Import Diesel Nozzle 5641924 Rdn0sdc6888d — Buy in wholesale FOB from Supplier in China

The Diesel Nozzle 5641924 RDN0SDC6888D is a direct replacement for Cummins ISF and ISB engine models, designed to deliver precise fuel atomization under high-pressure common rail systems. It features a 0.185mm nozzle orifice diameter, a 12mm body thread, and a 2.5mm nozzle tip length, matching OEM dimensional tolerances. The nozzle body is forged from high-strength alloy steel with a hardened surface layer to resist erosion from high-velocity diesel flow.

This component is manufactured using standard industrial practices for diesel injection nozzles, with a typical spray pattern angle of 140 degrees and a needle lift of 0.11mm, consistent with industry norms for medium-duty diesel engines. The internal components are machined to a surface finish of Ra 0.4µm to ensure smooth needle movement and reduce the risk of sticking. While the supplier does not specify material grade, the composition aligns with typical SAE 4140 or equivalent alloy steel used in high-wear fuel injection parts.

This nozzle is primarily purchased by diesel engine rebuilders, fleet maintenance shops, and aftermarket distributors in Southeast Asia, Eastern Europe, and Latin America. Buyers typically order in batches of 50 or more units, with packaging in individual anti-corrosion blister packs inside cartons. Trade terms are FOB Fuzhou Port, with lead times of 15 to 20 days after order confirmation. Buyers should confirm compatibility with their specific engine serial number range before bulk purchase.

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 listed as an imported-tier vendor with harbor-level trust signals, indicating verified export activity but no public certifications or third-party audits. The listing confirms active production of over 30 diesel part numbers, including the RDN0SDC6888D, but provides no information on factory size, workforce, or revenue.

The supplier does not claim ISO certification, IATF compliance, or OEM partnerships. Response metrics show zero recorded response rate and zero average response hours, suggesting limited buyer communication infrastructure. Buyers should treat this as a direct manufacturer without formal quality assurance documentation. Product consistency is implied by the range of part numbers listed, but independent verification of dimensional accuracy and spray performance is strongly advised before bulk procurement.
