Import Diesel Nozzle 5628945 Bdlla155s681 — Buy in Bulk from Supplier in China

The Diesel Nozzle 5628945 Bdlla155s681 is a high-pressure diesel injector component designed for use in medium-duty truck and industrial engine applications. It features a multi-orifice spray pattern with five precisely drilled holes, each measuring 0.18 mm in diameter, and a nozzle body constructed from high-carbon chrome steel with a hardened surface layer. The component is machined to fit common Bosch and Denso injector housings used in Euro III and IV compliant engines.

This nozzle is typically manufactured using cold forging and precision grinding processes to ensure dimensional consistency. The internal flow channels are electropolished to a surface roughness of Ra 0.2 μm, reducing friction and improving fuel flow stability. While the supplier does not provide material certifications, the alloy composition aligns with SAE 52100 standards for bearing-grade steel, which is common in high-cycle fuel injection components due to its fatigue resistance.

This part is frequently sourced by repair shops servicing construction machinery, marine gensets, and regional transport fleets. Packaging is provided in bulk quantities of 50 or 100 units, sealed in moisture-resistant pouches with anti-rust paper. Lead time is approximately 18-25 days after payment, with FOB Fuzhou as the default trade term. Buyers should confirm compatibility with their injector pump model and request a sample for spray pattern validation before large-scale procurement.

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 with harbor trust status, indicating verified export activity and documented customs clearance history. There is no public information on company size, years in operation, or workforce count, and no certifications such as ISO 9001 or IATF 16949 are referenced in the listing.

The supplier's primary communication channel is via email, with no live customer service or website functionality described. Product listings are maintained through batch uploads of part numbers, suggesting a wholesale-focused, low-touch sourcing model. While the supplier claims quality control processes and global exports, no client names, test reports, or traceability systems are disclosed. Buyers should treat this as a direct manufacturer without third-party verification and validate all technical claims independently.
