A sealing washer is a precision fastener component that creates a fluid-tight seal between a fitting, bolt, or plug and the mating surface it threads into. By deforming slightly under torque, it fills microscopic surface irregularities and prevents oil, hydraulic fluid, or coolant from escaping around the fastener. When a sealing washer becomes crushed, cracked, or corroded, the joint it protects will begin to weep or leak, which can accelerate wear on surrounding components and lead to more significant repairs if left unaddressed.
