The Kibblewhite 10-HC518 is a precision-engineered KPMI® high chrome alloy valve seat designed for professional engine rebuilds. With a 2.040" outer diameter, this valve seat is machined from solid bar stock and ground to exacting tolerances for superior performance and longevity.

Key Features:

• 18-22% chromium content provides exceptional resistance to abrasion, corrosion, and high-temperature deformation
• 1-2% nickel content enhances corrosion resistance and overall material toughness
• Machined from solid bar stock, not powder metal, for superior strength and consistency
• Machines as a continuous chip for easier installation and precise fitting
• Ground to exacting tolerances for optimal sealing and valve train performance
• Suitable for both gasoline and diesel engine applications

KPMI® high chrome valve seats are the professional's choice for engine rebuilds where durability and precision matter. The solid bar stock construction offers significant advantages over powder metal alternatives, including better machinability and more consistent material properties throughout the seat.
