Description
Description

Crankshaft seals retain engine oil and prevent external contamination from entering the engine oil system.

Seals designed for dry applications (air-to-fluid interface) typically include a primary lip that prevents engine oil from leaking, and a dust lip. In wet applications (fluid-to-fluid interface), the dust lip is replaced by an auxiliary lip capable of pumping external fluid away from the engine. Some seals have a plastic sleeve to aid in the installation process.

Attributes:
• Air-to-fluid interface
• Cat crankshaft seals are precisely designed to perform in this very demanding application. They must be able to withstand high rotational speeds, elevated temperatures, and high frequency axial motion.
• Cat sealing system uses a robust design, testing, and validation process. Buy the latest Genuine Cat seal to protect your investment.

Warning:This product can expose you to chemicals including Nickel and Nickel compounds, which is known to the State of California to cause cancer, and Perfluorooctanoic acid (PFOA), which is known to the State of California to cause birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
