Elring 238.490 Spark Plug Tube Seal

The Elring 238.490 Spark Plug Tube Seal is a precision-engineered sealing component designed to prevent oil leaks around spark plug tubes in the valve cover. This rubber or silicone gasket sits at the top of the spark plug tube, preventing engine oil from leaking into the tube and onto the spark plugs. Manufactured from tailor-made elastomer compounds to ensure excellent functionality and a long service life, this seal maintains proper engine performance by keeping the ignition system clean and dry.

Key Features:

• OEM-quality construction meeting original equipment standards
• Premium elastomer material designed to withstand extreme engine temperatures and oil exposure
• Precision fit ensures reliable, leak-free sealing
• Prevents oil contamination of spark plugs and ignition components
• Direct replacement part for worn or damaged seals

Over time, spark plug tube seals can harden or crack due to heat and oil exposure, requiring replacement to prevent misfires and oil contamination. Common symptoms of seal failure include oil pooling in spark plug wells, engine misfires, and visible oil seepage around the valve cover area. Elring is known as an OEM supplier to many automobile manufacturers, delivering the same quality parts used in original vehicle assembly. Regular replacement of deteriorated spark plug tube seals helps maintain optimal engine performance and prevents costly ignition system damage.
