The thickness of gasket is related to its form, material, diameter, sealing surface condition and sealing medium.For most nonmetallic plates, a thin 1.5mm or 2mm thick gasket is usually used.This is because the thinner gasket, exposed to the internal pressure of the surface area is small, the medium leakage along the body is less, so the leakage rate is low, and the gasket extrusion force is small;Thinner spacers have lower creep relaxation;The thinner the gasket, the lower the price.
