DAS seals are heavy-duty, double-acting piston sealing systems designed for demanding hydraulic applications where reliable sealing is required in both directions of movement. They are commonly used in hydraulic cylinders operating under high pressure, particularly in mobile and industrial hydraulic equipment.
The DAS seal design consists of a primary elastomer sealing element supported by rigid backing components, ensuring controlled deformation, excellent extrusion resistance, and stable sealing performance under dynamic conditions. This construction allows the seal to maintain consistent contact pressure while minimizing friction and wear over long service intervals.
