Wiper ring GHF is composed of two elements particuarly indicated for rod application in double acting cylinders where conditions such as low friction are applied but yet able to perform the function of protecting from contamination of dust particles that eventually lead to the breakdown. The components include a reinforced PTFE ring and rubber spring element in NBR (for special applications a spring element in FKM should be applied) allowing the necessary sealing force in cases where high temperatures and high speed are present.
