Product Features
The Cummins fuel injector 3076132 serves as a core component of the fuel systems for heavy-duty diesel engines, compatible with engine series such as the KTA19, QSL9, and QSK19. This injector features a 4-hole closed-type design with a nozzle hole diameter of approximately 0.35 mm and an injection pressure of no less than 17.5 MPa. By utilizing a high-precision needle valve assembly (with a mating clearance of 0.001–0.0025 mm) and a 150° spray cone angle, it achieves highly efficient fuel atomization and stable combustion. Manufactured from high-quality alloy steel and processed using precision grinding techniques, this injector is designated as an Original Equipment Manufacturer (OEM) replacement part for Cummins engines.

About Us
FAQ
Q: 1. Can the 3076132 fuel injector be mixed with non-OEM parts? Why must it be replaced in pairs?
A: It must not be mixed with other parts or replaced individually. This is because the needle valve and the valve body are high-precision, matched-ground components with a tolerance of 0.001–0.0025 mm. Any substitution will compromise the sealing integrity and injection consistency, leading to poor atomization, fuel leakage, or combustion imbalance. The entire assembly must be replaced as a unit to ensure stable performance regarding high-pressure injection (≥17.5 MPa) and the 150° spray cone angle.
Q: 2. Which engines and operating conditions is this fuel injector suitable for? What are its core advantages?
A: It is specifically designed for heavy-duty diesel engines such as the Cummins KTA19, QSL9, and QSK19. It is well-suited for high-load operating environments, including mining vehicles, heavy-duty trucks, and generator sets. Its core advantages lie in its 4-hole closed-type structure, paired with 0.35 mm precision nozzle holes, which achieves highly efficient fuel atomization. Furthermore, the use of high-quality alloy steel combined with precision grinding processes ensures exceptional resistance to high temperatures and wear, resulting in a service life exceeding 20,000 hours.
Q: 3. What is the HS Code for exporting the 3076132 fuel injector? Is it classified as a hazardous material?
A: The internationally recognized HS Code is 8409999990, classified under "Parts of fuel injection devices for other internal combustion engines." This product is a purely metallic mechanical component; it contains no flammable, corrosive, or toxic substances and is explicitly classified as a non-hazardous material, allowing for safe air and sea freight.
Q: 4.How should the product be packaged for international shipping to ensure safe arrival?
A: It is packaged in three layers: the inner layer is sealed with an anti-static bag, the middle layer is fixed with foam in a hard plastic box, and the outer layer is an IATA standard corrugated carton or wooden box, marked with "precision instrument", "moisture-proof" and "upward". The total weight of each box is ≤40kg.
