Gasket→Cork Rubber Sheet Gasket
Cork Rubber Sheet Gasket ZW#2950
It is a highly compressible material suitable for low and medium bolt pressure, with good flexibility and resilience. The physical characteristics along with oil and fuel resistance make ZW 2950 a qualified material for automotive and industrial gaskets. This also creates a better distribution of load when compression occurs between bolt spans. Thanks to the combination between the compressibility and recovery characteristics of cork with the flexibility and shelf life of synthetic rubber, ZW 2950 CorkRubber Sheet Gasket proves it as an excellent product for sealing, insulation or anti-vibration applications. These unique characteristics will meet or exceed gasketing requirements in automotive, aerospace, marine, gas, electrical and many other industries.
