Delta Seal Design: The gland assembly utilizes Caterpillar's innovative Delta seal technology. This seal design is geometrically optimized to create an efficient seal with significantly lower friction than conventional seals. Reduced friction is crucial for smooth, precise control and improved hydraulic efficiency.
Multi-Stage Contamination Defense: The system includes a heavy-duty, positive-action wiper seal to aggressively remove mud and abrasive contaminants. Behind it, a combination of specialized buffer seals and pressure-containing seals ensures high-pressure fluid stays in and contaminants are kept out, dramatically extending component life.
