In the hydraulic system and its system, the seals used to prevent leakage of working medium and the outside world of dust and foreign invasion. Which sealed the role of components, ie seals. Leakage will result in waste of the working medium, pollution machines and the environment, and even lead to mechanical malfunctioning equipment, personal accident. Internal leakage volumetric efficiency of the hydraulic system will cause a sharpbsp hydraulic fittings decline, reaching less than the required working pressure can not even work. Invasive system of tiny dust particles, can cause or exacerbate the wear of hydraulic components, and further lead to leakage. Thus, seals and sealing devices is an important component of the hydraulic equipment. Reliability and service life of its work is an important indicator to measure the hydraulic system is good or bad. The gap metric hydraulic hose fittingsseals are the seals, so that two adjacent gap in the coupling between the surface control in the minimum clearance below the liquid through sealed. Contact seals divided i nto self-sealing compression seal and self-sealing self-tight seal (lip seal) two.hydraulic couplings
