_ •Low costs, •Savings from space. Requiring less volume than other sealing elements which work identical, •Sealing on both sides. •Requinng less experience on assembling, without dangerous slate on reverse asoembling, •Easy machining of 0-Ring grooves. •Being used more efficiently on low tolerated surfaces than other gaskets on static working. Operation Features Sealing efficiency of 0-Ring e based on the axial and radial deformation whole assembling Occurs This deformation can be found with optimized design of the housing The ensuing reaction force of rubber gives the contact pressure which is necessary for sealing, and this is additionally supported by the pressure of media. 0-Ring's material acts Re a type &fluid which viscosity is very high. If the radial space between thesealing surface and groove comers is Inn much and pressure at which 0-rings can work without extrusion failure is therefore controlled by the hardness of the 0-ring and the working gap. If there won't be any leaking clearance and 0-Ring MI be used in static conditions there is not an exact pressure rate to resist. It Is simple to scale the 0-Ring grooves. While scaling, it is needed to be careful about groove heights for defining ratio of compression. There are types of 0-Ring grooves like; dynamic (hydraulic and pneumatic), radial compressed (static), triangle and trapeze. The hardness of 0-Ring material changes between 60 to 90 Shore A. ViAlite soft materials (60 Shore A) are Suitable for ensuring a better sealing at low pressure (static Operations <160 bar, dynamic operations <63 bar), harder materials (90 Shore A) are suitable for sealing at high pressure (slats° operations >160 bar, dynamic operations >63 bar). Common used 0-Rings have 70 Shore A hardness. Pressure and operation clearance are the major factors at determining the hardness or 0- Ring. It is suitable to use a harder material when pressure and operation clearance increases.
