Flare fittings are useful when the connection would require removal at times such as piping an ice maker for a refrigerator. They are used with soft copper tubing that usually comes in rolls. Below are some steps to accomplish this:
1. Cut pipe to length.
2. Insert nut onto tube.
2. Clamp flare fitting tool onto tube. Make sure that it is flush with the clamping bars. Turn screw until it bottoms out into tube.
3. Remove tool and install connection.

A flare less fitting used to connect tubing or hose.
AN fittings are a flare fitting, using 37° flared tubing to form a metal-metal seal.
I'm not sure they are from my experiences... ISO is a Bubble Flare - having a Convex (rounded) tip which mates with the concave part in the fitting -ISO brake line))ISO fitting SAE? is a double flare - having a concave tip which mates with a convex part in the fitting SAE brake line((SAE fitting I been working on my Buick which has ISO flares and a person from discount auto sold me double flare fitting for my ISO lines, i tried to put the on not knowing they were different, but they didn't fit very well. -ISO brake line)(SAE fitting I'm sure there might be a way to wrench the thing down on it to get one to bend. or maybe flare down a bubble flare so it becomes a Double flare? I'm not sure. -Brian
The best method for applying flare fitting sealant to ensure a secure and leak-free connection is to clean the fitting thoroughly, apply a thin and even layer of sealant to the flare surface, and then carefully tighten the fitting to the recommended torque specifications. This will help create a tight seal and prevent leaks.
A flare connection is a type of plumbing or fluid connection where a flared fitting is used to connect a pipe or tubing. This fitting has a cone-shaped or flared end that mates with a mating surface to create a seal. Flare connections are commonly used in refrigeration and air conditioning systems.
Double flare is a type of compression fitting used in plumbing and automotive applications. It involves flaring the end of a tubing twice to create a stronger seal when connected to a fitting. Double flare fittings are commonly used in brake line systems for their enhanced durability and leak resistance.
Flared fittings use a flare and a nipple for the sealing surface. The threads do not serve any purpose as to actually sealing anything. The threads merely hold the flare of the one fitting together tightly with the nipple of the other fitting to create a seal.
A flare joint is used on gas fittings and uses a nut and flare fitting to make the connection. This is a dry fit with no joint compound. The copper is soft enough that it compresses with the nut and forms the seal.
When you use soft copper tubing, you flare the end to make the connection. You put a nut on the tube and then flare the end so that it looks like a funnel. Then you can connect the tube to a fitting and when you tighten the nut it compresses the copper and makes a seal.
You will need a 5/8" flare nut wrench and a 1" open end wrench to access the fuel filter. To be safe, disconnect the neg battery cable from battery. Follow the fuel line to the carburetor. Slide the 5/8" flare wrench over on to the 5/8" flare nut at the end of the fuel line then slide the 1" open end wrench onto the larger fitting at the carburetor and turn the flare nut CCW from the fitting while holding the 1" fitting from turning. A small amount of fuel will run out so have some rags handy. With the flare nut removed and fuel line pulled out from the large fitting use the 1" open end wrench to remove the large fitting from carb. Take note of the order and direction of parts as they come out. Be sure the thin round nylon gasket doesn't get lost and remains attached to the inside end of the large fitting, this is what seals the fitting to the carburetor body. Reverse order to install.
Depends on how it is connected flare, compression or brazed or soldered or screwed IPS or FIPS
Use a flare nut wrench, and hold whatever it is screwed into from turning to prevent damaging the tubing
