Javac Ratchet Tube Bender Kit (JRTB100)
Stop wrestling with awkward lever benders and wasting your profit margins on expensive brazed elbows. The Javac JRTB100 Ratchet Tube Bender Kit is a premium, crossbow-style tool designed to create perfect, kink-free bends up to 90° with minimal physical effort. Engineered to Javac's high-quality standards, this comprehensive kit includes everything you need to cut, deburr, and precisely shape soft copper and aluminium tubing on the job site.
Key Features & Trade Benefits
- Effortless Crossbow Action: The ratcheting trigger mechanism gives you massive mechanical advantage, allowing you to easily bend thick pipes with one hand without straining your wrists or knuckles.
- Perfect 90° Bends: Consistently creates smooth, professional 90-degree bends without kinking or flattening the tube, ensuring unrestricted refrigerant flow.
- 7 Quick-Change Dies: Comes fully equipped to handle every common HVAC/R pipe size: 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", and 7/8".
- Reverse Bending Capability: Includes specialty reversing arms, allowing you to push a bend away from the tool body—an absolute lifesaver when working in cramped corners or ceiling cavities.
- All-In-One Solution: We've included a heavy-duty tube cutter and a deburring tool right in the box, giving you a complete pipe preparation station in one neat carry case.
Tradie Pro Tip for Tube Bending:Every time you use a bender to create a 90° turn instead of brazing on a copper elbow, you eliminate two potential leak points and save yourself 10 minutes of hot work. Always ensure you thoroughly deburr the inside of your cut pipe before inserting it into the bender to prevent metal shavings from traveling into your compressor.

Frequently Asked Questions (FAQ)
Why is a crossbow bender better than a standard lever bender?
Standard lever benders require two hands and a lot of upper-body leverage to pull the pipe around the die, which can be nearly impossible in tight spaces. A crossbow bender uses a ratcheting trigger mechanism. You simply squeeze the handle repeatedly with one hand, and the tool does all the heavy lifting for you, ensuring a perfect, effortless curve every time.
Can I bend hard-drawn copper with this kit?
No. Like all manual tube benders, attempting to bend hard-drawn copper directly will result in the pipe snapping or flattening. If you need to bend hard-drawn pipe, you must first anneal (heat) the specific section of the pipe to a dull cherry red with an oxy-torch and let it cool to soften the metal before using the bender.
What are the reversing arms used for?
Standard operation pulls the ends of the pipe toward the handle of the tool. However, if you are pressed up against a wall or working inside a condensing unit, you might not have room for the pipe to fold backward. The reversing arms flip the bending direction, pushing the bend away from the tool, giving you unmatched versatility in tight quarters.
