Import Diesel Injector Nozzle Dsla150p502 — Buy in Bulk from Supplier in China

The Diesel Injector Nozzle DSLA150P502 is a precision-engineered component designed for direct injection diesel engines, commonly used in commercial vehicles and industrial machinery. It features a 5-hole spray pattern with a nominal orifice diameter of 0.18 mm, matching OEM specifications for fuel atomization efficiency. The nozzle body is machined from high-strength alloy steel with a hardened tip to resist erosion under high-pressure conditions of up to 2200 bar.

This nozzle is typically constructed from AISI 4140 steel with a surface hardness of 58-62 HRC and a chrome-plated exterior for corrosion resistance. The internal flow channels are precision honed to a tolerance of ±0.002 mm to ensure consistent fuel delivery. In standard industry practice, such nozzles are tested for leakage at 150 bar and calibrated for spray cone angles between 140 and 160 degrees. These characteristics align with common aftermarket replacements for Bosch and Denso systems.

Buyers in the heavy transport, agricultural machinery, and marine diesel sectors use this nozzle for engine rebuilds and maintenance. It is supplied in sealed anti-static packaging with individual part-number labels. Bulk orders are typically packed in cartons of 50 units, with custom packaging available on request. Lead time for stock items is 7 to 14 days, and trade terms are negotiable but commonly FOB Fuzhou or CIF destination port.
