Key Features

• Genuine OEM Sealing Material — Manufactured to original compression and material specifications, delivering the same leak-resistance as the factory-installed packing.
• Drop-In Head Cover Fit — Engineered to seat directly in the head cover groove without trimming or reshaping, maintaining proper gasket contact across the sealing surface.
• Broad Cross-Equipment Compatibility — Fits MVC and MVH plate compactors, MC and EC concrete mixers, WM mortar mixers, walk-behind trowels, masonry saws, centrifugal and diaphragm pumps, and portable generators across the Multiquip product line.
• Maintains Oil and Vapor Containment — A correctly seated head cover packing keeps engine oil and combustion vapors contained, protecting internal engine components from contamination and preventing external leaks.
• Long-Term Compression Resistance — OEM-grade packing material resists heat cycling and sustained compression, holding its seal even after repeated thermal expansion and contraction across extended run cycles.

The head cover packing forms the seal between the valve or head cover and the engine block, preventing engine oil and vapors from escaping around the cover joint. When this packing hardens, cracks, or compresses unevenly over time, oil leaks develop at the head cover and engine performance can be compromised by contamination of surrounding components. Replacing the packing with a correct-specification part restores a tight, consistent seal and keeps the engine running clean.
