Professional Applications & Engineering Value

These SBR rubber flat washers deliver critical engineering solutions where vibration isolation and environmental sealing are paramount. The Durometer 70A hardness combined with polyester fiber filler creates a robust matrix that withstands compression set and maintains sealing integrity under dynamic loads. Ideal for industrial equipment, automotive assemblies, and machinery requiring reliable gasketing, these inch-system washers prevent loosening from thermal cycling and mechanical stress. The black SBR material offers consistent performance across applications demanding temperature resistance up to 170°F while providing essential electrical insulation properties.
