A2 dust ring function is to prevent dust, dirt, sand and metal shavings from entering. Through a special design to prevent scratches, protects the guiding parts and prolong the working life of the seal. These dust ring especially suitable for drying oil-free pneumatic equipment. Before you install must be pre-lubricated. There is interference diameter can guarantee seal tightly into the slot to prevent foreign particle and moisture intrusion.

   A2 dust ring to provide a hermetic cavity cylinder, without screws and brackets. Unnecessarily tight tolerances, and no metal inserts to prevent corrosion phenomena like metal skeleton dust ring may occur. Trench and without tight tolerances.
