Professional Applications & Engineering Value

Engineered for demanding industrial environments, these fluorosilicone rubber flat washers deliver critical sealing solutions where temperature extremes and chemical exposure compromise ordinary materials. The fluorosilicone rubber construction maintains elasticity and sealing integrity across a remarkable -60°F to 400°F range, preventing leaks in automotive, aerospace, and chemical processing equipment. With Durometer 60A hardness, they provide ideal compression recovery for 5/16" screw applications while resisting ozone, fuels, and oils. The precise 0.29" ID and 0.562" OD dimensions ensure perfect alignment with standard fasteners, eliminating installation errors in high-vibration machinery. These industrial washers solve common failure points in thermal cycling systems where inferior materials become brittle or degrade.
