Function & benefits
This bender delivers smooth, precise bends up to 180° while reducing effort and avoiding crossed handles — thanks to Imperial’s patented Roto-Lok™ quick-action handle. When both handles begin to meet, Roto-Lok™ re-indexes the two-stage handle mid-bend, so you keep control and finish the pull cleanly. Fair dinkum time-saver on cramped installs.
- Bends 3/16″, 1/4″, 5/16″ and 3/8″ O.D. tubing accurately
- Reduced effort with better control during bending
- Ideal for fabrication and repair work requiring precision
Where it can be used
Perfect for HVAC/R, plumbing, and automotive pros who need tight-radius bends in copper, aluminium, and thin-wall steel tubing. No worries if space is tight — the 470-FH is built for it.
- Great for working in confined or awkward spaces
- Useful in both workshop and on-site jobs
- Makes left-hand, right-hand, and offset bends easy
Key features
- Patented Roto-Lok™ indexing lever for two-stage handle movement and no crossing of handles
- Optimum bending radius for each tubing size for cleaner flow and fewer flat spots
- Calibrated markings (0–180°) for accurate, repeatable results
- Cushion grips for comfort and stability
- Lightweight die-cast aluminium construction
- Compact design fits easily in tight spaces
Why this tool matters on real jobs
On a hot Sydney roof swap, you’re threading new lines behind a ledger and there’s just enough room for a 180. With the 470-FH, you index the handle mid-pull, clear the frame, and land a neat bend first go. Charge, pressure test, and you’re off site before peak hour. She’ll be right.

Pro tip
For clean 180s in soft copper, de-burr and square-cut the end first, then use the calibration marks to set your start point. If you’re working in humid Brisbane plant rooms, chalk the tube lightly so you can see your witness marks while you pull the bend.
