Hydraulic piston seals, or piston rings, are essential components in hydraulic cylinders, designed to prevent fluid leakage and maintain pressure within the system. Positioned inside the cylinder head, these seals create a tight barrier against the cylinder bore, ensuring that hydraulic fluid remains confined to one side of the piston. This pressure differential is crucial for the efficient extension and retraction of the cylinder. HydraPak Seals offers a wide array of piston seal designs, including lip seals, PTFE capped expanders, and custom-engineered solutions crafted from high-performance elastomers and engineered plastics. These seals are vital for applications ranging from air compressors to hydraulic pumps. They provide maximum durability, sealing performance, and maintaining system efficiency by preventing fluid bypass and ensuring reliable piston movement under varying pressures.
