Caterpillar 081-4819 Oil Seal – OEM-Grade Durability for Paving Compactors

The Caterpillar 081-4819 Seal-Oil (part number 0814819) is a precision-engineered oil seal designed specifically for a range of Caterpillar paving compactors, including models 4PN-PS-300B, 6HM-PF-300B, PFB-PF-300C, 7WD-PF-300, PFS-PS-300C, 7TD-PS-300, and 7XD-PS-500. Manufactured using high-grade elastomeric materials combined with robust metal reinforcement, this seal ensures optimal resistance to wear, heat, and harsh load conditions typically encountered in heavy-duty compaction operations. Its exact dimensions and tight tolerances guarantee a perfect fit within the drivetrain and hydraulic systems, preventing oil leakage and contamination, which are critical for maintaining machine efficiency and longevity.

Technically, the 081-4819 oil seal features advanced sealing lip geometry that enhances its ability to withstand high rotational speeds and pressure differentials common in paving compactors. The metallurgy of the metal casing provides structural integrity, while the elastomeric compound offers excellent chemical resistance against hydraulic fluids and environmental contaminants. This combination results in superior sealing performance, reduced downtime, and extended service intervals. Using an OEM-grade seal like the Caterpillar 081-4819 ensures compatibility with original equipment specifications, preserving the machine’s operational reliability and resale value.
