KDAS Piston Seal for Hydraulic Cylinder

Overview

KDAS Seal / Double Acting Piston Seal is designed for hydraulic cylinders requiring reliable sealing on both pressure and suction sides. Its structure includes an elastomeric profile seal ring, two backup rings, and two wear rings, providing sealing, anti-extrusion support, and guiding performance in one compact assembly.

The closed groove and integral piston design helps reduce piston length and machining costs while maintaining effective sealing performance. With excellent extrusion resistance, simple groove installation, and low overall product cost, KDAS seals are ideal for hydraulic equipment operating in demanding industrial and heavy machinery applications.
