Professional Applications & Engineering Value

These fluorosilicone rubber flat washers deliver critical sealing solutions where standard elastomers fail. The fluorosilicone material combines silicone's temperature stability with enhanced chemical resistance, making these washers ideal for automotive, aerospace, and chemical processing applications. They effectively seal against fuels, oils, and solvents while maintaining flexibility from arctic cold to engine compartment heat. The 0.29" ID ensures precise fit on 5/16" screws, preventing misalignment and leakage points. With thickness tolerance of 0.052-0.072", these washers provide consistent compression for reliable sealing performance in demanding industrial environments where temperature extremes and chemical exposure compromise ordinary sealing components.
