The seal is an agent that prevents leakage of oil from the hydraulic elements and protects the system from dust/dirt. A hydraulic seal is usually used to arrest both internal and external leakage of oil/gas/steam. It maintains pressure, prevent loss of fluid from the system and keeps out contamination in the system to enhance its service life and functional utility. In any kind of pressure actuated system, seal is necessary for rotary or reciprocating, static or dynamic system, steam, hydraulic or pneumatic medium. Seals may be categorized as per methods of sealing, areas of application, seal material, geometrical shapes of the seal used in the system etc. Hydraulic seal manufacturers create many products that are application specific and specially designed to prevent leaks under very particular circumstances.
