for stainless tubing－I - ｆｉｔ
１. Features
Two parts: body and nut. (The ferrule is integrated with the nut.)※ Some parts have three components. For details, please refer to the specifications below.

Construction problems such as dropping/losing ferrules and wrong-way insertion are eliminated to zero.
Two types are available: rotation control type and Nut Full Tightening type (optional).
3/4 and 1 inch sizes reduce tightening torque by about 30% and are ideal for weldless pipe installation.
