Federal Mogul ES 72477 Spark Plug Tube Seal Set

The Federal Mogul ES 72477 is a Spark Plug Tube Seal Set (SPTSS) designed to prevent oil leaks from migrating into the spark plug wells. These seals fit between the valve cover and the spark plug tubes, creating a reliable barrier against oil intrusion that can foul spark plugs and cause misfires or ignition failure.

Manufactured by Federal Mogul — a globally recognized leader in engine sealing technology — these tube seals are engineered to meet or exceed OEM specifications for a precise, leak-free fit. The seals are constructed from high-quality elastomeric materials capable of withstanding the high temperatures and chemical exposure found in the valve cover area.

Key Features:

• Seals the spark plug tube-to-valve cover interface to stop oil leaks
• Manufactured to OEM specifications for proper fit and function
• High-temperature elastomeric material resists heat, oil, and engine fluids
• Helps prevent oil fouling of spark plugs and ignition components
• Direct replacement for worn or damaged OEM spark plug tube seals
• Sold as a set to cover all cylinders in a single service

Replacing these seals during a valve cover gasket service or spark plug replacement is recommended to ensure a complete, long-lasting repair. The ES 72477 is a trusted Federal Mogul part number for technicians and DIY enthusiasts seeking a quality sealing solution.
