Elring 472.230 Seal Set, valve stem

Elring 472.230 Seal Set – Valve Stem

The Elring 472.230 Seal Set is a comprehensive collection of high‑performance gaskets and seals designed specifically for the valve stem assembly in automotive engines. This kit ensures optimal sealing, reduces leakage, and enhances overall engine reliability.

Key Components Included

• Valve Stem Seal (Gasket) – Provides a tight seal between the valve stem and the cylinder head, preventing oil or coolant leaks.
• Valve Stem Sealing Ring – Maintains pressure integrity during engine operation, accommodating thermal expansion.
• Sealant Kit (Optional) – Includes high‑temperature sealant for additional protection against fluid ingress.
• Installation Instructions – Step‑by‑step guide to ensure correct placement and torque specifications.

Material Composition

The gasket material is a proprietary blend of high‑temperature silicone rubber combined with reinforced fibers. This composition offers:

• Excellent resistance to engine oil, coolant, and combustion gases.
• Flexibility at low temperatures and rigidity at high temperatures.
• Long service life even under aggressive operating conditions.

Compatibility Overview

The Elring 472.230 Seal Set is engineered to fit a wide range of vehicle models, including but not limited to:

• Toyota Yaris II (3/5‑door)
• Daihatsu Terios I
• Subaru models with similar valve stem dimensions

Its universal design allows it to be used in both domestic and international markets, making it a versatile choice for mechanics worldwide.

Installation Procedure

1. Preparation: Remove the old valve stem seal and clean the mating surfaces with a solvent to eliminate debris.
2. Seal Placement: Position the new gasket onto the valve stem, ensuring it sits flush against the cylinder head.
3. Sealing Ring Installation: Slide the sealing ring over the valve stem, aligning it with the designated groove.
4. Tightening: Use a torque wrench to tighten the valve stem bolts to the manufacturer’s specified torque value.
5. Sealant Application (Optional): Apply the provided sealant around the gasket edges for added protection.
6. Final Check: Inspect the assembly for any gaps or misalignments before reassembling the engine block.

Performance Benefits

• Leak Prevention: The gasket’s superior sealing properties eliminate oil and coolant leaks, preserving engine efficiency.
• Thermal Stability: Maintains integrity across a wide temperature range, preventing seal failure during high‑heat operation.
• Reduced Maintenance Costs: By extending the life of the valve stem assembly, it reduces the frequency of repairs and replacements.
• Improved Engine Longevity: Consistent sealing conditions help maintain optimal compression ratios, contributing to longer engine life.

Quality Assurance

Elring employs rigorous testing protocols for each seal set. Every component undergoes:

• Pressure tolerance tests up to 2000 psi.
• Temperature cycling between -40°C and +250°C.
• Chemical resistance evaluation against common automotive fluids.

These standards ensure that the Elring 472.230 Seal Set delivers reliable performance in demanding engine environments.

Maintenance Tips

• Inspect valve stem seals during routine maintenance to catch early signs of wear.
• Avoid using abrasive cleaners that could damage gasket surfaces.
• Store spare kits in a dry, temperature‑controlled environment to preserve material integrity.

Conclusion

The Elring 472.230 Seal Set – Valve Stem is an essential component for any automotive repair or overhaul project involving valve stem assemblies. Its robust construction, universal compatibility, and proven performance make it a trusted choice among mechanics and vehicle owners alike.
