1. Graphite seal rings are mainly used for mechanical seals in various pumps and reaction. There is sliding end face seal in seal rings, and they are named rotary seal ring and stationary seal ring according different usage situation and effect. 

2. We choose hard carbon materials and graphite material with good self-lubrication for this product. We take full advantage of its good wear resistance, high temperature resistance, corrosion resistance, small coefficient of expansion and low friction coefficient. It is ideal material for various mechanical seal equipment.
