Isn’t it interesting how one metal can bend and change the entire shape of another with the help of some pressure? That’s what an HVAC flaring tool does.

Best HVAC Flaring Tool

It expands the pipe end so you can connect it to another end user in cooling and heating systems.

Its cone is the main shape-shifter. As you rotate it towards the pipe, the process spreads the end and gives it a conical shape.

You don’t need a special environment. Just having a room temperature will do.

Several kits may brag about how great they are but a few of them have managed to keep their words. They ensure durability, versatility, ease of use, efficiency, and accurate result.

What To Look Before Buying an HVAC Flaring Tool?

What Features To Look Before Buying Best Hvac Flaring Tool

1. Solid Construction

Almost all the flaring tools are made of hardened stainless steel with low-key alloy. The combo makes the construction much stronger than the single steel.

Such material is treated with high temperatures of up to 1,500°F. And consequently, it helps increase ductility as well as strength of the material.

The cone is plated with a chrome finish that works to make the rotation smoother. It leaves the surface of the cone as well as the workpiece free of damage.

So, your flaring tool should have these materials if you want it to work efficiently.
If you have to use the tool frequently- make sure it’s not heavier than 4 pounds. Otherwise, you may end up with pain in your hands and wrists.

2. Secure Setup And Ease Of Use

When it comes to the setup, there are 2 types to do the job. The easiest one is the single feed screw and handles system just like this tool. It’s ideal for both beginners and professionals.

You just need to slide the yoke to the desired hole size and let it lock into the dimple itself. Tighten the wing nuts and use the top handle to rotate the cone and make flares.

Not only it’s easy, but also reduces the chances of damaging the tube surface. The second type has a clamp screw at one side of the yoke. For instance, this tool.

It requires you to attach the yoke to the bar and fix the tube tight by turning the side screw. This helps make the entire assembly more secure. However, if you aren’t careful enough, you can damage the tube surface.

Hence, it’s typically perfect for pros because they know how to set up the tool safely. Although it has an extra step, using the tool is easy. After tightening the side screw, simply turn the top ratchet and expand the tube end.

3. Size Range

Pick an HVAC flaring tool depending on the tubing size you have mostly. If you have multiple sizes, opt for a model with a broader range of holed presets.

For example, this tool by Thorstone has 3 holes in one bar and 6 in another. You can fit pipes measuring from 1/8 to 3/4 inches in diameter.

In case you deal with tubing of a certain size, then choose the tool accordingly. The majority of the products have holes for pipes that are 3/16 to 5/8 inches.

4. Flaring Of Different Materials

Your HVAC flaring tool should at least shape softer materials. Two of them include aluminum and ductile copper. Because the tubes are made of such materials, the tool has to make sure it flares such tubing with ease. One suitable model is this one.

Some tools work great with both- soft and hard materials. Even if the pipes are thick, they expand the end efficiently. For instance, this tool can smoothly flare aluminum, plastic, as well as copper, brass, and steel- be it hard or soft.

5. Kit Components

Many flaring tools include other components in the package. One of the versatile items is the swage adaptor. Some kit features a few heads that can be attached to the yoke so you can change the pipe end to different cylindrical shapes.

Another handy item is the cutter. This helps you cut the pipe and remove the defective part. It also makes the edge of the pipe neat and even for smooth flaring.

Some kits also have deburring tools. Such an item removes burrs or sharp edges from the tubing. This also makes the pipe ready for a nice shape.

However, getting these items depends on your necessity and preference.

How To Flare Copper Pipe For Air Conditioning?

How To Flare Copper Pipe

Step 1- Prep The Copper Pipe

Make sure to remove the defective part from the copper pipe. Use a tube cutter and cut it well. This will make the edges clean and help remove burrs.

Even if you notice burrs, use a deburring tool to remove them and other debris. If you don’t have such a tool, use an abrasive cloth, pipe reamer, or sharp knife instead.

Step 2- Add The Flare Nut

Slide the nut onto the copper pipe. This helps secure the tapered end of the flared tubes. Plus, it produces a pressure-resistant and leak-free seal while making a connection between both flared ends.

Step 3- Insert The Pipe Into The Tool

Choose the hole that matches the diameter of the pipe that you will flare. Set it over the pipe end in the bar. The end should extend about 1/8 to 1/16 of an inch from the bar. However, it’s better to take an expert’s help if you aren’t sure.

Next, tighten the wing nuts and fix the copper pipe in the tool. Some need the side screw to be tightened instead of wing nuts for the same. Also, don’t over-tighten as it can cause damage to the pipe.

Apply a small drop of oil to the cone so you can smoothen the process.

Step 4- Flaring It

Now, center the cone right over the copper pipe and turn the top handle to bring both in contact with one another. Keep rotating the handle until the end is completely flared.

When the clutch releases, it’s better to give the handle two more rotations so you get a smooth and even flare.

Lastly, disassemble the tool depending on the type and remove the pipe.

Frequently Asked Questions

1. What’s a 410a Flaring Tool?

Such a flaring tool handles copper pipe used in the R410a refrigerant air conditioner. When you install mini-splits, you need flares on each end of the pipes to connect the condenser and evaporator.

Because these refrigerants have a high working pressure- they need tubing with deeper flares, larger diameter, and walls having at least 0.031-inch thickness. This helps in producing a stronger connection.

410a Flaring Tool gives such shape to thicker pipes. It works to create a defined 45° angle in the pipe and ensures a tight sealing between two flared ends using a nut.

2. Which Flaring Tool Would Be Ideal For HVAC?

An ideal flaring tool shapes up the pipe smoothly and precisely. It should handle different materials and sizes so you can flare multiple pipes. If you want an option, then this model by Wostore would be the best HVAC flaring tool.

It has 2 bars with 9 holes in total. The holes are compatible with the pipes that measure from 1/8 to 3/4 inches. So, it has got a broader range when it comes to the diameter of pipes.

The tool also works with different materials like aluminum, copper, plastic, brass, and thin steel. It doesn’t matter which one you use; the tool ensures even flaring.

You will also get 5 swage heads and a cutter with the tool. Both are handy and help prepare the pipe end the way you want.

3. What’s The Difference Between Swaging And Flaring Tool?

The swaging tool works to increase or decrease the tube diameter and turn the end into the desired shape, mostly cylindrical. Tools like this one include a variety of adaptors that mainly help shape the pipe end.

Meanwhile, the flaring tool also uses the pressure of a cone that expands the end of the pipe. Usually, it gives the tubing a conical shape. For instance, this tool has a cone that rotates and flares the pipe fixed to the bar.

Both tools can’t be used interchangeably despite having the same shaping process. The reason is the shape of the pipe. It has to be compatible to make the connection.

4. Can You Make Double Flare With A Single Flare Tool?

No. You can’t make a double flare with a single flare tool. If the tool lets you attach adaptors designed for such purposes, then you can. However, many single flaring tools don’t include heads for double flaring. Instead, the kit may have swage adaptors.

Meanwhile, you will find many double flaring tools with options for a single flare. Kits like this can be taken as an example. You can consider having one if you are looking for options.

Final Words

HVAC system requires strong and tightly sealable flared pipes to work smoothly. Otherwise, it can cause the entire system to fail severely even if there’s a tiny leak in the tubing.

But you can prevent that by getting the best HVAC flaring tool. It will provide you with appropriate flaring so you can make secure and leak-free connections between the pipes.

As long as you don’t have any similar tools, we recommend a comprehensive kit for the pipes. You will get not only a flaring tool but also items like swage adaptors and cutters for different purposes.
