Elring 373.490 Seal Ring

Elring 373.490 Seal Ring

The Elring 373.490 Seal Ring is a high‑performance sealing component designed for the crankshaft oil seal application in a wide range of automotive engines. Manufactured by Elring, a leading supplier of precision seals and gaskets, this part delivers reliable protection against oil leakage, ensuring optimal engine performance and longevity.

Key Features

• Material: Fluoro‑Rubber (FPM) – offers excellent resistance to high temperatures, oils, and chemicals commonly found in crankshaft environments.
• Design: Dual‑lip seal ring with a precision‑cut groove that provides a tight fit against the crankshaft flange or transmission end.
• Dimensions: Standard size compatible with most OEM specifications for rear crankshaft oil seals.
• Application: Engine crankshaft, transmission end, and gearcase sealing in vehicles such as Mazda, Ford, Kia, Suzuki, Nissan, Hyundai, and many others.
• Installation: Easy to install with standard seal removal tools; designed for quick replacement during routine maintenance or repair.

Compatibility Overview

The Elring 373.490 Seal Ring is engineered to fit a broad spectrum of vehicle models and engine types. Below are some representative applications, translated into English where necessary:

• Mazda 5 (CR) 2.0 – 2005‑201
• Ford Mazda – various model years
• Kia Besta – 4‑door sedan models
• Hyundai – selected engine families
• Suzuki, Nissan, and other Asian manufacturers (e.g., Anfini, Asia Motors)
• Transmission end seals for Ford, Chevrolet, and other global brands

Because the seal ring is a universal component, it can be used in any vehicle that requires a rear crankshaft oil seal with matching dimensions. Always verify OEM specifications before installation.

Performance Benefits

• Oil Retention: Maintains a tight seal against the crankshaft, preventing oil seepage into the transmission or gearbox.
• Durability: Fluoro‑Rubber construction resists wear and degradation at temperatures up to 200 °C.
• Reduced Maintenance: By sealing effectively, it reduces the frequency of oil leaks and associated maintenance tasks.
• Engine Protection: Keeps contaminants out of critical engine components, extending service life.

Installation Guidelines

1. Remove the old seal ring carefully using a suitable seal removal tool to avoid damaging the crankshaft flange.
2. Clean the mating surfaces with an appropriate solvent to remove oil residue and debris.
3. Inspect the new Elring 373.490 Seal Ring for any manufacturing defects before installation.
4. Insert the seal ring into the groove, ensuring it sits flush against the flange without twisting.
5. Reinstall the crankshaft or transmission assembly and torque to manufacturer specifications.

Quality Assurance

The Elring 373.490 Seal Ring undergoes rigorous testing during production, including:

• Dimensional accuracy checks against OEM tolerances.
• Material composition verification to ensure FPM purity and consistency.
• Pressure and temperature endurance tests simulating real‑world operating conditions.

These quality controls guarantee that each seal ring delivers reliable performance from the first use.

Maintenance Tips

• Inspect seals during routine oil changes or when symptoms of oil leakage appear.
• Avoid using harsh chemicals on the seal surface; mild solvents are sufficient for cleaning.
• Store spare seal rings in a cool, dry environment to preserve material integrity.

Conclusion

The Elring 373.490 Seal Ring is an essential component for maintaining engine oil integrity across a wide array of vehicles. Its robust FPM construction, universal fitment, and proven performance make it the preferred choice for mechanics and automotive enthusiasts alike.
