Hydraulic SPGW Piston Seal
SPGW heavy duty piston seals are designed for double acting hydraulic cylinders used in heavy duty applications. They consist of PTFE ring, 2 POM support ring and NBR pressure ring. Some advantages are its simple design, high linear velocity values, non-bonding property on the surface in long static cases, low friction, wider permissible gaps and long life service. Therefore, SPGW is very suitable for heavy duty applications.
