K-grooved rings

K-grooved rings are compact, double-acting powerhouses for demanding piston sealing applications.

K-grooved rings are a special type of seal with a highly compact geometry. They have a square or rectangular cross-sectional profile. Unlike standard seals, the sealing legs are shorter and more robust. This compact design prevents tilting in the installation space and allows for pressure application on both sides within a single sealing element. They are designed for specific piston guides to guarantee optimal sealing performance with minimal wear, even with short strokes and high frequencies.
