Internal spring bending guide for pipes

Spring pipe benders are designed for manual bending of multilayer (metal-polymer) pipes
without kinking, with a bending radius of at least three times the outer diameter of the pipe.
The internal spring bender is equipped with loops for attaching a wire or cord, which allows the
tool to be easily extracted from the pipe after bending.Its diameter is slightly smaller at the
ends, making insertion and removal from the pipe easier.
