KY-D Piston Seal, the shaft seal ring is widely used in a various copper cylinder and generally used in equipment oil cylinder to play a good sealing role in the reciprocating movement. And simple structure, easy to install, small cross-sectional area, products with oil resistance, wear-resistant properties of product use: for the reciprocating movement of the piston seal cylinder.
