Professional Applications & Engineering Value

This EPDM rubber flat washer delivers critical engineering solutions where standard metal washers fall short. The ethylene propylene diene monomer rubber composition provides exceptional resistance to oxidation, ozone, and weathering, making it ideal for outdoor equipment, automotive components, and industrial machinery exposed to harsh elements. The 0.12" ID x 0.25" OD dimensions ensure precise fitting with No. 6 screws, while the flat washer design distributes clamping force evenly to prevent surface damage. With its temperature resistance from -20°F to 212°F, this washer maintains flexibility and sealing integrity in both freezing conditions and steam applications, solving common failure points in plumbing, HVAC, electrical enclosures, and automotive assemblies where thermal cycling occurs.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.12" inner diameter, 0.25" outer diameter, and thickness ranging from 0.047" to 0.077". Manufactured from black EPDM rubber with Durometer 55A hardness for optimal compression and recovery. The product is fully RoHS 3 (2015/863/EU) compliant, meeting stringent environmental regulations for hazardous substance restrictions. Suitable for use with No. 6 screw sizes and engineered to withstand continuous service across the specified temperature range without degradation of sealing properties or material integrity.
