Professional Applications & Engineering Value

This fluorosilicone rubber flat washer delivers critical performance where conventional elastomers fail. The specialized fluorosilicone material maintains elasticity and sealing integrity across extreme thermal cycling from -60°F to 400°F, preventing leaks in automotive, aerospace, and industrial processing equipment. Its Durometer 60A hardness provides the ideal balance between conformability and structural support, creating reliable seals against fluids, fuels, and chemicals while resisting compression set. The precise 5/8" screw size compatibility and controlled thickness ensure consistent clamping force in demanding applications where temperature fluctuations would degrade standard rubber washers.

Specification Summary & Compliance
