KDAS Combination Seal is a multifunctional combination seal The function of guiding and sealing is realized by the seal itself in a small space Compact, simple, short length Integral piston mounting. The combination seal consists of a polyurethane sealing ring, two support rings and two guide rings, with a polyurethane sealing element in the center that actually seals; and a retaining ring and a wear ring on each side. The retaining ring prevents the seal from being pushed out into the gap; the seal in the center is a toothed seal, which provides a good seal at rest and in motion. The wear ring acts as a guide for the piston in the cylinder and withstands radial forces.
