RIDGID 36117 403 Instrument Bender - 3/16-inch Tube Bender for 180-Degree Bends

Overview

Meet the RIDGID 36117 403 Instrument Bender, engineered to shape annealed copper, steel, and stainless tubing with precision. Capable of bending up to 180 degrees, it helps you craft clean arcs in tight spaces while maintaining consistent results across projects. The tool’s robust construction and thoughtful details support both pro shops and on-site tasks, making complex bends feel attainable.

Ergonomics and Precision

Designed with user comfort in mind, this bender features offset cushion grip handles that reduce knuckle strain during extended sessions. A 90-degree start angle keeps your first bend aligned, while an oil-absorbing shoe minimizes resistance and helps you guide the tube with smoother control. Measurements are shown in both inches and millimeters for quick, on-the-spot reference.

Key Features

• Designed for annealed copper, steel, and stainless tubing with a wall thickness ≤ 0.06 inches (1.5 mm) and bends up to 180°
• 3/16-inch outside diameter tube capacity with a 5/8-inch bend radius
• Dual-scale measurements in inches and millimeters
• Offset cushion grip handles to improve comfort and reduce fatigue
• 90-degree start angle and an oil-absorbing shoe to ease bending effort

Real-World Use and Benefits

In practice, the instrument bender shines in workshops and field setups where copper, steel, or stainless tubing must be formed with reliable, repeatable curves. The combination of grip comfort, precise start alignment, and a forgiving shoe helps you achieve smoother bends without abrupt deviations. While not a guarantee of results, the design supports efficient workflows and consistent outcomes in common installation scenarios.
