6CT SET:

---Valve guide oem: 3923564 / 3901187

---Intake valve seat oem: 3924582

---Exhaust valve seat oem: 3924583

Engineered to meet Cummins' exacting standards, these OEM-grade valve seats (#3924583 intake / #3924582 exhaust) deliver reliable performance for 6CT engines operating in severe conditions. The matched intake and exhaust seats work in concert to maintain optimal combustion chamber integrity throughout extended service intervals.

Advanced Material Composition:

The exhaust valve seat utilizes a nickel-chromium-molybdenum alloy specifically formulated to withstand continuous 850°C (1562°F) temperatures while resisting thermal fatigue. The intake seat features a copper-iron composite matrix that combines excellent thermal conductivity with superior machinability for perfect surface finishes.

Performance-Enhancing Features:

1. Extended Service Life – The exhaust seat's alloy structure demonstrates 35-40% greater wear resistance than conventional materials, significantly reducing maintenance frequency in heavy-duty applications.

2. Optimized Heat Transfer – The intake seat's copper-rich composition provides:

   • 30% improved heat dissipation

   • More stable valve clearances during temperature fluctuations

   • Reduced thermal stress on cylinder heads

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

   • Complete valve-to-seat contact

   • Consistent compression retention

   • Minimized gas leakage

Technical Specifications:

• Hardness: 45-50 HRC (exhaust), 35-40 HRC (intake)

• Temperature Range: -30°C to 900°C (exhaust)

• Concentricity: 99.5% minimum

Ideal Applications:

• Medium-duty trucking

• Construction equipment

• Agricultural machinery

• Industrial power units

• Marine auxiliary systems

Documented Performance Benefits:
Field testing confirms:
• 30-35% longer valve service intervals
• 4-6% improved fuel efficiency
• Reduced cylinder head temperatures
• Lower maintenance costs

These Cummins 6CT valve seats provide OEM-quality performance with enhanced durability for demanding operating conditions. The exhaust seat's molybdenum-enhanced alloy offers exceptional protection against thermal stress in turbocharged applications, while the intake seat's optimized heat transfer characteristics promote stable valve operation across all load conditions.
