Core seal: This is the most fundamental function. Even if you lock the faucet tightly with a nut from below, there may be burrs or unevenness that are invisible to the naked eye at the edge of the installation hole on the sink or countertop. Water (especially the foam water used for washing up) will seep in slowly along these crevices. The material of the gasket (such as rubber or silicone) is elastic and can fill these gaps to form a waterproof barrier.
Protecting the countertop: Especially for expensive ceramic sinks, quartz or marble countertops, the hard metal faucet base is directly pressed, and long-term use may cause the countertop to crack or develop indentations. The soft gasket plays a role in buffering and distributing pressure.
Reduce vibration and noise: The ⅜×½ Bath Shoe Gasket can absorb the slight vibration generated when the faucet is in use, prevent the faucet from colliding with the countertop and making noise, and also make the hand feel more stable.
Compensating for unevenness: If the installation plane is not absolutely level, the elasticity of the gasket can compensate to a certain extent to ensure that the faucet does not shake after installation.
