Professional Applications & Engineering Value

These fluorosilicone rubber flat washers deliver critical performance where standard washers fail. The specialized fluorosilicone material combines the extreme temperature stability of silicone with enhanced fuel, oil, and solvent resistance of fluorocarbons, making them ideal for aerospace, automotive, and chemical processing applications. The precise 0.29" ID ensures perfect fitment on 5/16" screws, while the 0.688" OD provides optimal surface coverage. With operating capabilities from -60°F to 400°F, these washers solve common thermal expansion and compression set issues in high-temperature equipment, electrical enclosures, and engine compartments where thermal cycling would degrade ordinary rubber washers.
