High-Temperature O-Ring for Hydraulic Rock Drills Engineered for extreme mining environments, this O-ring ensures reliable sealing in hydraulic rock drills and other heavy-duty equipment. Constructed from FKM fluoroelastomer with 70 Shore A hardness, it withstands high temperatures, aggressive fluids, and mechanical stress, making it ideal for prolonged use in underground mining and quarrying operations.
Technical Specifications & Design The O-ring adheres to ISO 3601-1 standards, featuring a 40 mm inner diameter with a 5.3 mm cord thickness (Class B dimensions). Its precision-machined cross-section ensures a 15-20% compression ratio in 5.7 mm wide mounting grooves, providing leak-free performance under dynamic and static conditions. The chamfered edges facilitate easy installation without damage to the sealing surface.
