Klein Tools 51006 3-in-1 Tube Bender — Bends 1/4, 5/16, and 3/8 OD Tubing to 180°

The Klein Tools 51006 3-in-1 Tubing Bender is designed to simplify common bending tasks with a single, purpose-built tool. It handles three popular outer diameter sizes (1/4, 5/16, and 3/8 inch), allowing you to switch between projects without swapping gadgets. The bending range reaches 180 degrees, enabling clean turns in confined spaces and reducing the need for rework on tight corners.

Three-in-one bending capability

• 1/4-Inch O.D. tubing
• 5/16-Inch O.D. tubing
• 3/8-Inch O.D. tubing

With these three sizes in one tool, you can tackle a variety of tubing layouts from a single device, saving time on site and keeping your workflow smooth. The 180-degree bending capacity supports full-turn bends when needed, while maintaining control over the bend angle for consistent results.

Materials, guidance, and comfort

• Suitable for soft copper, aluminum, and thin-wall steel or stainless tubing
• 180-degree bend capability for full turns where required
• High-visibility guide markings for accurate left-hand, right-hand, and offset bends
• Knurled handles deliver a secure grip even in challenging conditions
• Hooked design helps keep tubing secure during the bend process

These features work together to help you achieve precise bends with less guesswork. The bender’s materials compatibility covers common metals used in plumbing, HVAC, and light fabrication, while the visual guidance aids quick setup and repeatable results. The combination of a secure grip, stable tubing guidance, and a proven bending range supports consistent performance from job to job.

Design highlights for the jobsite

• Lightweight, portable form for easy transport between sites
• Compact profile fits into tight spaces where field work often occurs
• Designed for reliable performance under daily use by professionals

In addition to its practical bending capabilities, Klein Tools brings a long-standing heritage of American craftsmanship. The 51006 reflects a balance of durability, precision, and thoughtful features that respond to real-world workflows. While results depend on material type and setup, this tool offers a flexible option for field or workshop environments, enabling tradespeople to complete tubing bends with confidence without needing multiple dedicated tools.

If your projects frequently involve small-diameter tubing in copper, aluminum, or thin-wall steel, the 51006 can complement your toolkit by delivering consistent bends with a compact, portable design and clear guidance for faster setup and iteration.
