HBY Hydraulic Seals – Rod compact seals

Description

HBY Piston Rod Seal, known as the buffer seal ring, consists of a soft beige polyurethane seal and a hard black PA anti-extrusion ring added to the heel of the seal. In addition, Hydraulic Oil Seals are an integral component of most hydraulic systems and are generally made from elastomers, natural and synthetic polymers. Hydraulic oil seal provides exceptional water and air sealing capabilities, hydraulic seals are ring-shaped and primarily designed to eliminate or limit the leakage of fluid moving within a hydraulic or pneumatic system.HBY Piston Seal is used in conjunction with piston rod seals to absorb shock and fluctuating pressures under high loads, to isolate high-temperature liquids, and to improve seal durability.Hydraulic Rod Buffer Seal Ring HBY is used together with rod seal.In this way it can improve seal durability because after absorbing shock and wave in high load capacity it can be isolated from high temperature fluid.
