Professional Applications & Engineering Value
This SBR rubber flat washer delivers critical engineering solutions for industrial applications where vibration resistance and reliable sealing are paramount. The Durometer 70A hardness provides optimal flexibility while maintaining structural integrity, effectively absorbing mechanical shocks in heavy machinery, automotive assemblies, and industrial equipment. The polyester fiber filler reinforcement prevents washer collapse under sustained pressure, making it ideal for bolted connections requiring consistent sealing performance. With its 0.75" ID precisely matching 3/4" screw sizes and generous 3" OD contact surface, this washer creates effective barriers against moisture, dust, and air infiltration in mechanical systems operating at temperatures up to 170°F.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.75" inner diameter, 3" outer diameter, and controlled thickness ranging 0.110-0.140" for precise fitment. Manufactured from SBR rubber with Durometer 70A hardness and reinforced with polyester fiber filler for enhanced durability. The product is fully RoHS 3 (2015/863/EU) compliant and designed to withstand maximum operating temperatures of 170°F while maintaining performance characteristics.
