Professional Applications & Engineering Value
These PVC plastic flat washers deliver critical engineering solutions where chemical resistance and electrical insulation are paramount. The gray PVC material provides exceptional protection against corrosive substances commonly found in chemical processing, water treatment, and industrial manufacturing environments. The precise 0.188" ID ensures perfect fitment with No. 8 screws, eliminating play and maintaining fastener integrity. As electrical insulation washers, they prevent galvanic corrosion and current leakage in electrical enclosures, control panels, and electronic assemblies. The Durometer 65D hardness offers optimal balance between flexibility and load-bearing capacity, making them ideal for applications requiring vibration dampening while maintaining dimensional stability under compression loads.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.188" inner diameter, 1" outer diameter, and controlled thickness range of 0.025-0.035". Manufactured from PVC plastic with Durometer 65D hardness and maximum temperature rating of 140°F. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. Designed specifically for use with No. 8 screw sizes in industrial fastening applications requiring chemical resistance and electrical insulation properties.
