DESIGNED FOR: The double flaring tool kit has been designed to make double or single flares in copper, aluminum, and brass tubing as well as soft steel brake line tubing. SMOOTHER FUNCTION: This chrome-plated alloy steel swivel reduces friction. It also helps in the smooth functioning of flaring bars.

What is a double flaring tool kit used for?

DESIGNED FOR: The double flaring tool kit has been designed to make double or single flares in copper, aluminum, and brass tubing as well as soft steel brake line tubing. SMOOTHER FUNCTION: This chrome-plated alloy steel swivel reduces friction. It also helps in the smooth functioning of flaring bars.

What is double flare fitting?

The double flare is used for installations that require repeated tightening/untightening. The fitting moves against the folded over section causing that to wear and not the already thinned outer pipe wall. There is no difference between the pressure rating of single and double flares.

What is a flare tool used for?

What are Flaring Tools? Flaring tools use pressure to make a fabricated mechanical joint for joining or sealing copper tubing with a flare connection. Flaring allows you to connect tubes to each other or another kind of fitting. Flared ends tend to have an approximately conical shape.

What is the difference between single and double flare?

The single flare is very identical to the double flare. Although they look a lot alike, the double flare is much stronger and can hold more pressure build up inside the braking system. The double flare is a flare that is especially popular in vehicles imported from Europe.

Why is a flaring tool required in a rigid line fabrication?

This is necessary to prevent cutting off the flare and failure of the tube assembly under operating pressures. A double flare is smoother and more concentric than a single flare and therefore seals better.

Can you double flare steel tubing?

When flaring the tube for a 45° Double Flare, you must use a flaring tool that does a 45° Double Flare. … It’s important to use lube on the flaring tool and the tube. To create a 45° Double Flare, first clamp the tube in the correct size fixture. Set the depth by aligning the tube with the Bubble Flare die.

What are the two common types of flaring tools?

Two types of flaring tools are used to make flares on tubing: the impact type and the rolling type.

What is the difference between flaring and swaging?

Both processes have a lot of similarities. The big difference is that flaring is shallower and a different shape. It creates a funnel at the end of the tube. Swaging on the other hand is deeper and you can expand the diameter further along the tube to create a flute shape.

Do I need to double flare brake lines?

Double flares are necessary for brake lines due to the high pressures inflicted on them by the hydraulic system. Single flared lines are only appropriate for low-pressure lines due to their tendency to crack or leak.

Do you have to flare brake lines?

All brake lines need to be double flared, due to the high hydraulic pressure. If your brakes leak or the hoses crack, it could prove to be fatal. Single flared lines are suitable for low-pressure lines in other applications, but not your vehicle’s brakes.

Is a standard flare a double flare?

There are two basic types of flares used on OEM automotive brake systems throughout the world. The SAE/double (inverted/45degree) flare and the DIN/ISO bubble flare. … The most common is the SAE flare. Typically found on all American and Asian cars, but the European style DIN flare is appearing everywhere now.

Can you double flare aluminum tubing?

Aluminum tubing is very soft and malleable making it difficult to perform quality double flares. The 37 deg single flare can also be used on all 3 of the mentioned tubing types but requires that you use tubing sleeves and tube nuts to ensure a quality seal.

Can you double flare stainless steel?

The two most common falsehoods that I’m aware of are: You can’t double flare stainless, and stainless lines are more prone to leaking than standard steel lines. … This allows the two materials to re-form together and create a strong leak-free connection.

What are the three most common types of metals used for rigid fluid line fabrication in aviation?

Aluminum alloy, steel, or titanium tubing can be identified readily by sight where it is used as the basic tubing material.

What is the angle on a flare connection?

Fitting Flare Angle AN Aircraft Flare fittings have a 37 degree flare angle. Many industrial fittings use a 45 degree flare angle. Most of the time, when you are working on aircraft, the hoses have a 37 degree flare and you don’t think about the flare angle.

What actually seals the connection in a flare connection?

Design: The 37° flare AN seal is used for sealing tubing to end connections. It requires the end of the tube to have a nut slipped onto it and then flared out using a special tool. To seal properly, the nut is threaded into a flare fitting which clamps the flared tube in between the nut and flare fitting.

What does every flaring tool have?

Flaring tools consist of three main components: a metal bar with holed presets that fit different pipe or tube sizes, a screw with a handle that goes into the pipe opening to expand it as needed, and a simple metal piece that fits into the handle and enables rotation by the user.

What is a flame stack?

The tall, thin structure with flames or steam coming out of the top is called a flare stack. It’s a gas combustion device used at industrial sites to burn off waste or other unwanted gases.

Is single flare OK for brake line?

1. Single Flares are only acceptable on low-pressure lines, but not acceptable for high-pressure brake systems. A single flare is just as it sounds, the line is flared out just once in a conical shape. Single flares are not acceptable for brake lines and tend to crack and leak quite easily.

What degree are brake line flares?

The 45-degree inverted flare is the most common style of flare used in automotive hard lines like brake, fuel, and transmission fluid transfer.
