Buy & Import Diesel Injector Nozzle 5621713 Lls50-6666 from Chen Chen Diesel Parts Plant - Wholesale Supply

This diesel injector nozzle, model 5621713 Lls50-6666, is a direct replacement for Cummins and other heavy-duty diesel engines. It is manufactured as a standalone component for use in remanufactured or aftermarket fuel systems. The nozzle features a multi-hole design with precision-drilled orifices to ensure consistent fuel atomization under high-pressure common rail conditions.

The body is forged from high-carbon chromium steel, hardened to 58-62 HRC for wear resistance. Orifice diameters are laser-drilled to 0.12 mm with a tolerance of ±0.003 mm. Typical industry standards for this nozzle type allow a maximum deviation of 0.005 mm in orifice size. The surface finish is ground to Ra 0.4 µm to reduce carbon buildup and improve fuel flow consistency.

This nozzle is used by diesel engine rebuilders, aftermarket parts distributors, and industrial equipment service centers in Southeast Asia, Africa, and Latin America. Units are sold in bulk packs of 10 or 25. Packaging is sealed in anti-rust paper with individual foam inserts. Trade terms are FOB Fuzhou, with lead time of 7 to 10 days after payment. No warranty is stated.

Frequently Asked Questions About Diesel Injector Nozzle 5621713 Lls50-6666 from Chen Chen Diesel Parts Plant
The orifice diameter is controlled to ±0.003 mm. This tight tolerance ensures consistent fuel delivery and prevents misfire or incomplete combustion. Buyers should request laser measurement reports for batch samples. Tolerances exceeding ±0.005 mm are considered out of spec in most OEM applications.

Sourcing Diesel Injector Nozzle 5621713 Lls50-6666 from Chen Chen Diesel Parts Plant - China Import Guide

Before ordering, confirm the nozzle part number matches your injector housing. Request a sample unit for fit and flow testing. Verify the orifice diameter and surface finish with a micrometer and profilometer. Do not accept units without visible part marking or batch code. Counterfeit nozzles often have blurred engraving or incorrect material hardness.

Lead time is typically 7 to 10 days after payment. Incoterms are FOB Fuzhou Port. Payment is required in full via T/T before shipment. Packaging is bulk in cardboard boxes with no custom labeling. Buyers should request a packing list with part numbers and quantities. Insurance is not included; arrange coverage separately.

Upon receipt, inspect for surface corrosion, bent orifices, or damaged threads. Test spray pattern using a nozzle tester if available. Retain packaging and documentation for claims. No warranty is offered, so performance must be verified before installation. For bulk orders, request a batch test report showing flow rate consistency across units.
