PRODUCTS DETAILS

UNP/UHP Rod Seal is a kind of lip seal which is used in the groove to fit the piston.The materials are imported CPU and TPU, with a hardness of 90-95Ashore and green color. UNP/UHP Rod Seal is used in hydraulic cylinders for fluid sealing and is designed to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore. Besides, The choice of piston seal is decided by the way in which the cylinder operates. For a cylinder which is exclusively single-acting, capable of sealing dynamic pressure from one side (unidirectional), it is always best to choose the type of seal designed to provide optimum sealing qualities for single-acting functions.
