China Ceramic Mechanical Seals Ring or Face Supplier, Manufacturer - Factory Direct Price

Product Description

Ceramic Mechanical Seals Ring or Face is a sealing device made of ceramic material, mainly used to prevent fluid or gas leakage. Ceramic material has a wide range of applications in the field of mechanical seals due to its excellent wear resistance, corrosion resistance, high temperature resistance and high hardness.

High Quality Alumina Ceramic Rings

Alumina Ceramic is the widely used technical ceramic materials. It has high wear resistance, high mechanical strength, high temperature resistance, good thermal shock resistance, excellent electrical insulation. It is usually used for electrical insulators, wear resistant parts, ceramic parts for high temperature furnace etc. Alumina Ceramic can be made by different purities like 95%, 96%, 99%, 99.5%, 99.7% etc, their properties will have little difference accordingly. Leap industry provide different purity Ceramic what can be fit for the different requirement application area
