Design 

  • PK8S has a self relieving seal design which prevents pressure from trapping and a simple groove design for easy installation. The self relieving design prevents excessive pressure build up in the cavity between buffer seal and rod seal. It has a special PTFE ring that has low frictional properties which are normally associated with this material but is strengthened by additives to reduce creep. PK8S comes in a wide range of materials for special applications.
