Professional Applications & Engineering Value
Engineered for demanding industrial environments, these SBR rubber flat washers deliver critical vibration damping and sealing performance in machinery, automotive, and HVAC systems. The polyester fiber reinforcement provides exceptional tear resistance while maintaining flexibility, solving common failure points in high-stress applications. With chemical-resistant SBR material and Durometer 70A hardness, these washers maintain compression set resistance under continuous load, ensuring long-term sealing integrity in piping systems, electrical enclosures, and industrial equipment where temperature fluctuations and mechanical stress are constant challenges.
Specification Summary & Compliance
Manufactured to inch system standards with precise dimensions: 0.656" ID, 1.312" OD, and thickness range of 0.078-0.108" for 5/8" screw size applications. These flat washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring material safety and environmental responsibility. The Durometer 70A hardness provides consistent performance across the specified maximum temperature of 170°F, with polyester fiber filler enhancing dimensional stability for reliable service in industrial fastening systems.
