The SW Stahl wrench features sizes of 12 mm and 13 mm, with the following dimensions: width 25 mm, height 11 mm, and a length of 168 mm. This open-ended wrench with a hexagonal profile is specifically designed for working on brake lines. Brake lines should be regularly checked, as metal lines are often susceptible to corrosion. For many connections on the brake system, it is advisable not to substitute the SW Stahl brake line wrench with another type of wrench, such as an adjustable wrench. A brake line wrench is best suited for tasks like loosening connections at the master cylinder, brake calipers, or wheel brake cylinders due to its unique shape. Using other wrenches poses a risk of damaging the screws. The brake line wrench adapts better to the connection due to its special hexagonal profile, making it more gentle on the material. Our line wrench is made from high-quality chrome-vanadium steel. It has a special alloy, where the addition of chromium and vanadium results in a composition that is particularly distinguished by its hardness and strength compared to other steels.
