Editor’s Recommendation: Top Five Bubble Flare Tool
What To Look For Before Buying?
Before buying your very first bubble flare tool, you must restrain your excitement and allow yourself some time to consider certain factors. Otherwise, you’d end up buying one that just cannot live up to your expectations.
- Brake System
The very first thing you have to consider is the brake system and the brake line flaring tool used in the vehicle. That’s because bubble flare tools aren’t compatible with all systems. This knowledge will allow you to choose the appropriate tool.
Always make sure that your flaring tool doesn’t have any leakages. The use of high-quality materials in its construction and solid fittings reduce the chance of leaking.
Your flaring tool must be efficient enough to meet your requirements. It must have all the important components. Check whether it can make decent flaring without harming the brake lines or not before buying.
It’s pretty important to make sure your flaring tool is applicable to the brake system of your car. Some require a double flare, and some require a bubble. So, this comes down to compatibility as you won’t be able to apply it unless your vehicle and the flaring tool of your choice are compatible with each other.
You must consider your budget and go for the one that suits it the most. Expensive ones usually provide more features and quality. But if you can’t afford them, make sure the one you get at least has decent quality and the must-have features.
- Quality of Materials
Some tools are poorly made, which are bound to be ruined in a very short time. You don’t want yours to break soon or bring harm to your braking system. So, consider the materials that were used in the construction of the tool. You’d be wise to choose the ones that are designed to last.

What Is the Difference Between Double Flare and Bubble Flare?
Flaring is basically a process of forming a leak-proof connection by placing a flare to the end of the brake line. Double flare and bubble flare are the most common form of brake line flares. Although they may seem similar, there are certain characteristics that set them apart.
The double flare is most commonly found on older vehicles. It is made by grabbing the single flare and folding its lip over, which results in a double layer of flares. It uses the standard SAE thread fitting. The double flare is far stronger and more durable than single flares.
Bubble flares started to gain popularity in the ‘80s. They are usually found in the newer model of vehicles. The name comes from the fact that the end of the line is bubbled up. They use metric fittings, unlike the double flares. These flares are also extremely capable of providing leak-proof connections.
