With a broad range of spiral reinforcing materials available including high strength monofilament polymers and flat and round stainless steel alloys, and outer diameter dimensions from < 2 Fr (0.66mm) to 27 Fr (9.0mm) and inner diameter (lumen size) of 0.003 inch (0.075mm) we can design a tube that achieves your application requirements. We also have the capabilities to adjust the density of the spiral over one length resulting in your spiral reinforced tubing having different levels of flexibility.
