Pull coiled tubing through these straighteners to make it smooth and level. They have acetal roller wheels that press your tubing into shape without marring the finish. Unlike pliers, which create kinks and bends that can restrict flow, these straighteners won't damage your tubing. To straighten tubing with different diameters, twist the adjustment knob to change the space between the wheels. Keep these straighteners steady by clamping them into your vise or mounting them to a work surface through holes on the base.

Flatten bumps, bends, and curves on coiled wire with these straighteners. They have roller wheels that apply consistent pressure along the wire for a smooth, straight result. Grooves in the wheels hold the wire in place as you manually move it through, so you don't need a wire feeder. To straighten wire with different diameters, twist the adjustment knob to change the spacing between wheels. The aluminum body resists corrosion from moisture. It's also nonmagnetic, so copper and other metal wire won't get stuck.

Kits include a handle and six interchangeable heads to fit a variety of fin spacings. Use them to clean as well as straighten fins on condensers and evaporators to keep cold air flowing.

Additional heads are sold separately.
