Piston seal K16 100x86x22,5

The K16 compact piston seal set by Kastas is a three-component, double-acting seal designed for use in hydraulic power systems. This design is used in equipment operating at high working pressure and in standard industrial, construction and agricultural machinery where transverse loads and pressure spikes occur. Seal profile design The K16 profile consists of three integrated elements that perform both the sealing and the guiding function: Central sealing element: Made of a special nitrile rubber (NBR) compound vulcanised to a technical fabric structure (fabric-rubber). The fabric layer reduces dynamic friction, counteracts extrusion of the material into the installation gap and increases resistance to abrasive wear under high pressure. Guide and support rings: Two polyacetal (POM) rings located symmetrically on both sides of the sealing element. They absorb the radial (transverse) forces acting on the piston, stabilise the seal in the groove, prevent extrusion and eliminate direct metal-to-metal contact between the piston and the cylinder bore. The lip design of the K16 profile allows optimal retention of the lubricating film on the sliding surfaces. The seal is compatible with mineral hydraulic oils (DIN 51524) and water-oil emulsions of types HFA, HFB and HFC. The set is intended for installation in closed grooves (for diameters above 50 mm) or open grooves.
