A properly selected sealing washer helps fill small gaps and irregularities between surfaces, improving sealing performance around bolts, screws and other fasteners. Grade One Fasteners supplies sealing washers in different materials, sizes, configurations and specifications according to customer and project requirements. What Are Sealing Washers? Sealing washers are specialized washers designed to create a seal around a fastening point. They are commonly installed beneath the head of a bolt or screw, or beneath a nut, depending on the assembly design. The primary purpose of a sealing washer is to help prevent leakage through or around the fastening hole. Depending on the design, a sealing washer may use rubber, elastomeric material, metal, bonded material or a combination of materials to achieve the required sealing performance. Sealing washers are widely used in applications where fastening and sealing are both required from the same assembly. How Do Sealing Washers Work? A sealing washer works by creating controlled contact pressure between the washer and the mating surfaces when the fastener is tightened. As the bolt, screw or nut is tightened, the sealing element compresses and conforms to small surface irregularities. This helps close potential paths through which liquids or gases could escape. The performance of a sealing washer depends on several factors, including: Selecting the correct washer is therefore important. A washer that physically fits the bolt is not automatically suitable for the application’s pressure, temperature or chemical conditions. Importance of Sealing Washers in Industrial Applications Leakage can create operational, safety and maintenance problems in industrial equipment. Even a small leak can lead to fluid loss, contamination, corrosion or equipment downtime. Sealing washers help provide additional protection at fastening points where a standard metal washer alone may not provide adequate sealing.
