Hydraulic SPGW Piston Seal

Product Description

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.
