Professional Applications & Engineering Value
This PTFE flat washer delivers critical engineering solutions where standard metal washers fail. The white PTFE plastic construction provides inherent chemical resistance against corrosive fluids and solvents, making it ideal for chemical processing, pharmaceutical, and food manufacturing equipment. The material's low friction coefficient prevents galling and seizing on No. 12 screws, while the 500°F maximum temperature rating ensures performance in high-heat applications like automotive, aerospace, and industrial oven assemblies. The precise 0.25" ID x 0.5" OD dimensions maintain secure fastening while the Durometer 55D hardness offers perfect balance between compression and durability for long-term reliability.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.25" inner diameter and 0.5" outer diameter, specifically engineered for No. 12 screw applications. The thickness tolerance of 0.057-0.067" ensures consistent performance across production batches. Manufactured from premium PTFE plastic with Durometer 55D hardness, the washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
