Metric Buffer Rod Seal

 

 

The Buffer rings have an NBR o-ring on the outside and Urethane ring on the inside for pressure spike applications. High quality urethane insures that the seal will stay energized at all pressures while the anti-extrusion ring helps protect the rod seal from rapid changes.
