Product Description
They are single conical springs that have an unbalanced seal, and an O-ring provides secondary sealing. Here, the spring seals are dependent on the directions of the rotation, which are visible from the drive end of the shaft. The torque transmission, too, is done by the single coil. Right-handed springs and left-handed springs are made for clockwise and anticlockwise rotating shafts, respectively. The seal is specially designed for extremely corrosive chemicals, including concentrated acids, salts, strong oxidizing and reducing agents, and chemically active organics.
