Seal, Oil Filter Adapter – Mopar (53021661AA)

The Mopar Oil Filter Adapter Seal (53021661AA) is a Genuine OEM engine sealing component designed to create a secure seal between the oil filter adapter and the engine assembly. This seal plays an essential role in maintaining the integrity of the engine’s lubrication system by preventing oil leaks at the oil filter adapter mounting surface. Manufactured according to Mopar’s strict factory engineering standards, the oil filter adapter seal ensures dependable sealing performance and proper engine lubrication.

Constructed from high-quality heat- and oil-resistant synthetic rubber, the seal is engineered to withstand continuous exposure to engine oil, pressure fluctuations, and high operating temperatures. The flexible sealing material compresses evenly when installed, forming a tight barrier that helps prevent oil seepage while maintaining consistent sealing under engine vibration and thermal expansion.

The 53021661AA oil filter adapter seal is engineered as a vehicle-specific direct-fit component, matching the original seal dimensions, profile, and sealing surfaces used in Mopar factory lubrication systems. Maintaining OEM specifications is essential to ensure proper sealing pressure and compatibility with the oil filter adapter and engine block interface. Aftermarket seals that do not meet factory tolerances may lead to oil leaks or installation challenges.

For professional technicians, installing a Genuine Mopar oil filter adapter seal ensures that engine service maintains factory lubrication system sealing standards and reliable engine operation. For experienced DIY vehicle owners, selecting the OEM seal simplifies installation since it fits precisely into the adapter sealing groove and aligns with the engine mounting surface without requiring modification.

A properly functioning oil filter adapter seal helps maintain oil containment within the engine lubrication system while supporting proper oil flow through the filter assembly. Replacing a worn or damaged seal helps restore proper sealing and protect the engine from oil leaks.

• Genuine Mopar OEM oil filter adapter seal

• Heat- and oil-resistant synthetic rubber construction

• Designed to seal the oil filter adapter to the engine

• Helps prevent engine oil leaks
