Add more versatility to your 25304 Professional Brake Tubing Flaring Tool with the Eastwood 37 Degree Flare Die Set. While the 25304 is designed to produce 45-degree flares, this 37-degree flare tool allows you to create another fitting size. This flare set is a great fit for many custom, hydraulic and military applications where AN- or JIC-type fittings are more commonly used. Whether you use it for custom plumbing on a street rod, line-fitting on a hot rod or another automotive restoration project, you'll find that it produces incredibly precise results quickly and easily. Simply use the included four die blocks to convert your 25304 so it can create 37-degree flare fittings. This flare set also comes with seven punch sizes (turret-style) as well as detailed instructions for using the 37-degree flaring tool on 3/16", 1/4", 5/16" and 3/8" tubing.
