INOFLEX metal hose is made from stainless steel tubing. Through a patented system and special machines it is possible to obtain convolutions. Such convolutions are complete rings in themselves, without circumferential welding and parallel to each other. Employing very thin gauges determines the main characteristic: flexibility. The flexibility changes in functions of the convolution pitch. To this regards, two types are foreseen : Type XS-25 close pitch (high flexibility) and Type XN-25 normal pitch (normal flexibility).
