Ideal Standard Close Coupling Ring Washer Doughnut Toilet WC Cistern

The doughnut supplied with the WC was practically useless. It gave the impression that all is well until you do an overflow test and sure enough the system leaked like a sieve. The replacement doughnut is a perfect fit and the rubber is soft enough to be tightly squashed between the cistern and the pan to ensure a perfect seal. Definitely recommend.

Good quality

Good Purchase

Quite thick - perfect replacement and after tightening up the fittings immediately, it immediately stopped the leak.

The size was not for ideal coupling required

If this is the right part for your pan and cistern, older Ideal and American Standard definitely use this, then the product will be perfect at forming a water-tight seal. The ring is 110mm outer diameter and 80mm internally. I expect this will last the 25+ years the last one did!!

Brought as a replacement cistern rubber seal,the size was OK and as ordered,but the seal was too hard and wouldn't pull down enough to form a water tight seal.Leaving a gap between the cistern and toilet pan.

I bought this as it looked like something that I had removed from my Roca toilet but it was not suitable so wasted my money.
