LU Oil Spray Nozzle
The LU Oil Spray Nozzle is a precision engine-lubrication component designed to deliver a controlled jet of oil onto critical internal parts such as the piston underside and cylinder walls. This ensures optimal cooling, reduced friction, and enhanced lubrication in heavy-duty commercial diesel engines.
Manufactured from heat-resistant, high-strength alloy steel, the nozzle provides consistent spray patterns even under high oil pressure. Its calibrated orifice ensures accurate oil flow, contributing to improved piston cooling and extended engine component life. The durable construction ensures resistance to wear, clogging, and thermal stress.
The LU Oil Spray Nozzle plays a critical role in maintaining engine efficiency, reducing wear, and preventing overheating—especially in high-load and long-duration operations. It is an essential component for ensuring long-term reliability in commercial BS3/BS4/BS6 engines.
