6R5257 6R-5257 NYLON NBR Black Ring Seal Hydraulic Cylinder Loader Seal Kit

The 6R5257 hydraulic seal kit, also identified by the part number 6R-5257, is a high-performance sealing solution engineered specifically for excavator and loader hydraulic cylinders. This comprehensive kit features Nylon-NBR composite black ring seals, combining the structural strength of nylon with the exceptional oil resistance and wear durability of NBR (nitrile rubber) . Designed to meet the rigorous demands of heavy-duty construction equipment, 6R5257 ensures reliable sealing performance even under extreme pressure, temperature fluctuations, and harsh working environments such as construction sites and mining operations .​
Each 6R-5257 seal kit includes all essential components for complete hydraulic cylinder maintenance, including piston seals, rod seals, guide rings, and backup rings—eliminating the need for separate part purchases . The Nylon-NBR black ring seals within the 6R5257 kit exhibit superior compression set resistance and excellent compatibility with standard mineral oil-based hydraulic fluids, preventing leaks and safeguarding hydraulic systems from contaminants like dirt and debris . This compatibility makes 6R-5257 an ideal choice for popular excavator models such as 416, 416B, 446, M312, M313C, and M315, as well as various loader hydraulic cylinder assemblies .​
Manufactured in compliance with DIN 3760 and ISO 9001/TS 16949 standards , the 6R5257 hydraulic seal kit guarantees precise dimensional accuracy and consistent quality. The Nylon backing provides structural rigidity to resist extrusion under high pressure, while the NBR sealing lips deliver optimal flexibility for dynamic sealing applications in reciprocating hydraulic cylinders . Whether 用于 routine maintenance or emergency repairs, 6R-5257 simplifies installation, reduces downtime, and extends the service life of excavator and loader hydraulic systems .
