal 4 Pack Gasket Replacement Compatible with Mansfield 210 and 211, Toilet Flush Valve Replacement Kit Red RV Toilet Seal Compatible with Mansfield 210 and 211

These do not seal properly. Period. I have two Mansfield toilets and both needed a new gasket. These are not like the OEM or Korky after-market rubber gaskets. These are more of a soft plastic like disc. They would not seal on either of my toilets. I had to get proper ones from the hardware store and now it's too late to return these...

Installed on a Mansfield 1.6 gallon per flush tower. The difficulty of install is getting the the ring to sit well into the groove. The durability is less stiff than the original, allowing these seals to actually dip in a small area. This dip prevented a good seal and allowed the new seal to leak as much as the seal removed. I still had to order and replace the entire flush tower to resolve my leak problem.

It is missing a little tab to grasp with thumb and forefinger that allows you to seat the gasket in the proper position. Other than that, very good sealing ability nice composition.

I was having regular leaking from my flush valve. Took out the old seals with some effort, and put these in. No more leak.

Liked the quantity for the price these are fairly easy to install if you’re careful to guide them in groove when installing
