Antstone 3-in-1 Tube Bender for 1/4", 3/8", 1/2" O.D. Tubing – Lightweight Aluminum HVAC Tool

Meet the Antstone 3-in-1 Tube Bender

Designed for soft copper and aluminum tubes, this compact tool brings three common tube sizes under one lightweight body. With an outer diameter range of 1/4", 3/8" and 1/2", it covers most standard HVAC and refrigeration tasks without swapping tools.

The bending radii are listed as 0.82", 1.14", and 1.43" (21 mm, 29 mm, 36.5 mm) for smooth, controlled curves that help minimize kinks and flattening along the bend line. The 0 to 180 degree range lets you dial in gentle curves or sharper turns as needed.

Industrial-grade yet portable, the Antstone bender is built to travel between job sites. The aluminum alloy body resists corrosion and stays cool to touch during extended sessions, while the compact footprint fits into tool bags or pouches without bulk.

The 3-in-1 design is a notable convenience: you can switch tube sizes on the same axis, reducing downtime and tool clutter. The soft rubber handle cushions the grip, helping reduce fatigue when performing several bends in a row.

Key design highlights include an aluminum alloy body and a three-size capability, teamed with a lightweight frame that supports precise, repeatable bends in tight spaces. This makes it a practical option for technicians and DIY enthusiasts alike.

What you can accomplish with this tool

• Prepare soft copper and aluminum tubing for HVAC loops, refrigeration lines, or automotive repairs.
• Achieve consistent bend angles across three tube sizes with a single tool.
• Carry an efficient, portable bending solution to field service jobs or shop setups.

Usage tips and care

• Ensure the tube wall thickness stays within 0.027" to 0.059" (0.7 mm to 1.5 mm) to prevent damage.
• Apply steady, even pressure and support the tube during the bend for best results.
• Keep the tool clean and dry after use to preserve the alloy finish and grip.

While this tool supports a wide range of common tasks, results depend on material quality and application. Consider it a versatile helper for routine bends in HVAC, refrigeration, or mechanical systems rather than a guaranteed outcome.
