Brand Caterpillar
Engine C15
Fuel Oil

Precision-engineered for Caterpillar's C15 engine platform, these OEM-specified valve seats (#2803979 intake / #2265561 exhaust) deliver exceptional durability and thermal management in the most demanding operating conditions. These critical components maintain perfect valve-to-seat contact under extreme pressures and temperatures, ensuring optimal combustion efficiency throughout extended service intervals.

Advanced Material Technology:

The exhaust valve seat (2265561) features a proprietary high-nickel chromium alloy with tungsten reinforcement, specifically formulated to withstand continuous 900°C (1652°F) exhaust gas temperatures while resisting thermal fatigue and oxidation. The intake seat (2803979) utilizes a copper-beryllium iron matrix that combines superior heat transfer properties with excellent machinability for precision surface finishes.

Performance Advantages:

  1. Extended Service Life – The exhaust seat's multi-phase alloy structure demonstrates 45% greater wear resistance than conventional materials in high-hour mining and heavy haul applications.

  2. Enhanced Thermal Management – The intake seat's copper-rich composition provides:

    • 30% better heat dissipation than standard iron seats

    • More stable valve clearances during thermal cycling

    • Reduced hot spotting in the combustion chamber

  3. Precision Sealing Surfaces – CNC-machined to 0.5μm Ra surface finish ensures:

    • Complete 360° valve contact

    • Consistent compression ratios

    • Minimized blow-by across all load conditions

Technical Specifications:

  • Exhaust Seat Material: Ni-Cr-W-Mo superalloy

  • Intake Seat Material: Cu-Be-Fe composite

  • Hardness: 48-52 HRC (exhaust), 38-42 HRC (intake)

  • Temperature Range: -40°C to 950°C (exhaust)

  • Concentricity: 99.6% minimum

Critical Applications Include:

  • Over-the-road trucking (long-haul and heavy haul)

  • Mining and quarry equipment

  • Marine propulsion systems

  • Industrial power generation

  • Oil field service operations

Verified Operational Benefits:
Field testing demonstrates:
• 35-40% longer valve service intervals
• 5-7% improved fuel efficiency through superior sealing
• Reduced cylinder head temperatures in turbocharged configurations
• Lower total cost of ownership through extended overhaul periods

These Caterpillar C15 valve seats represent the pinnacle of materials engineering for severe-service applications. Available in standard configurations with options for oversized repairs or performance enhancements, they deliver OEM-equivalent reliability with the durability demanded by 24/7 industrial operations. The exhaust seat's tungsten-enhanced alloy matrix provides exceptional protection against the extreme temperatures encountered in modern high-efficiency engine designs.
