Conical Spring Seals are single-spring, unbalanced sealing units equipped with an auxiliary O-ring to provide secondary sealing support.

Torque is transmitted through the single conical coil spring, making these seals dependent on the direction of shaft rotation, which is determined when viewed from the drive end.

These unbalanced configurations utilize taper springs in different sizes and styles, allowing them to adapt effectively to a wide range of applications and process needs.
