This Rubber Seal Ring is a critical sealing component engineered for the hydraulic systems of excavators, loaders, and other heavy construction machinery. Manufactured from high-performance NBR (Nitrile) or FKM (Viton) rubber compounds, it is designed to effectively block fluid leakage and maintain stable hydraulic system pressure in extreme operating conditions, making it a key spare part for ensuring efficient equipment operation.
Premium Materials – Choose Your Performance:
We offer two high-performance rubber compounds to match specific operational demands:
NBR (Nitrile Butadiene Rubber): The industry-standard material offering excellent resistance to mineral oil-based hydraulic fluids and lubricants. It provides high cost-effectiveness for most conventional working environments.
FKM (Fluoroelastomer/Viton): Designed for extreme conditions. It delivers superior stability in high-temperature settings, against corrosive chemicals, or when exposed to synthetic hydraulic fluids, significantly extending service life.
Exceptional Oil & Wear Resistance:
Optimized for the high-pressure and high-speed dynamics of construction machinery hydraulics, the rubber compound features a special formulation. It possesses strong anti-swelling properties (resisting deformation upon oil contact) and outstanding wear resistance to withstand the friction of reciprocating piston rods, effectively preventing premature seal failure.
Precision Molding for a Perfect Fit:
Produced via precision compression or injection molding using high-accuracy molds, these rings feature uniform cross-sections and exact dimensions. The smooth surface finish ensures seamless integration into various sealing grooves (such as O-ring channels or Glyd ring housings), maintaining a tight seal even under high-pressure vibration.
Broad Equipment Compatibility:
Designed to meet international standards, this product integrates seamlessly with hydraulic systems found in excavators, loaders, bulldozers, and mining equipment from major brands. It is the ideal choice for maintenance and repair of hydraulic cylinders, pumps, control valves, and hose connections.
Customization Available:
We understand that standard parts do not cover every requirement. Therefore, we offer custom specification and model services. Whether you require a special rubber compound, non-standard inner/outer diameters, or a custom profile design, we can produce it according to your drawings or samples to solve your unique sealing challenges.

We strictly adhere to the ISO 9001 quality management system throughout production. Every batch undergoes rigorous dimensional checks and physical property testing to ensure the products are free from flash, bubbles, and impurities. We are committed to providing stable, durable sealing solutions that support the continuous and stable operation of your equipment.
Installation Recommendation:
Ensure the sealing groove is clean and free of burrs before installation. Apply a suitable amount of grease to the seal ring to prevent shear damage during assembly. For high-pressure static seals, always verify the correct installation of backup rings to prevent the seal from extruding into gaps.
