4 Pieces Toilet Flush Valve Seal Leak Proof Tank Fitting Easy to Install Replacement Set for Plumbers, Bathroom, Public Facility
These toilet flush valve seal washers are designed as replacement parts for tank flush mechanisms, helping restore reliable operation when the original gasket has worn out. Each washer is shaped to fit around the base of a compatible flush valve, providing a consistent sealing surface where the valve meets the tank outlet.
By forming a tight barrier between the flush valve and the tank opening, the seal helps reduce or stop water leakage from the toilet tank. A properly fitted seal can support stable water levels, contribute to efficient flushing performance and help avoid continuous refilling caused by slow leaks.
The seals are made from silicone, a flexible material that conforms well to mating surfaces. This flexibility supports good contact and helps the washer return to shape after repeated flush cycles, while the material’s resistance to general wear allows it to be used over an extended period under normal conditions.
Each washer has an outer diameter of about 6.7cm/2.64inch, an inner pore diameter of about 3.1cm/1.22inch and an approximate thickness of 0.3cm/0.12inch. These measurements are intended to match the original gasket used on compatible valves; comparing these dimensions with your existing part can help confirm suitability before replacement.
The set contains 4 identical silicone seals specifically sized for C7715-6 flush valve sets. Having multiple pieces on hand allows you to replace several worn gaskets at once or keep spares available for future maintenance of compatible toilets.
Installation is generally straightforward on a compatible C7715-6 flush valve. After turning off the water supply and draining the tank, the old seal can be removed from the base of the valve, the contact area wiped clean, and a new silicone washer pressed into position before reassembling the valve and restoring the water supply.
These seals can be used wherever toilets are equipped with C7715-6 flush valve sets, such as in household bathrooms or shared restrooms that use this model. Regularly checking the condition of the gasket and replacing it when it shows signs of aging can help maintain consistent flushing and reduce unwanted water usage.
