Flaring Tool – What Is It Used For?

When dealing with chemicals, pipes can often become prone to corrosion and rotting. For eg: in the automotive industry, bad lines are often caused when using products such as coolants, brake fluid and various other corrosive liquids. A flare tool will enable you to make the appropriate bends to achieve a seamless connection between two adjoining components without the need for costly repairs.

Depending on what you need it for, a pipe-flaring tool can also be manufactured in different sizes to suit a specific task such as creating larger openings, implementing centering yokes or adding other complementary components such as flaring adaptors for more complex tasks. Aluminium, steel and brass tubes are also compatible materials that can be used for flaring. 

Pipe Flaring - How Many Flaring Tools Are There?

Typically, the kind of flare tool used depends on what you need it for. The four most common types include: manual, hydraulic, single flare and double flare varieties.

Long Engineering has been providing specialised pipe flaring tools to various industries for over 35 years. Based in Sydney, we are proud to be recognised for our quality workmanship, precision 4-axis CNC turning and milling solutions.

Flaring Tools – Common Questions Answered

What does a flaring tool actually do?

A flaring tool is designed to widen the end of a metal tube, creating a cone-shaped flare. This shape allows the tubing to fit tightly against a flare nut or fitting, forming a strong, leak-proof seal. It’s commonly used with copper, aluminium, and brass tubing in plumbing, refrigeration, HVAC, and automotive systems.

How do I use one correctly?

Using a flaring tool isn’t complicated once you get the hang of it:

1. Cut and clean the tube – Trim it to the required length and smooth out any burrs or sharp edges.

2. Secure the tubing – Clamp it into the flaring block so it sits firmly without being crushed.

3. Lubricate – A small dab of oil or lubricant on the cone helps prevent friction.

4. Create the flare – Slowly press the cone into the tube until a neat flare forms.

5. Check your work – The finished edge should be smooth, even, and free from cracks.

Can I flare plastic pipes?

No – flaring tools are only meant for metal tubing. Plastic pipes can warp or split under pressure from the flaring process. Instead, use fittings or connectors designed specifically for plastic materials.

What kinds of flares can I make?

There are a few types, each suited to different jobs:

• Single flare: A basic conical flare for low-pressure use.

• Double flare: Reinforced with a second fold, ideal for brake lines and high-pressure systems.

• Bubble flare: A rounded flare often used in fuel or gas applications.

Should copper tubing be softened first?

Sometimes. If the copper feels too rigid or thick, heating it briefly (annealing) can make it easier to form a clean, even flare. For softer copper, it’s usually not necessary.

How do I look after my flaring tool?

A little care goes a long way:

• Wipe it clean after every use.

• Keep the moving parts lightly oiled to stop rust.

• Check the cone and clamp for any signs of wear before each job.

Can the same tool handle different pipe sizes?

Yes. Most flaring kits include multiple dies or adaptors for different tubing diameters—typically from 3/16” to 5/8”. Always match the die size to your tubing for an accurate, even flare.

Are flared joints stronger than threaded ones?

Generally, yes. Flared connections form a tight mechanical seal that resists leaks and high pressure, without needing extra sealant or tape.

Is a yoke essential?

A yoke provides stability while you’re forming the flare. Some compact tools skip it, but if you’re after precise, consistent results—especially for professional or automotive work—a yoke is highly recommended.

Are flaring tools suitable for beginners?

Absolutely. With a bit of patience and practice, anyone can master it. Follow the instructions closely, use the right size fittings, and take your time forming each flare—you’ll get professional-quality results in no time.
