Elring 026.640 Seal, Valve Stem

Product Overview

The Elring 026.640 Seal, Valve Stem is a precision-engineered component designed to provide reliable sealing for valve stems in automotive engines. Crafted from high-performance fluorinated rubber (FPM), it delivers exceptional resistance to heat, oil, and combustion gases, ensuring long-term durability under demanding operating conditions.

Key Features

• Material Excellence: Made from FPM, the seal offers superior chemical resistance and maintains elasticity at temperatures up to 200 °C.
• Exact Fit: The inner diameter is calibrated to match standard valve stem sizes, guaranteeing a snug fit without the need for additional tooling.
• Low Friction: The smooth surface reduces wear on the valve stem, extending component life and improving engine efficiency.
• Corrosion Resistance: The seal’s composition resists oxidation, preventing degradation in high-humidity or corrosive environments.
• Versatile Compatibility: Suitable for a wide range of Ford models, including the Fiesta, Focus, and Fusion series, as well as other OEMs that use similar valve stem dimensions.

Technical Specifications

Installation Guidelines

1. Preparation: Clean the valve stem thoroughly to remove oil, dirt, and old seal material.
2. Alignment: Position the seal so that its inner diameter aligns perfectly with the stem.
3. Insertion: Gently slide the seal onto the stem, ensuring no twists or kinks form.
4. Securing: If required, use a torque wrench to apply the manufacturer’s recommended tightening sequence.
5. Verification: Inspect for any gaps or misalignments before reassembling the valve assembly.

Maintenance Tips

• Inspect seals during routine engine overhauls for signs of wear or cracking.
• Avoid exposure to extreme temperatures beyond the specified range, as this can accelerate degradation.
• Use compatible lubricants that do not contain additives harmful to fluorinated rubber.
• Store unused seals in a cool, dry place away from direct sunlight to preserve material integrity.
