Product Description

Dust seals are generally used in conjunction with round rubber rings in some mechanical equipment and hydraulic piston systems. They are installed in the connection parts of the machinery to prevent external dust and dirt from entering the equipment. Especially in large excavators and bulldozers working in harsh environments, a large number of dust seals are required in the four-wheel area and hydraulic system to prevent mud and sand from intrusion and protect the machinery.
