Brake Line Flaring Like a Pro

A good flare is an essential part of your brake, transmission cooler or fuel lines, as it ensures they will connect solidly without any leaks. This brake line flare tool will pay for itself with the first project, and it'll give you peace of mind knowing that your brake flares are of OEM-precision quality and safety. You don't want to skimp on the brake system of your project or street vehicle! With the right tool, you'll never have to worry about your lines coming up short.

37 Degree Flare Die Set

Create 37-degree flares used in many custom, hydraulic and military applications where AN- or JIC-type fittings are used. It's a "must have" accessory for custom plumbing and line-fitting on your street rod or hot rod.

Make Any Type of Flare

Why search for a separate bubble, single and double flaring tool when you can get all three in the same kit? This brake flaring tool mounts in your vise to help you easily form 45-degree flares in OEM steel, stainless steel, and soft metal tubing. It mounts directly to your benchtop vise and be stored in a cabinet or toolbox when not in use. DIY enthusiasts can use our brake line flare tool on 3/16-inch, ¼-inch, 5/16-inch, 3/8-inch and 4.75mm-diameter lines using the included split dies. This means it will handle all your plumbing jobs from brake lines to transmission cooler lines and fuel lines.

Easy to use Turret-Style Design

The "turret-style" design allows you to make precision flares in minimal time. All the brake-flaring forming dies you need are mounted right on the turret, so there's no fumbling for small parts, no worry about missing dies. All you have to do is rotate the die head to the line size you need to flare, add the die and then use the lever handle to bend the line. A T-handle screw clamp securely holds your line in place during forming.

Each Tool Manufactured with the Highest Quality

Every Eastwood Pro Flaring Tool is inspected and tested before it's shipped to you! The factory does a test operation using 3/16-inch brake line on each tool. When you receive your flaring tool you will find a piece of brake line left in the installed block showing this has been done. This ensures that every tool manufactured meets Eastwood's high quality standards. Compare our flaring tool to high-dollar European or U.S. models and see for yourself - you can't beat the high-quality results you'll get with this brake tubing flare kit. It's a professional-grade tool at a do-it-yourself price.

Will this tool perform 10mm bubble flares?  I bought this tool and the turret reads 3/8”/10mm but I have no die that reads 10mm.

Asked by: Adam2
You would use the 3/8" inch die for this operation.

To make a 37 degree single flare do I use operation “0” then go to operation “2”? And for a double 37 degree is operation “0” then “1” and “2”? 

Asked by: Rob85
Single flare is achieved by running operation 0 and operation 1 before you tighten the dies down to hold the line. This pushed the line the proper depth inside the die blocks so that when you run operation 2 you create the perfect single flare.

Do you have a case the will hold both sets of dies and tool

Asked by: Mercuryboy
Unfortunately at this point the case only holds the first set and the 37 degree set comes in their own storage box. You could use the stock case to hold your favorite dies as you'll undoubtedly have a set of favorites you use commonly.
