Core Features
Static sealing and leak prevention: Pre-compression within the groove forms an elastic sealing surface, preventing oil leakage between static mating surfaces and maintaining stable system pressure.
Dust and contamination prevention: Prevents construction dust, mud, and impurities from entering the sealing cavity, protecting internal components and preventing wear and oil contamination.
Buffering and compensation: The elastic material absorbs gap fluctuations caused by vibration and temperature changes, continuously maintaining sealing performance and adapting to the high-frequency vibration conditions of bulldozers.
Universal compatibility: Adaptable to static sealing needs in multiple locations, simplifying inventory and procurement management.
Product Superiority
Original Factory Precise Fit: Dimensions (inner diameter, wire diameter, tolerances) perfectly match the machine's sealing grooves, allowing for direct replacement without adjustment and eliminating leaks caused by dimensional deviations.
Strong Material Compatibility: The nitrile rubber (NBR) base material is resistant to mineral oil/hydraulic oil and has a temperature range of -30℃ to +100℃, adapting to system oil temperatures and media environments.
Reliable Structure: Circular cross-section bidirectional seal, pre-compressed for a tight fit, static sealing pressure up to 35 MPa, adapting to hydraulic system pressure requirements.
Cost and Maintenance Friendly: Low unit price, easy installation, and a normal operating service life of ≥2000 hours, reducing downtime for replacements.
High Versatility: Compliant with AS568 standards, compatible with high-quality aftermarket parts, offering flexible procurement options.
Installation and Maintenance Points
Before installation, clean the grooves and mating surfaces to remove burrs, oil, and impurities to avoid scratching the seal surface.
During installation, avoid twisting or stretching. Apply clean hydraulic oil to the seal and groove to aid installation and reduce friction.
Control the pre-compression amount between 15% and 30%. Excessive pre-compression can lead to permanent deformation, while insufficient pre-compression will affect the sealing effect.
Check for leakage at the sealing points every 1000 hours and replace the seal every 2000 hours to prevent aging and failure.
Fit scenarios and value
Suitable for: Static sealing points such as hydraulic pump valve interfaces, cylinder end caps, pipeline flanges, and gearbox/hydraulic oil tank seals, especially suitable for dusty, heavy-duty mining/construction environments.
Core Value: Reduces oil leakage by approximately 95%, reduces oil loss and component wear due to seal failure, extends system life by approximately 15%–20%, and lowers overall maintenance costs.
