Piston Seal SPGW

SPGW heary duty piston seals are designed for double acting hydraulic cylinders used in heary 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 sevice.  Therefore, SPGW is very suitable for heary duty applications.
