Professional Applications & Engineering Value
This SBR rubber flat washer delivers critical engineering solutions where conventional washers fail. The Durometer 70A hardness provides optimal balance between flexibility and compression resistance, making it ideal for vibration damping in machinery, electrical enclosures, and automotive assemblies. The polyester fiber filler significantly enhances tear resistance while maintaining consistent performance across the 0.105-0.145" thickness range. These black rubber washers excel in sealing applications where they prevent fluid ingress and compensate for surface irregularities. With temperature resistance up to 170°F, they maintain integrity in engine compartments, HVAC systems, and industrial equipment exposed to moderate heat cycles and environmental stressors.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 1.188" inner diameter and 1.5" outer diameter for perfect fit with 1 1/8" screws. The SBR rubber material with polyester fiber reinforcement ensures consistent performance across the specified 0.105-0.145" thickness tolerance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates, guarantees these industrial washers meet global environmental and safety standards for professional applications.
