Kastaş piston seals provide reliable fluid sealing in both dynamic and static conditions. They are highly resistant to extrusion, withstand sudden pressure changes, and offer a long service life.
Operating parameters depend on the specific model material and geometry
Working pressure up to 450 bar for profiles designed for heavy-duty conditions.
Temperature range from -200°C to +260°C for specialized PTFE materials, and from -50°C to +135°C for polyurethane (PU) and nitrile (NBR) compounds.

01These components are widely used in mobile hydraulics, the mining industry, and various industrial equipment.
02Main design and operational advantages
03Maximum leakage protection: a special multi-lip geometry fits tightly against the cylinder wall, fully blocking fluid bypass even during long standstill periods.
04Resistance to high pressure and shocks: models designed for heavy-duty conditions are equipped with fiberglass-reinforced thermoplastics or backup rings. They withstand instantaneous pressure spikes up to 400 bar.
05Low friction and smooth movement: the combination of PTFE, TPU, and NBR materials reduces initial friction and eliminates stick-slip movement at low speeds.
06High wear resistance: fabric-reinforced elastomers and premium polyurethane resist abrasive particles, contaminated environments, and irregular cylinder surfaces.
07Compact and easy installation: multi-component sets eliminate the need to machine additional guide rings. They are compatible with ISO 7425/1, simplifying replacement.
