The S.U.R.&R. Handheld Tubing Straightener, No. TS224, is designed to straighten 3/16" and 1/4" tubing. It can be used on aluminum, copper-nickel, and steel lines. It straightens tubing with the flip of a convenient thumb-size selector, then slide the tubing through the straightener to eliminate curves or bends. It's ideal for creating long and consistently straight lines from bulk tubing coils. The TS224 can be used in a vise or on the vehicle thanks to its compact design that makes the tool easy to grip and control. The TS224 also works well with S.U.R.&R. UltraBEND flexible brake line tubing and Max Flex Alloy tubing coils or bundles.
