Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions in industries where high-temperature stability and chemical resistance are paramount. Designed for No. 3 screw size applications, its white PTFE construction effectively seals and protects assemblies in chemical processing, aerospace, and automotive systems exposed to extreme heat up to 500°F. The flat washer design evenly distributes clamping force, preventing galvanic corrosion and leakage in corrosive environments. By utilizing inch system measurements like 0.116" ID and 0.25" OD, it ensures precise fitment, reducing installation errors and maintenance downtime. Its inherent low friction coefficient minimizes thread galling, making it ideal for repeated disassembly in equipment servicing, while the Durometer 55D hardness maintains seal integrity under vibration, offering long-term reliability in demanding industrial settings.
