Import Diesel Nozzle 0 433 271 646 Dlla140s1252 — Buy in Bulk from Supplier in China

The Diesel Nozzle 0 433 271 646 DLLA140S1252 is a precision fuel injector component designed for use in Euro IV and V compliant medium-duty diesel engines. It features a single-hole pintle design with a 0.195 mm orifice, optimized for lower emissions and improved combustion efficiency. The nozzle body is forged from chromium-molybdenum steel and heat-treated for durability under cyclic high-pressure loads.

This nozzle follows the DLLA140S1252 standard, with a typical spray angle of 140 degrees and a seat angle of 60 degrees. The needle lift is approximately 0.12 mm, and the nozzle length is 76.8 mm. These dimensions are critical for compatibility with injector bodies from Cummins, Isuzu, and Yanmar engines. The internal surface finish is honed to Ra < 0.4 μm to reduce friction and carbon accumulation.

This nozzle is frequently sourced by diesel engine rebuilders, agricultural equipment suppliers, and marine repair centers in Latin America and the Middle East. It is typically sold in packs of 10 or 25 units, with each unit sealed in anti-static packaging. Buyers should confirm whether the nozzle includes a copper sealing washer, as this is not always included. Lead time and minimum order quantities are not listed and must be confirmed directly.
