AI Overview
The 79mm (OD) x 54mm (ID) toilet cistern gasket is specifically designed as a replacement seal for Mansfield flush valves (models 210, 211, and others), often used to repair running toilets by creating a watertight seal. These are frequently made of red or black silicone/rubber for durability.
Key Product & Replacement Info:
- Dimensions: Approximately 3.1-inch (79mm) Outside Diameter (OD) x 2.2-inch (54mm) Inside Diameter (ID).
- Compatibility: Fits Mansfield 210/211 flush valve assemblies.
Installation Tips:
- Turn off the water supply and flush to empty the tank.
- Remove the existing seal from the flush valve (you may need to unscrew the plastic nut holding the flush valve in place to access it properly).
- Clean the area thoroughly to ensure the new seal sits flat.
- Apply the new 79mm x 54mm seal and reassemble.
