Finally found a toilet ring.that fits right. I've been to all the upper end home stores and every ring I bought was a pain to form fit amd either disnt last or I had to reset. I don't know the longevity of these yet...but they were the easiest and best fit I've found in years

Toilet was slowly leaking into the bowl. This solves the problem. Make sure you get it in the groove and spin it a couple times before filling with water

I initially repaired my Mansfield toilet task seal with the rubber gasket version of this part, but the slow slight leak wouldn't stop. I repositioned, checked installation, but I was unsuccessful at stopping the leaking into the bowl.Then, I bought the silicone version of the part. It's fixed now. The silicone is softer and more pliable. The leaked has stopped. The upgrade to the higher quality material is worth the extra couple bucks.The only reason I gave this 4 stars instead of five is that it's made in China and not the USA.

The process great. The product looked exact. But when I put in the seal it “puckered” underwater. Went to hardware and bought the brand name which was one seal for the same price. Put it on and no problems. I’m assuming it puckered because it’s silicone not rubber.

My house has all Mansfield toilets. At first I didn't like them. Once I found out how easy it is to replace this gasket, I really like them now. Much easier then any other toilet I have had. NOTE: read the directions closely. If you don't get the seal in the correct groove, it will still leak. Changing one of these seals only takes five minutes or less.

Surprisingly, my local big box hardware stores didn’t have any of these in stock. Ended up picking some up from Ace after placing the Amazon order but decided not to cancel the order and just having a couple in case of emergency. Good thing, the one from Ace didn’t fit well at all and actually still left the toilet with a small leak. Nothing major, but still not sealed off completely. Decided to use the ones off Amazon and it the leak was solved! Comparing them side to side you can see the difference in thickness and fit.

So, after calling my local plumbing supply company (which provided the Mansfield toilets in our home) and getting only a grunt in response to asking why they were flushing so hard after 7 years of use, I did some online research and found that the cause could likely be the flush tower sticking to the valve seal. That made sense to me, so I ordered these up. They take about 5 minutes to install after popping off the old ones and cleaning up the inevitable black mold in the tank, and the flush is back to like-new again! I can't comment on logevity at this point, but even if they aren't long-lived, I'm sure they will last long enough to justify the cost. An easy and cheap fix. Do a web search for "replace flush seal on Mansfield toilets" or something similar for specific installation instructions. Anyone can do it.

My toilet inner parts broke and were not available locally; we thought we would have to buy an entirely new toilet. Replacement parts were available from Amazon. we ordered and they arrived promptly, were easy to install and we saved a lot of money. Very satisfied.

Arrived very fast. They weren't wide enough for my system, but two together seem to be doing the trick.
