Triangular faceted four-sided face design: the large pipe is closer to the socket handle, which is more labor-saving. The length of each rib is scientifically calculated to ensure the depth of insertion of the butt pipe, while the depth is more flexible.
Scope of application: 4-22 copper tube
Material: zinc-iron alloy
Double-head design: greatly reduces the size of the entire tool. It is more suitable for small spaces, but it is easy to operate and has great flexibility.
Built-in return spring: There is no need to pull back the handle when expanding the tube. The built-in powerful tube will automatically reset, and it can be easily expanded by simply pressing the handle.
