Defined by MIL-F-18866 and SAE J514 standards, these flare fittings have been machined to have a 37° flare seating surface. These fittings are most commonly used in fluid power and fuel delivery applications, especially those using high pressure.
The most common flare fitting standards in use today are the 45° SAE flare, the 37° JIC flare, and the 37° AN flare. SAE 45° flare connections are commonly used in automotive applications as well as for refrigeration and air conditioning. SAE fittings are typically made from brass.
Thereof, How are flare fittings measured?
1) With a caliper, measure the thread diameter at the widest point across the threads (See image below). Outside diameter (O.D.) of male threads. Inside diameter (I.D.) of female threads. … For example, a 3/8” male flare has an actual outside diameter of 5/8”.
Also to know is, How do you tighten a flare fitting? Use a drop of clean refrigeration oil on the back side of the flare to allow the nut to turn without twisting the tube. 4- Yellow Jacket torque wrench, part number 60652, offers the preset flare torque. Allowing you to properly tighten the flare fitting without over tightening them.
Subsequently, question is, How do you flare 3/8 copper tubing?
Also, How do you size a compression fitting?
To measure a threaded fitting, measure the thread diameter at the widest point across the threads. For a non-threaded fitting, measure the actual insert opening diameter or tube being inserted into the compression sleeve.
What are the two standards for flare fittings?
The most common flare fitting standards in use today are the 45° SAE flare, the 37° JIC flare, and the 37° AN flare. SAE 45° flare connections are commonly used in automotive applications as well as for refrigeration and air conditioning. SAE fittings are typically made from brass.
ARE AN fittings 37 degree?
Technically speaking, AN fittings are manufactured to MIL-F-5509, and industrial 37-degree flare fittings are manufactured to meet SAE J514/ISO-8434-2.
How do you measure for compression fittings?
What is the flare end of a fitting?
A flared outlet also uses a nut and the fitting, but in this case, it’s the end of the pipe itself that creates the seal. Once the nut is placed on the pipe, a special tool called a flaring tool is used.
What is the angle on a flare connection?
The most common flare fitting standards in use today are the 45° SAE flare, the 37° JIC flare, and the 37° AN flare. … SAE fittings are typically made from brass. SAE and AN/JIC connections are incompatible due to the different flare angle. JIC 37° flare connections are used in higher pressure hydraulic applications.
How does a flare fitting work?
Flared Outlets: It’s placed around the diameter of the pipe near the end in a hole appropriate to that size of pipe, with a flared shape that will form the flare. Once it’s secured, another tool is put into position that, when screwed down, will deform the pipe, creating a flare or cone at the end.
What does JIC mean?
Just in Case
What is a 37 degree flare fitting?
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.
How do you determine your fitting size?
– Wrap a string around the pipe.
– Mark the point where the string touches together.
– Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
– Divide the circumference by 3.14159.
What is a standard 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.
How tight should flare fittings be?
Generally, the tubing should stick up about 1⁄16 in. This ensures that the block grasps the tubing tightly. After tightening the screws, spin the mandrel into the tubing, tighten it by hand, and check how the flare mates with the fitting.
Do flare fittings need Teflon tape?
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.
