What is the standard bend radius for a 1" tube when using a portable hand bender?

The standard bend radius for a 1" tube when using a portable hand bender is 3 inches. This is a widely accepted practice in the industry and ensures that the pipe maintains its structural integrity while allowing for effective fluid flow. A bend radius that is too tight can cause kinks or reduce the diameter of the tube at the bend, leading to potential blockages or stress on the tube material. A 3-inch radius strikes a balance between minimizing the space required for the bend and ensuring a smooth transition for the fluid flowing through the tube. This consideration is essential for maintaining the efficiency and functionality of fluid lines in various applications.
