Key Benefits: Made of flexible and elastic rubber plastic material, with fine workmanship, smooth surface, and no burrs, it has good elasticity, wear resistance, high-temperature resistance, high-pressure resistance, corrosion resistance, shockproof and not easily deformed. Black rubber flat washers show good sealing capabilities to various oil, water, and air, which can effectively prevent leakage. And can also be used for cushioning, reducing pressure and friction, increasing the contact area and providing a support surface for fasteners. Suitable Applications:The sealing, insulation and shock-absorbing properties of flat washers make them suitable for use in industries such as chemical industry, mechanical equipment, electronics, electrical appliances, construction, automobile engines, household pipe repairs, faucet pipes, etc. to ensure the safe operation of equipment and reduce the risk of leakage.Attention:Please confirm the washer diameter before ordering, and pay attention to regular inspection and maintenance of sealing gaskets
