What is SAE flare fitting?
Flare fittings are a type of compression fitting used with metal tubing, usually soft steel, ductile (soft) copper and aluminum, though other materials are also used. SAE fittings are typically made from brass. SAE and AN/JIC connections are incompatible due to the different flare angle.
Is SAE and flare the same?
SAE and AN/JIC fittings are completely incompatible due to the different flare angle. Furthermore, AN fittings (or those complying with subsequent standards) and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.
How do you measure SAE flare fittings?
Female connections are usually measured by inserting the gauge into the connection and placing it on the sealing surface. If the centrelines of the connection and gauge are parallel, the correct angle has been determined. Male flare type connectors are usually measured by placing the gauge on the sealing surface.
What is the difference between flare and compression fittings?
Generally speaking, compression outlets are used for water and compressed air lines, where slight leakage isn’t going to cause too much of a problem. Flared outlets are used for gas and high-pressure lines, where even a little leakage can cause major problems if left unattended.
Do you use Teflon tape on flare fittings?
Do not use Teflon ® tape or pipe sealant on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting free of grease, oil and thread sealant. Use a wrench only on the hex surfaces of the fittings.
What angle is a flare fitting?
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.
Can I use a double flare instead of a bubble flare?
Can you use a bubble flare instead of a double flare? The simple answer is no. The line and port are completely different and will not come close to sealing. When doing brake lines, you need to determine what type of flare you need for your car.
Is flare the same as NPT?
NPT or IPT pipe threads are tapered, Compression Fitting Threads are Parallel. On the other hand compression fittings and flare fittings use threads that are cut in parallel, without taper.
What thread is a flare fitting?
The SAE male has straight threads and a 45 degree flare seat. The SAE female has straight threads and a 45 degree flare seat. The seal is made on the 45 degree flare seat.
Do compression fittings need to be flared?
A flareless fitting, also referred to as a compression fitting, uses a single ferrule and a nut to make a connection, eliminating the need for flaring. Flareless fittings are common because they can be used with a wide variety of tubing types and because connections are easy to make.
Can you over tighten a flare fitting?
Fourth, don’t over-tighten the flare fitting, as this can cause leaks. Daikin offers preset flare torque wrenches that will allow you to properly tighten the flare fitting without over-tightening them. Always use a backup wrench when tightening any flare fitting.
