Details

This Large Foam Doughnut Washer provides a reliable and flexible seal for modern close-coupled toilets. Specifically, we have designed this 2-inch siphon seal using a high-density foam that compresses more easily than rigid rubber alternatives. With an internal diameter of 70mm and an external diameter of 105mm, it is sized specifically for the larger flush valves found in many contemporary suites. For example, when you tighten the cistern bolts, the 10mm thick foam expands to fill the specific contours of the pan and cistern joint. Consequently, you can achieve a secure, leak-proof connection even if the ceramic surfaces are slightly irregular.

A leaking joint between the cistern and the pan is often the result of using a washer that is too small for modern, high-flow 2″ flush outlets. Furthermore, because these larger valves require a wider surface area to seal correctly, a standard 1.5″ washer will simply fail to bridge the gap. As a result, homeowners often experience significant leaks immediately after a flush, leading to damp floorboards and potential ceiling damage below. However, this 70mm x 105mm Large Foam Donut Washer solves these sizing and sealing issues effectively. Because it is precision-cut to fit 2-inch outlets, it provides the exact coverage needed for a watertight finish. Consequently, this creates a dry, stable union that prevents water damage without the need for excessive force during installation.
