4W7019 Injector Nozzle Detailed Introduction

Product Core Features

• Precision Atomization & Efficient Combustion: The 4W7019 nozzle adopts precision laser-drilled spray holes (0.15-0.20 mm in diameter) to achieve molecular-level uniform atomization, matching the optimized cone spray pattern to ensure full fuel combustion. This design not only improves combustion efficiency but also effectively reduces carbon deposition and exhaust emissions, meeting environmental protection requirements while enhancing engine performance.
• Premium Material & Durable Performance: Made of high-strength alloy steel, the 4W7019 injector nozzle undergoes strict vacuum hardening treatment, featuring excellent high temperature resistance, corrosion resistance and wear resistance. It can stably operate under the high pressure of 1400-1600 bar, with low failure rate and long service life, reducing the frequency of parts replacement for customers.
• Perfect Compatibility & Direct Replacement: Specifically compatible with CAT C7, C9, 3408, 3412 series engines, as well as CAT D9L, D9N, D10N bulldozers and EC series excavators, the 4W7019 is a direct OEM replacement part with precise size and strict tolerance control, enabling plug-and-play installation without additional modifications or adjustments.
• Strict Quality Control & Reliable Assurance: Compliant with CAT original quality standards, each 4W7019 injector nozzle undergoes rigorous testing before leaving the factory, covering flow rate, injection pressure, sealing performance and other indicators, ensuring stable and consistent performance in various harsh working conditions of engineering machinery. It is available as a new genuine part or high-quality OEM-equivalent, with a standard 6-12 month warranty for worry-free use.
• Bulk Supply & Customizable Service: For B2B buyers, we provide stable bulk wholesale support with favorable prices, meeting the large demand of parts distributors and maintenance enterprises. At the same time, we offer customized packaging and LOGO services to meet the personalized needs of different business scenarios, enhancing the competitiveness of our customers’ products.
