Engineered specifically for Cummins K6, K19, QSK19G, and G19 series engines, this comprehensive intake and exhaust valve seat set (P/N: 3086192 & 3086193) delivers critical sealing performance under extreme combustion conditions. These precision components form the essential sealing surface between valves and cylinder heads, maintaining compression ratios, optimizing heat transfer, and preventing gas leakage in high-output diesel applications. Manufactured to exact Cummins specifications, this matched set ensures perfect compatibility and reliable performance in heavy-duty trucking, power generation, and industrial equipment.
Precision Engineering for Optimal Performance
Every seat undergoes CNC machining to achieve micron-level tolerances, guaranteeing perfect concentricity and surface finish for uniform valve contact. The precisely calculated interference fit maintains secure seating under thermal cycling, while the specialized seat angles promote efficient gas flow and combustion stability. This attention to dimensional accuracy translates directly to improved fuel efficiency and reduced emissions by maintaining ideal compression ratios throughout the engine's operational range.
Enhanced Durability Features
The exhaust seats incorporate advanced copper-nickel infiltration within the base material, creating a self-lubricating microstructure that reduces micro-welding between the seat and valve face. This proprietary technology extends component life by preventing adhesion wear – particularly valuable in engines operating with alternative fuels or extended oil change intervals. Both intake and exhaust seats feature laser-etched identification marks to prevent installation errors and streamline maintenance procedures.
Professional Installation Guidelines
For optimal performance, valve seat installation requires precision machining of the cylinder head to achieve specified interference fits. Always replace intake and exhaust seats as matched sets to maintain balanced heat dissipation across the cylinder head. Recommended valve seat recession checks every 5,000 operating hours for preventive maintenance. Pair with genuine Cummins valves and guides for complete valve train reliability.
