Caterpillar 077-3548 Seal-O-Ring: OEM-Grade Durability for Excavators and Cold Planers
The Caterpillar 077-3548 Seal-O-Ring is a precision-engineered sealing component designed to meet the rigorous demands of heavy-duty Caterpillar machinery, including a wide range of excavators (models 3XK-320, 9WG-320-A, 8ML-322, 7WL-322-A, 2SK-325, and more) and cold planers (5XC-PR-1000C, 7DC-PR-450, 8AC-PR-750B). Manufactured from high-grade elastomeric materials, this O-ring provides exceptional resistance to hydraulic fluids, extreme temperatures, and abrasive contaminants. Its exact dimensions ensure a perfect fit within the drivetrain and hydraulic systems, maintaining optimal pressure and preventing fluid leaks under high load conditions.
Technically, the 077-3548 Seal-O-Ring features superior elasticity and compression set resistance, which enhances its lifespan even in harsh operating environments. The advanced metallurgy and compound formulation deliver outstanding chemical compatibility and mechanical strength, critical for maintaining system integrity in excavators and cold planers subjected to continuous vibration and pressure fluctuations. This OEM-quality seal supports efficient hydraulic performance, reduces downtime, and lowers maintenance costs by preventing premature seal failure.
