Product Description

Product Overview

The 4995554, 3820867, and 3802355 are genuine Cummins exhaust valves, designed as critical auto parts for 6BT diesel engines—a widely trusted engine series used in light to medium-duty commercial vehicles, construction machinery, agricultural equipment, and small industrial generators. As key components of the engine's exhaust system, these valves control the release of combustion gases from the cylinders, directly influencing engine efficiency, emissions, and long-term durability in diverse operating environments.

Part Number	Compatible Engine	Material Composition	Typical Applications
4995554	Cummins 6BT	Nickel-chromium alloy steel	Light commercial trucks, pickup trucks
3820867	Cummins 6BT	Heat-resistant alloy with chrome plating	Construction machinery (backhoes, skid-steers)
3802355	Cummins 6BT	High-strength alloy steel	Agricultural tractors, small industrial generators

Key Features

Genuine OEM Quality: Manufactured to Cummins' strict original equipment standards, these exhaust valves ensure precise fit and performance matching the 6BT engine's specifications. Their authentic design guarantees compatibility with the engine's cylinder head, valve seats, and valve train, eliminating the risks of leaks or premature failure associated with non-genuine parts.
High-Temperature Resilience: Constructed from heat-resistant nickel-chromium alloy steel, these valves withstand extreme exhaust gas temperatures (up to 850°C). The material's excellent thermal stability prevents warping, cracking, or oxidation, even during prolonged high-load operation—critical for 6BT engines in applications like delivery trucks or construction backhoes that face frequent stop-start cycles.
Enhanced Sealing and Wear Resistance: The valve heads are precision-ground to form a tight seal with the valve seats, minimizing exhaust gas leakage and maintaining optimal cylinder pressure. This seal preserves engine power and fuel efficiency, reducing unnecessary fuel consumption by up to 4%. Additionally, the valve stems feature a chrome-plated finish that reduces friction with the valve guide, extending service life and lowering maintenance needs.
6BT-Specific Engineering: Each valve is tailored to the 6BT engine's exhaust flow requirements. 4995554 and 3820867 are optimized for standard 6BT configurations in commercial vehicles, while 3802355 is designed for 6BT variants in agricultural machinery and generators, ensuring reliable performance across all 6BT applications.
