Fuel Injector Nozzle 6801026

The Fuel Injector Nozzle 6801026 is a direct replacement component designed for medium- to heavy-duty diesel engines, commonly used in commercial trucks and industrial generators. It features a 5-hole spray pattern with a nominal orifice diameter of 0.18 mm, manufactured from hardened tool steel to resist cavitation erosion. The nozzle body is precision-machined to fit injector pumps compliant with Bosch and Denso mechanical injection standards. This part is identified by the OEM code JB6801026 and is compatible with specific Cummins, Isuzu, and Mitsubishi diesel models.

The nozzle is made from high-carbon chromium steel, heat-treated to achieve a hardness of 58-62 HRC, which is standard for durable fuel injection components. The tip is laser-welded to the body to ensure structural integrity under high-pressure cycles. While the supplier does not specify exact tolerance ranges, typical industry standards for this nozzle type allow a ±0.002 mm variation in orifice size and a maximum tip runout of 0.005 mm. Surface finish on the sealing face meets ISO 1302 Ra 0.4 µm, critical for preventing fuel leakage under 2000 bar operating pressure.

This nozzle is primarily purchased by aftermarket distributors, fleet maintenance providers, and engine rebuilders serving Asian and African markets. It is typically sold in batches of 10 or more units, with packaging in anti-corrosion paper and sealed plastic sleeves. Lead time for bulk orders is confirmed upon request. Buyers should verify compatibility with their engine model using the JB prefix code, as similar part numbers may have different spray angles or flow rates. Trade terms are negotiable but commonly FOB Fuzhou.

Chen Chen Diesel Parts Plant is a manufacturer based in Fuzhou, Fujian Province, specialising in diesel fuel injection components including nozzles, plungers, and delivery valves. The supplier is listed as imported and verified by harbor-level trust signals, indicating active export activity. The profile does not state years in operation, employee count, or revenue. It does confirm direct production of parts under the JB prefix codes and references export experience across multiple countries.

There is no mention of certifications such as ISO 9001, IATF 16949, or OEM approvals. The supplier does not list specific client brands or test reports. Response rate and average reply time are not available, suggesting limited buyer communication infrastructure. Buyers should treat this as a factory-direct source with no third-party quality assurance claims. Verification of part compatibility and performance must be conducted independently before bulk purchase.
