Great fit for 2” flush valve
Perfect fit for 2” cistern outlets. Added a fat worm of Plumbers Mait and no leaks.

Does the job perfectly
I'd had problems for some time with my Twfords close coupling toilet. I'd already purchased a new flush valve which helped in part but I was still having issues with a leak as none of the donuts I'd previously bought, whether rubber or foam did the job. They were all too bulky. This is perfect. No more leak, no gaps between the cistern and the bowl. I was going to purchase another for the downstairs toilet which was also leaking. However, it transpires fixing the upstairs toilet sorted the downstairs toilet (as the piping is connected) No leaks upstairs and no dripping downstairs. Win win. I honestly didn't think this would work but I gave it a go because of the price. I'm so glad I did.

No instructions for DIY
Well I used this and another item together, as the water would still splash out. Not the issue with the item in particular, it is just my cistern may need double seal.

Waste of money
Nowhere near as good as a standard "donut" deal and twice the price. Truly a waste of money.

Fits perfectly
Tried several washers to try to get a seal. Only this one fitted perfectly. Buy once and buy right.

Fits very well on Ibergrif M20522
Great product, fits very well syphon Ibergrif M20522. It has few steps so can fit from smaller to bigger. Also very thin and hard. Makes no leaks and neat look. Recommended!
