Professional Applications & Engineering Value

Our SBR rubber flat washers deliver exceptional engineering value in demanding industrial environments where sealing performance and vibration isolation are critical. The black SBR rubber construction combined with polyester fiber reinforcement creates a robust sealing solution that maintains its form under compression, preventing fluid and gas leaks in piping systems, machinery enclosures, and equipment assemblies. These flat washers effectively solve common industrial challenges including bolt loosening from vibration, surface corrosion between dissimilar metals, and gasket failure in moderate temperature applications up to 170°F. The Durometer 70A hardness provides the ideal balance between flexibility for sealing and rigidity for load distribution, making them suitable for automotive, manufacturing, and plumbing applications where reliable industrial washers are essential for operational safety and maintenance efficiency.
