Composite Seals Silrings

Discover the new range of composite seals

Silrings seals are of utmost importance for the sealing of hydraulic systems and cylinders, both in the rods and in the pistons, in static or dynamic applications. Their particular shape provide outstanding properties such as resistance to wear, friction and extrusion. Depending on the material of the energizing ring, Silrings are resistant to a wide range of chemical and thermal agents.
