  • PU82 MERKEL PROFILED RING

    This is a symmetric compact sealing ring made from TPU and is particularly used for static sealing of cylinder heads with end position damping. Cover seals PU 82 is distorted through forming and essentially less by the operating pressure and bridge issues through high tensile strength of the material gaps which develop from the elastic stretching of cylinder barrels. PU 82 has proved itself mostly in engineering machinery cylinders with pressure peaks of up to 600 bar in end position damping.
