Frequently Asked Questions (FAQ)

What are double and single flares, and how do they vary from each other?

To understand this question, you first need to understand that flares come from a tubing contraption on the flaring kit. The tubing doesn’t have any modification for single flares and is most often just the tubing by itself. On the other hand, the double flare is where the tubing’s ending contains a double folding to make the double flare.

The two flaring techniques vary from each other in the nature of the plugs on the flaring tool. With the double flare, the plug contains flared ends on either side of the cylindrical jewelry. On the other hand, single flared plugs have a groove to hold the o-rings firmly in place.

Double flares are the more common flare on different vehicle types since single flares tend to tear faster when used on brake line systems. Double flares are usually stronger than single flares and are thus used on most brake systems.

What is the best flaring tool?

The Mastercool 72480 is our clear favorite. It has several adapters and an adapter holder that makes it easier to use. Furthermore, its stabilizing arms also make it easier to work with the die sets.

It also comes with a carrying case that makes it easier for you to store the tools and transport them from place to place. The option you decide to go with, however, rests with you. Remember to consider all the options we have outlined here before deciding.

Why do brake lines need double flares?

A brake system usually withstands severe pressure, which requires the system to be as strong as possible. Since single flares cannot withstand such pressure, it is preferable to use double flares for brake systems.

Single flares leak or crack much more easily than double flares, so they aren’t used that much. Double flares offer a stronger joint for the brake systems and easily deal with high pressure.

Logic dictates that if you are to use any flare in the brake system, it be as strong as possible. Brake systems are an absolutely vital part of any moving machine and, as such, need the strongest parts to ensure there are no accidental incidents.

What’s a Bubble flare, and how does it work?

Bubble flares are the other type of flares more commonly associated with vehicle brake systems. They function in much the same way as single and double flares, only that they differ in how they look and their make.

Bubble flares look like the top head of a screw head and aren’t interchangeable with any of the other flares for this reason. Double flare tools wouldn’t work for bubble flares due to these fundamental differences.

Which is the best flare to use on brake lines?

Although there are different types of flares that you can use on brake lines, a 45 degree double flare would offer the best results judging by the brake lines’ high-pressure system. A double flare has thicker lips which makes it the ideal candidate for vehicle brake lines.

Factors to Consider Before Buying the Best Flaring Tool:

What comes to your mind whenever you want to buy something you know will cost you a substantial amount of money? What do questions run through your mind? You might ask yourself whether the product is worth it or not.

When buying any product, it’s only natural to consider a few things. In that way, you can be sure to make the best possible decision when purchasing the tool you need.

Let’s look at some of the things you need to consider when buying flaring tools.

Flaring Tool Adapters

This should be one of the first things to consider when you are buying a flaring tool. That’s because you get varying numbers of adapters with each flaring tool. If you think you will need several adapters in your work, you will need to choose a flare tool with the ideal number of adapters.

That will therefore need you to consider the adapters on the flaring tool before buying.


The ideal flaring tool should be able to give you leak-free flares. Leaking flares will underscore the importance of the repair process itself, making it a non-issue that you spent a lot of time repairing your brake lines.

Durability of Material

The durability of the flare tool will be affected by the material used to make the tool. That’s why you need to consider the material of the tool before buying a flaring tool. Most of them are metal with a few plastic parts and might last you quite some time.

Stainless steel is a popular material as well since it doesn’t rust easily and is quite strong. The material you choose, however, will depend on your tastes and preferences.

The Cost of The Tool

Like any other product, flaring tools will also vary in price and features. Therefore, it will be up to you to consider the price and the features to know which one to go for.

Don’t focus too much on cheap flare tools since such tools might lack the necessary capacity to help you work on different brake line systems. The amount of work you will be doing will also determine whether you go for a highly-priced tool or not.


You will want to worry about efficiency in any tool and not just flaring tools. Certain aspects should guide you in selecting an efficient flaring tool. The number of adapters, ease of use, and ability to work in tight spaces should be top among those things.

An efficient flaring tool will give you better results and reduce the time you take on each task. That wouldn’t be a bad thing, would it?


By maneuverability, we mean the ability of the flare tool to be usable in tight spaces. When working on brake lines, you can avoid getting to a few tight spaces, especially when working with small cars. As such, you will need the flare tool to be maneuverable at best to give you an easier time.

That’s why some people usually prefer smaller flare tools that are easier to maneuver in tighter spaces.

Essential Tips to Remember When Flaring

  • When flaring, don’t rush. Take your time to ensure you come up with the right flare for the brake line system. Overlooking any details will lead to deficiencies in some lines, and you wouldn’t want that.
  • The simplicity of the toolset is often a quality that many people tend to ignore. A simple toolset won’t need too much work getting used to, and you can quickly get to grips with the controls. We wouldn’t say the same about elaborate tools.


Most people love to see themselves as these handy people that can fix most things. If you are one of those people, you need to know the best flaring tools. That is especially true if you are, you are going to be working on car brake lines.

The best flaring tools will ensure you not only work faster but also efficiently. There’s nothing quite as threatening as a brake line with low-quality flares. The high pressure in the brake line system might lead to accidents that you could have easily avoided.

We hope our review of the best ten helps you make a faster decision over which one to choose. Remember to consider all the things we have mentioned here before committing to buying any of the tools.

The ease of use should also prominently feature among the things to look for to avoid frustration when working on your car brake lines. If you consider all that, then it should be a problem choosing the best flaring tools.

All the best.
