HHS® tube, or Helical Hollow Strand, is best described as a strand with an open center working channel. While HHS® tube has proven to be useful in many applications, it is most often utilized to transmit torque or pushing forces due to its exceptional whip free characteristics and a high resistance to kinks. HHS® tube can be manufactured in single, double, and triple layers in order to provide varying flexibility and control.
