Caterpillar (CAT) 4C-8253 Silicone O-Ring Kit | High-Temp Yellow Seal Box for Excavators

Upgrade your maintenance toolkit with the High-Visibility Yellow 4C-8253 Silicone Kit. This aftermarket replacement for Caterpillar 4C-8253 features premium Yellow Silicone O-rings. Designed for extreme temperature applications where standard black rubber fails, these seals are perfect for cooling systems, torque converters, and transmission groups. The bright yellow color makes it easy to identify seals and spot leaks against dark engine oil or grease.

• OEM Spec Equivalent: Fits all applications requiring CAT Part # 4C-8253.

• High-Temp Silicone Material: The Yellow Silicone (VMQ) construction withstands extreme heat ranges (up to 225°C / 437°F), ensuring durability in hot engine compartments.

• High Visibility: Unlike black rings that disappear in grease, these Yellow rings are easy to see during installation, reducing the chance of missing a seal.

• Chemical Resistance: Excellent resistance to transmission fluids, coolants, and engine oils.

• Comprehensive Set: Includes all standard SAE boss sizes required for Caterpillar heavy equipment maintenance.
