Designed as a replacement sealing ring for underwall/behind-wall toilet cistern systems, it provides a flexible, water-tight seal between the flush valve components.

## Long description

CERSANIT silicone flush valve gasket K99-0167 is a replacement sealing ring designed for concealed cisterns and in-wall toilet systems. Made from flexible silicone, the gasket forms a watertight seal between flush valve components to prevent leaks and maintain reliable flushing performance in compatible CERSANIT, HI-TEC and LINK installations. The part is intended for repair and routine maintenance of underwall cisterns where a worn or damaged seal affects operation.
Advantages
The silicone construction offers elasticity and resistance to compression set, helping the gasket retain sealing performance over repeated flushing cycles. Its shape and dimensions match the mating surfaces of compatible concealed flush valves, ensuring a snug fit that minimizes water loss and reduces the risk of noise or partial flush problems caused by poor sealing. The material is durable in typical domestic water conditions and resists softening or cracking that can occur with age.
Suitable for
Repairing leaks in concealed cisterns and in-wall toilet frames.
Replacing worn flush valve seals during scheduled maintenance.
Servicing CERSANIT, HI-TEC and LINK compatible underwall cistern systems.
DIY bathroom plumbing repairs where the flush valve seal is the suspected fault.
Key specifications
Material: silicone elastomer suitable for potable water contact.
Function: sealing ring for flush valve to ensure watertight connection.
Compatibility: designed for concealed cistern flush valve geometries of matching models.
Durability: resistant to compression set and compatible with typical bathroom water temperatures and chemicals.
Form: flexible ring shaped to fit flush valve mating surfaces.
How to use
Shut off the water supply and flush the cistern to drain remaining water before starting. Access the flush valve by removing the cistern cover or servicing panel according to the installation instructions for the frame or cistern. Carefully remove the old gasket from the flush valve seat, clean the mating surfaces of debris and mineral deposits, and inspect for damage. Fit the silicone gasket into the valve seat ensuring it sits evenly without twists or folds. Reassemble the valve components, restore the water supply and test for leaks by performing several test flushes. If any leakage or improper sealing is observed, recheck the seating and repeat the installation steps.
Usage recommendations
Use appropriate tools to avoid damaging the valve seat or surrounding plastic parts. Replace the gasket if you observe visible deformation, cracks, or persistent leaks after installation. For best results, clean mineral buildup from mating surfaces before installing the new seal and confirm compatibility with the specific concealed cistern model prior to purchase.
