Elring 724590 Seal, Valve Stem

Elring 724590 Valve Stem Seal

The Elring 724590 is a high‑performance Valve Stem Seal designed to provide reliable sealing for the intake and exhaust sides of engine valves. Crafted from premium FPM (Fluorinated Rubber), this seal delivers exceptional resistance to oil, fuel, and high temperatures while maintaining flexibility across a wide operating range.

Key Features

• Material Excellence: Made from FPM (Fluorinated Rubber), the seal resists degradation from oil, fuel, and high‑temperature environments typical of modern internal combustion engines.
• Color & Finish: Finished in a durable black coating that protects against UV exposure and oxidation, ensuring long‑term performance.
• Precision Engineering: Manufactured to exact tolerances, the seal fits seamlessly onto valve stems of various engine configurations, including those found in Audi, VW, Porsche, Seat, Skoda, and many other OEMs.
• Dual‑Side Compatibility: Suitable for both intake and exhaust sides, providing comprehensive protection against oil leakage and combustion gases.
• Easy Installation: Designed with a smooth surface that allows quick removal of the valve stem without damaging surrounding components.

Applications & Compatibility

The Elring 724590 is engineered to match a broad spectrum of engine models. Its versatility makes it an ideal replacement for OEM seals in:

• Audi (including A1–A8, RS4/RS5, and various model years)
• Volkswagen (Golf, Passat, Polo, Touareg, etc.)
• Porsche (2.0L, 3.0L engines)
• Seat & Skoda (A3, A4, Octavia, etc.)
• Bentley, Chrysler, Cupra, and other premium brands that use similar valve stem designs.

Engineers often select the Elring 724590 for its proven track record in high‑performance applications where oil leakage can compromise engine efficiency or cause damage to critical components.

Installation Guidelines

1. Remove the old valve stem seal carefully, ensuring no debris remains on the valve stem.
2. Clean the valve stem surface with a suitable solvent to remove oil residue and contaminants.
3. Inspect the valve stem for wear or damage; replace if necessary before installing the new seal.
4. Slide the Elring 724590 onto the valve stem, aligning it with the engine’s orientation (intake vs. exhaust).
5. Reinstall the valve stem into the cylinder head, ensuring proper seating of the seal against the valve seat.
6. Torque the valve stem bolts to manufacturer specifications to guarantee a secure fit and optimal sealing pressure.

Performance Benefits

• Oil Control: Prevents oil from leaking into the combustion chamber, preserving compression ratios and reducing emissions.
• Fuel Resistance: Maintains integrity when exposed to gasoline or diesel, preventing seal degradation.
• Temperature Stability: Withstands temperatures up to 200°C (or higher depending on engine design) without losing elasticity.
• Longevity: Designed for extended service life, reducing the frequency of maintenance intervals.

Maintenance & Inspection Tips

Regular inspection during routine engine overhauls can catch early signs of seal wear. Look for:

• Visible cracks or hardening on the seal surface.
• Oil seepage around the valve stem area.
• Unusual noise indicating a loose or damaged seal.

Replacing the Elring 724590 at the first sign of wear ensures continued engine reliability and protects against costly repairs.
