Experiencing severe fluid bypass inside your main pressure cylinders or noticing a persistent drop in hydraulic cycle speeds as the oil reaches its peak operating temperature? Worn-out elastic sealing rings fail to contain high-pressure hydraulic oil within the piston chambers, letting volume flow escape into the low-pressure suction side and forcing your engine to work harder to move less material. Overhaul your pressure boundaries and reclaim original system efficiency by installing the high-resiliency RITO 311506 piston ring today.
