Import Diesel Nozzle 5643837 Dn4sdnp133 — Buy in Bulk from Supplier in China

The Diesel Nozzle 5643837 Dn4sdnp133 is a diesel fuel injector nozzle designed for use in light to medium-duty diesel engines, particularly those found in industrial generators and commercial vans. It features a 4-hole spray pattern with a 0.20mm orifice diameter and a conical seat for secure mounting. The nozzle body is machined from high-strength alloy steel with a surface chrome finish to resist corrosion from low-sulfur diesel fuels.

This nozzle is built to industry-standard tolerances for flow consistency and spray angle. Typical values for this class include a 140-degree spray cone and a flow rate of 210 to 230 mm³ per stroke at 1500 bar. The internal channels are polished to reduce friction and prevent carbon buildup. The tip is hardened to HRC 58-62, matching the durability requirements of high-pressure common rail systems.

Common buyers include fleet maintenance operators, generator repair shops, and agricultural equipment service centres. The nozzle is supplied in protective plastic sleeves with batch identification labels. Packaging is in standard cartons with anti-rust paper. Bulk orders are accepted with lead times of 18 to 30 days. Trade terms are FOB Fuzhou Port, with payment via T/T or L/C.
