Stop leaks quickly - with high-quality silicone construction
Medical-grade silicone offers elasticity and compressive resilience so seals conform to valve seats and resist permanent deformation. The material maintains a tight interface under typical cistern pressure, preserving the seal over repeated cycles.
Reliable sealing reduces persistent drips and prevents wastage of water, restoring normal flush performance and reducing the need for repeat repairs.
Fit most cisterns easily - with universal dimensions
Bottom outer diameter measures 1.06 inches (27mm), inner diameter 0.90 inches (23mm), and height 0.59 inches (15mm). Compatibility covers most side-entry and bottom-entry valve designs thanks to those standard measurements.
One set covers a wide range of toilet models, so fewer returns and less time spent checking exact valve types before purchase.
Repair in minutes - with straightforward replacement steps and spare seals
Replacement requires isolating the water supply, flushing the cistern, removing the old seal and aligning the new seal's vertical plastic line with the cover groove, then tightening and resetting the float horizontally. A pack of three provides spares for additional repairs.
Quick, repeatable repairs let households fix leaks without calling out a plumber, and spare seals keep future fixes simple and immediate.
