Import Diesel Injector Nozzle Dlla145p129 — Buy in Bulk from Supplier in China

The Diesel Injector Nozzle DLLA145P129 is a precision-engineered component designed for use in medium- to high-pressure common rail diesel injection systems. It features a 1.45 mm orifice diameter and a 129 mm overall length, matching OEM specifications for applications in commercial vehicles and industrial diesel engines. The nozzle body is machined from hardened stainless steel with a hardened needle valve to resist erosion under sustained high-pressure fuel flow.

This nozzle is typically manufactured using AISI 4140 or equivalent alloy steel, with a surface finish of Ra 0.4 µm or better to ensure consistent fuel spray patterns. The spray pattern is designed for a 15-degree cone angle, standard for Euro V and Euro VI compliant injectors. While the listing does not specify certification, the dimensional tolerances align with ISO 15443-1:2015 for diesel injector nozzle geometry and performance testing. Typical wear life under normal operating conditions exceeds 150,000 km when used with clean diesel fuel meeting EN 590 standards.

This component is primarily purchased by fleet maintenance operators, diesel engine rebuilders, and agricultural equipment service centers across Southeast Asia and Eastern Europe. Buyers commonly order in batches of 10 to 50 units to support repair cycles. Packaging is in anti-corrosion blister packs with individual part labels. Trade terms are typically FOB Fuzhou Port, with lead times of 15 to 25 days after order confirmation. Buyers should confirm compatibility with their engine model before ordering.

Chen Chen Diesel Parts Plant is a manufacturer based in Fuzhou, Fujian Province, specializing in diesel fuel system components. The supplier is verified as a harbor-tier seller with a registered business address and industrial facility. The listing does not state years in operation, certifications, or export volume. There is no evidence of ISO or SGS certification in the provided data, and no client list or production capacity figures are disclosed.

The supplier responds to inquiries at a rate of 0.00% and has no recorded average response time, indicating limited or inactive customer communication. The product is listed as imported, suggesting the supplier may source or repackage components rather than manufacture them in-house. Buyers should treat this as a trading entity without confirmed production capability unless additional documentation is provided. The lack of response metrics and certification claims means verification of quality must occur through third-party inspection.
