Fit measure
Offering a wide range of options from 1.5L to 13L: 1.5L–3L for light trucks/mini buses, 5L–8L for medium-sized buses/trucks, and 10L–13L for heavy construction machinery/long-haul coaches. Tailored to diverse usage scenarios, it reduces refueling frequency and improves operational efficiency.

Quality
One-piece tank body made of high-density polyethylene (HDPE), withstanding extreme temperature differences from -40℃ to 80℃. Resistant to acid, alkali and gravel impact, compatible with all types of windshield washer fluid/antifreeze cleaning agents. Suitable for harsh operating environments such as rain, sand and salt spray.

Structure
Equipped with double-layer sealed screw cap and overflow-proof diversion port to prevent liquid leakage during vehicle jolting. Built-in anti-slosh baffle reduces noise caused by liquid sloshing and avoids water pump dry suction during sudden braking/climbing. Leak-proof design for key interfaces ensures long-term stable operation.

Design
OEM-grade mounting bracket enables bolt-on plug-and-play installation. Pre-reserved liquid level sensor interface supports real-time monitoring of remaining fluid volume. Adapted to engine compartment layouts of mainstream commercial vehicles/construction machinery, no extra modification required, reducing maintenance costs.
