Injection Nozzle – Steel Finish with Oil Coating (NK) for Zetor – Product Description

The Injection Nozzle – NK (Steel Finish with Oil Coating) is a precision-engineered diesel fuel injection component designed for Zetor tractor engines. It atomizes diesel fuel into a fine, high-pressure spray inside the combustion chamber, ensuring efficient combustion, improved engine performance, lower fuel consumption, and reduced exhaust emissions.

Manufactured from premium-grade hardened alloy steel, the nozzle features a natural steel finish with a protective anti-corrosion oil coating. Unlike black oxide-coated nozzles, this version retains its original steel appearance while remaining protected during storage and transportation. The nozzle is precision-ground and tested to OEM standards to ensure accurate fuel delivery and long service life.
