For 114-2687 1142687 O-ring oil seal CAT C15 C18 3306 3406 Excavator Engine Parts

Specification

Description

This product is an O-ring seal compatible with part numbers 114-2687 and 1142687, serving as a critical sealing component for excavator engines (including C15, C18, 3306, 3406 models). Precision-molded from high-elasticity rubber material, it is mainly used for sealing the engine oil system to prevent oil leakage and block external impurities, ensuring stable lubrication and operation inside the engine.

Advantage

Precise Fit: Manufactured to strict original equipment dimension standards, it fits perfectly with corresponding engine oil system interfaces, enabling easy installation without additional modifications.
Oil and Corrosion Resistance: Made from a special rubber formula resistant to mineral oil and aging, it can withstand long-term exposure to engine oil, diesel fuel, and chemical substances in the engine compartment.
High Elasticity and Resilience: Excellent elastic recovery performance maintains a tight seal under sustained pressure and temperature fluctuations, resisting permanent deformation.
Long-Life Design: Outstanding tear and wear resistance effectively extends the sealing cycle, reducing downtime for maintenance and lowering operational costs.
Reliable Protection: Bidirectional sealing structure prevents internal fluid leakage while blocking contaminants like dust and moisture, safeguarding core engine components.

Performance

Operating Temperature Range: Stable performance from -40°C to 120°C, adapting to the engine's thermal cycling conditions.
Pressure Resistance: Withstands the normal operating pressure of the engine oil system and maintains sealing integrity under peak pressure.
Material Hardness: Moderate Shore hardness balances seal conformability and extrusion resistance, preventing intrusion into gaps under high pressure.
Aging Resistance: Passes accelerated aging tests, retaining excellent physical properties in high-temperature environments for long-lasting sealing performance.
Dimensional Accuracy: Tolerances controlled to high industry standards, ensuring precise fit with sealing grooves and eliminating leakage caused by dimensional deviations.
