NBR hydraulic oil seal YXD/ODU seal ring gasket Description-Hydraulic Oil Seal: Hydraulic seals are generally made from elastomers, natural and synthetic polymers, which possess weak molecular attraction and highly elastic properties. Two major sources for hydraulic seals are rubber and plastics (including PTFE and polyurethane). Other elastomer materials used to fabricate seals include butadiene, nitrile, butyl, and silicone. Seals made with these and other elastomeric materials are usually fabricated through extrusion, although hydraulic seals are sintered in an oven from a powder form. Seals may also be made from non-elastic materials such as felt and leather. Some particular types of hydraulic seals (e.g. bonded seals) are made from metallic materials (including brass, bronze, aluminum, carbon steel, and stainless steel). All of the metal materials used to create seals may be plated or galvanized for added oxidation protection and strength. The adhesion between the rubber material and metal of a bonded seal is created via chemical bonding. Hydraulic seals are divided into two main groupings: static and dynamic.
