HNBR or PTFE made Hydraulic Seals are reckoned for their oil proof surface, compatibility with low and high temperature conditions. These seals can easily integrate with aliphatic hydrocarbons, ethylene glycol and petroleum based products. These have excellent thermal properties and their modulus of elasticity deserves praise. These are ideal for static and dynamic sealing procedures. Hydraulic Seals are acknowledged for their low movement friction rate, creeping free design, precise diameter and simple installation method. Quality of these sealing components has been tested on the basis of their temperature range, tensile strength, resilience level, compression deformation rate, modulus level and hardness range.
