Seal gasket for cistern/bowl CERSANIT COAR1000450957 – foam gasket for compact toilet

Foam gasket for cistern and bowl connection designed for compact toilets by CERSANIT. This porous foam seal provides a compressible, resilient barrier between the cistern outlet and the toilet bowl inlet to prevent leaks and to dampen vibration at the joint. The gasket is intended for use when repairing or replacing the original cistern-to-bowl seal on compatible compact toilet models and is suitable for routine maintenance and installation tasks.

Advantages

The foam construction offers good compression and recovery to maintain a tight seal under varying pressure and temperature conditions. Its porous structure absorbs minor misalignments and surface irregularities, reducing the risk of water seepage. The gasket is lightweight and easy to handle during installation, and it contributes to quieter operation by reducing vibration transfer between the cistern and bowl.

Suitable for

• Repairing a leaking connection between cistern and compact toilet bowl
• Replacing an aged or deformed cistern-to-bowl seal
• Routine maintenance during toilet servicing or renovation
• Reducing vibration and noise at the cistern-bowl joint

Key specifications

• Material: porous compressible foam
• Function: cistern-to-bowl sealing and vibration damping
• Form: ring-shaped gasket sized for compact toilet connections
• Operating conditions: suitable for contact with potable water and typical bathroom temperatures
• Installation: designed for press-fit or seated placement between cistern outlet and bowl inlet

How to use

Before installation, turn off the water supply and empty the cistern. Remove the cistern from the bowl if required by your toilet model and clean mating surfaces to remove residue and old seal material. Position the foam gasket around the cistern outlet or into the bowl inlet as specified by the toilet manufacturer so that it sits evenly and without folds. Reattach the cistern, tighten mounting hardware to the manufacturer's recommended torque, restore the water supply and check for leaks. If small leaks remain, re-seat the gasket and ensure even compression.

Usage recommendations

Use the foam gasket as a direct replacement for the original cistern-to-bowl seal on compatible compact toilets. Avoid using petroleum-based cleaners or solvents on the gasket material, and inspect the seal periodically for signs of compression set or degradation. Replace the gasket if it becomes brittle, torn, or fails to maintain a watertight connection.
