security seal techniques using materials

security seal is made of quality synthetic rubber O-ring and a rubber cloth Y-shaped ring composed of superimposed, relying on its own deformation of the sealing surfaces produce higher initial contact stress, no pressure to prevent leakage of fluid. Hydraulic working cylinder, Security seals the pressure oil so that the elastic deformation of the O-ring is always squeezed and stretched in the Y-ring sealing lip, so that close to the sealing surface, and together with the initial contact stress to prevent leakage of pressurized oil . security seal structure and format similar to circle, but also by a rubber O-ring with PTFE special quality rectangular or trapezoidal shape consisting of seals, Lancaster closure and can be divided into the same tamper evident seals cell to circle the hole with Sri Lanka Manchester special seal and shaft seal, seal and sealing mechanism Lancaster closure and cell to circle the same, but the security seal has only a one-way seal. Lancaster closure and cell to circle the common feature is filled PTFE material quality, low friction, no stick-slip, long life.
