Durable material option hydraulic oil seals are designed for heavy duty excavator use in applications where sealing life and media compatibility are critical. Different materials can be selected based on temperature range, oil type, pressure conditions, and motion speed. NBR offers good oil resistance, PU delivers excellent abrasion resistance, FKM supports higher temperatures, and PTFE provides low friction performance. These custom size seals are widely used in cylinders and hydraulic assemblies for excavators, construction equipment, and maintenance service operations.
