after trying 2 other "universal" flappers on our Mansfield toilet this one actually did what it was supposed to do, works like a charm.
Worked perfect! The universal flappers won’t cut it for this particular toilet. The oem flappers are worth buying. Just makes sense easy to install, not running toilet and held up with no issues. Adjusting is easy as well.
Exactly as was expected; works perfectly; takes mere minutes to install!
Fit perfectly and better than any of the "universal" flappers I bought. I wasted a lot of money before I found this one.
Perfect fit, good price & timely delivery. Strongly recommend.
Only works if you have all Mansfield parts. It does leak when used with third party valves, and Korky seems to work best for those situations.
Perfect fit for Mansfield toilet.
excellent product.
Great purchase
This item appeared to be in satisfactory condition but I beleive it was misrepresented by the seller because it was advertised as a universal fit. IT WAS NOT.
I bought the size that said was correct for my toilet and it fit perfectly. Much better than the generic ones you can get a Lowe's or Home Depot
Great product
It is exactly the flapper we needed, could not find locally
Fit perfectly
If you have a Mansfield toilet this is the flapper. Other "universal" brand flappers do not work on Mansfield toilets.
EXCELLENT! Very well made. Top quality original. But beware of the insert (baffle). If it is missing the float will not work. Otherwise it is top notch.
I have a Mansfield toilet that was leaking and it needed a new flapper. Thankfully I found this on Amazon and was spared a lot of headaches in that I didn't have to go the route of trying a "universal flapper" design from a big box store that should work with all toilets. For whatever reason those don't seem to work with Mansfield toilets (from what I've read). This part however worked great and was very simple to install. Would definitely recommend if you have a Mansfield toilet.
If you have a Mansfield toilet, you MUST use Mansfield flapper valves or your toilet will leak. Here's why. The mounting brackets used in Mansfield toilets have different sized mounting brackets for those valves. One is significantly larger than the other. All of the other after market replacement flappers (e.g. Korry, etc.) have holes that are the same size. And that means they will always snag on that large post and cause the flapper valve to fail to seat properly. If you have a Mansfield, the name is stamped in a fancy script in ink on the inside of the toilet tank, on the back. The model number is etched into underside of the toilet tank lid (usually a three digit number). So these flapper valves are the only ones I have found with one hole larger than the other, and they work great on Mansfield toilets that use flapper valves. And they are the only ones that do.
