• Precision Engineering: Tolerances engineered to match OEM specifications, ensuring a perfect fit on both intake and exhaust sides of the valve stem.
• Durability: Designed for long service life even under aggressive operating conditions such as turbocharged or high‑performance engines.
• Versatile Compatibility: Suitable for a broad range of vehicle makes and models, including Opel, Vauxhall, Bitter, Chevrolet, DaeWoo, Holden, Toyota, and many others.
• Easy Installation: Standard size and shape allow straightforward replacement without the need for special tools or modifications.

Technical Specifications

Applications

The ELRING 702.951 is engineered for use in:

• Internal combustion engines with both intake and exhaust valve stems.
• Turbocharged and naturally aspirated powertrains where oil leakage can compromise performance.
• High‑temperature environments such as racing, heavy‑duty commercial vehicles, and off‑road applications.

Installation Guide

1. Remove the old valve stem seal by carefully pulling it out of the cylinder head. Ensure no debris remains in the sealing groove.
2. Clean the valve stem and surrounding area with a solvent compatible with engine oils to remove grease, oil, or residue.
3. Insert the new ELRING 702.951 into the groove, aligning it precisely with the valve stem. Use gentle pressure to seat the seal without damaging the rubber.
4. Reinstall the valve stem and complete the engine assembly according to manufacturer specifications.
5. Perform a leak test after startup to confirm proper sealing.

Benefits of Choosing ELRING 702.951

• Reduced Oil Consumption: A tight seal prevents oil from leaking into the combustion chamber, maintaining optimal engine performance and fuel efficiency.
• Extended Engine Life: By protecting valve stems from excessive wear and corrosion, the seal contributes to longer service intervals.
• Consistent Performance: The FPM material maintains flexibility across a wide temperature range, ensuring reliable operation in both cold starts and high‑heat conditions.
• Cost Effectiveness: Durable construction reduces the frequency of replacements, saving maintenance costs over time.
