The HHS® Tube, also known as Helical Hollow Strand, is best defined as a strand with an open center working channel.
While the HHS® tube has been proven to be useful in several medical-based applications, it is often utilized for transmitting torque or pushing forces because of a high resistance to kinks and its excellent whip free features. Furthermore, it possesses exceptional pushability, torquability and use tension. The HHS® tube can be manufactured in single, double and triple layers to provide varying flexibility and control.
To meet immediate HHS® tube requests, the company ships R&D orders of almost any HHS® tube in two weeks or less with the help of its VelocitySM HHS® tube rapid prototyping program.
We design HHS® tube to meet the specific needs of our customers. We can provide parametric drawings to assist in design review and quickly return requests for quotation. For standard HHS® tube capabilities, please reference the following variables:
- Inside Diameter*: .003” (0.0762 mm) to 0.120” (3.048 mm)
- Outside Diameter*: .006” (0.1524 mm) to 0.160” (4.064 mm)
- Filars*: 6-18
- Layers*: 1-3
- Lengths*: 1”-10' (25 mm – 3 m)
- Pitch Direction: left, right (alternating each layer)
*If you have a request that is outside of these specifications, please contact us.
