Materials and Manufacturing:

The valve body is precision-machined from high-strength alloy steel, and the needle valve assembly is precision-matched and ground. It withstands high temperatures and pressures, resists corrosion from low-quality diesel fuel, and is designed to withstand the harsh operating conditions of small construction machinery on dusty job sites with frequent start-stop cycles.

Repair and Replacement:

Replaces original injectors with poor atomization or those that are worn and stuck, resolving issues such as difficult cold starts, idling vibrations, black exhaust smoke, high fuel consumption, and insufficient power. These are essential maintenance and repair parts for small construction machinery repair shops.

Stringent Quality Control:

The product undergoes comprehensive bench testing for injection pressure, atomization performance, and sealing integrity, with performance meeting original equipment manufacturer (OEM) standards. We support both individual purchases and bulk orders from repair shops.

Warranty: 6 months
