Professional Applications & Engineering Value

These clear polyurethane rubber flat washers deliver critical engineering solutions where standard metal washers fall short. The Durometer 70A hardness provides ideal compression characteristics for effective vibration damping in machinery, automotive, and electronic assemblies, significantly reducing maintenance frequency. The temperature resistance from -10°F to 150°F ensures reliable performance in both cold storage and moderate heat environments. As sealing washers, they create effective barriers against moisture and contaminants while maintaining visibility for quality control. The precise 0.53" ID and 1" OD dimensions guarantee proper fitment for 1/2" screw applications, preventing installation errors and ensuring consistent pressure distribution across fastened surfaces.

Specification Summary & Compliance

Manufactured to exact inch system specifications with 0.53" inner diameter, 1" outer diameter, and 0.085-0.101" thickness range. These flat washers meet industrial standards for dimensional accuracy and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in global markets. The polyurethane rubber material maintains consistent performance across the specified temperature range while providing the durability needed for repeated compression cycles in industrial fastening applications.
