Import Diesel Injector Nozzle Dlla160snd249 — Buy in Bulk from Supplier in China

The Diesel Injector Nozzle DLLA160SND249 is a direct replacement component designed for high-pressure common rail diesel engines, matching the original equipment dimensions and spray pattern. It features a precision-machined nozzle body with five spray holes, each 0.18mm in diameter, and a needle lift of 0.12mm, consistent with Bosch and Denso OEM standards for this model. The nozzle is manufactured from hardened tool steel with a surface hardness of 58-62 HRC to withstand prolonged exposure to high-temperature fuel and combustion pressures.

This component is typically made from high-grade martensitic stainless steel with a chromium-nickel-molybdenum alloy composition, offering resistance to corrosion and thermal fatigue. It is commonly used in Euro IV and Euro V compliant engines found in commercial trucks and agricultural machinery. The nozzle tip is finished with a plasma-sprayed tungsten carbide coating to reduce wear and maintain spray geometry over extended service intervals. While the supplier does not provide certification documents, the manufacturing process aligns with standard diesel injection nozzle production practices in China's Fujian industrial zone.

Buyers commonly use this nozzle in aftermarket repair kits for Iveco, MAN, and DAF trucks, as well as in rebuild programs for industrial generators. The component is sold individually or in batches of 10 or more, with packaging in sealed anti-corrosion bags and cardboard inserts. Trade terms are typically FOB Fuzhou Port, with lead times of 15 to 25 days after payment confirmation. Buyers should verify compatibility with their engine model using the OEM part number before ordering.

Chen Chen Diesel Parts Plant operates from Fuzhou, Fujian Province, and specializes in manufacturing diesel fuel injection components including nozzles, plungers, and delivery valves. The supplier is classified as imported and harbor-trusted, indicating verification of physical address and export activity, though no formal certifications are listed. Their product range includes over 30 distinct nozzle models, suggesting established production capability, but there is no public information on company size, revenue, or client names.

The supplier's listing shows active export history and a focus on diesel injection parts, with consistent part numbering across multiple product lines. There are no claims about ISO certification, laboratory testing, or OEM partnerships. Response metrics are not available, indicating no active communication channel on the platform. Buyers should treat this as a manufacturer with documented production capacity but unverified quality assurance processes, and must validate performance through physical inspection or third-party testing before bulk orders.
