- Enhanced durability through polyester fiber reinforcement maintains structural integrity under compression and repeated use
- Optimal hardness balance with Durometer 70A rating provides both flexibility for sealing and firmness for load distribution
- Reliable temperature resistance up to 170°F ensures consistent performance in various operating conditions
- Precise dimensional fit with 1" ID and 3" OD accommodates standard inch-system fasteners for easy installation
- Environmental compliance with RoHS 3 (2015/863/EU) meets strict industrial regulatory requirements
Professional Applications & Engineering Value
These SBR rubber flat washers deliver critical engineering solutions where vibration damping and fluid sealing are paramount. The Durometer 70A hardness provides the ideal balance between compression set resistance and sealing capability, while the polyester fiber reinforcement prevents deformation under sustained bolt loads. Engineered for industrial applications including machinery mounting, plumbing systems, and automotive assemblies, these black rubber washers effectively isolate vibration, reduce noise transmission, and create reliable seals against moisture and contaminants. The inch-system dimensions ensure compatibility with standard 1" fasteners, making them essential components for maintenance and manufacturing operations requiring consistent performance.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 1" inner diameter, 3" outer diameter, and 0.110-0.140" thickness tolerance. Constructed from SBR rubber with polyester fiber filler reinforcement and Durometer 70A hardness rating. Compliant with RoHS 3 (2015/863/EU) environmental directives and rated for continuous service up to 170°F maximum temperature. Designed for use with 1" screw sizes in inch-system applications.
