Caterpillar 109-0078 Seal-O-Ring: Durable OEM-Grade Seal for Articulated Dump Trucks and Cold Planers
The Caterpillar 109-0078 Seal-O-Ring is a precision-engineered component designed to provide superior sealing performance in a wide range of heavy equipment applications. Manufactured to OEM specifications, this seal-o-ring ensures optimal fit and function in various Caterpillar articulated dump trucks and cold planers. Crafted from high-grade elastomeric materials, the seal offers excellent resistance to hydraulic fluids, extreme temperatures, and abrasive contaminants, making it ideal for demanding drivetrain and hydraulic system environments. Its robust design supports reliable sealing under high-pressure load conditions, minimizing leakage and enhancing overall equipment efficiency.
Technically, the 109-0078 Seal-O-Ring features a critical cross-sectional diameter tailored to maintain a tight seal within the hydraulic cylinders and joints of models such as the 2YR-D400E, 8TF-D400D, and 5ZS-PM-465 Cold Planer. The material metallurgy combines flexibility with tensile strength, ensuring long service life and reduced downtime. This seal’s compatibility with a broad range of Caterpillar machinery—from articulated dump trucks to cold planers—makes it an essential spare part for maintaining peak operational performance and extending equipment longevity.
