Federal Mogul Spark Plug Tube Seal

Federal-Mogul spark plug tube seals (also called spark plug well seals or valve cover spark plug tube seals) keep engine oil out of the spark plug wells. They seal the joint between the valve cover and the spark plug tube. This helps prevent oil from fouling spark plugs and ignition components, which can cause misfires and rough running.

Key Features:

• Seals the spark plug tube opening in the valve cover to stop oil leaks into the plug well
• Helps protect spark plugs, boots and coil connections from oil contamination
• Made with durable sealing material designed to handle engine heat and oil exposure
• Built to meet the quality standards of Federal-Mogul, a long-established supplier of engine sealing and powertrain components
• Usually replaced along with the valve cover gasket when servicing the valve cover

Replacing worn or hardened tube seals restores a tight seal at the valve cover. It helps prevent oil leaks and keeps the ignition system running reliably. Select the correct child item for your application from the options in this product group.
