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.
.
In this way, are JIC and an fittings the same?
JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. 45-degree flare fittings are similar in appearance, but are not interchangeable. Here's where people get confused.
Likewise, how do you determine your fitting size? Measure the Outside Diameter (OD) of your pipe or pipe fitting:
- 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.
Also asked, how do you measure JIC fittings?
Place the gauge on the threads until the fit is snug. Match your measurements with the tables in this guide. First measure the port hole diameter using a caliper. Next, measure the longest bolt hole spacing from center to center or measure the flange head diameter.
What size is #6 JIC fitting?
JIC 37° Flare & Uno (O Ring Boss) Threads
| MALE THREAD OD & PITCH | DASH SIZE | FEMALE THREAD ID |
|---|---|---|
| inch – TPI | mm | |
| 5/16 – 24 UNF | -05 | 6,9 |
| 3/8 – 24 UNF | -06 | 8,5 |
| 7/16 – 20 UNF | -07 | 9,9 |
What is 37 degree flare used for?
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.Do JIC fittings need sealant?
Fitting thread sealant. It cures four times faster than anaerobic sealants on stainless steel or inert metals. It works on any size NPT, O-ring boss, or JIC fitting, and prevents rotation and leakage. It seals mating surfaces of flare-style fittings, filling scratches and surface imperfections.What is the difference between JIC and NPT?
The difference is the way each thread seals. While the JIC seals on a metal-to-metal flare, the ORB seals on an O-ring, which offers the best leak free connection. NPT Pipe Threads: NPT pipe threads are your traditional tapered thread fittings and have been used for 100 years.How do you tighten a JIC fitting?
JIC fittings should be tightened by hand only until the two connecting surfaces meet. Then, fittings should be tightened with the use of two wrenches to the required number of flats. A “flat” is equal to a one-sixth rotation. To determine the required number of flats, refer to the fitting manufacturer's manual.What does an fitting mean?
Plumbing Basics - AN Fittings & Hoses. AN stands for Army-Navy. The size specifications were established by the military back in World War II. They were originally used in the aerospace industry. DO NOT use AN fittings with different flare-type fittings.What is Dash size in hose?
Simply put, a dash size refers to a diameter of a hose, tube or fitting in 1/16" increments. In this case, -6 hose would indicate a hose with an inside diameter of 6/16”, or 3/8". In another example, a -10 tube would indicate a tube with an outside diameter of 10/16", or 5/8".What size is JIC 4?
JIC 37° Flare (SAE J514)| Inch size | Dash size | Thread Size |
|---|---|---|
| 1⁄4 | -4 | 7⁄16 - 20 |
| 5⁄16 | -5 | 1⁄2 - 20 |
| 3⁄8 | -6 | 9⁄16 - 18 |
| 1⁄2 | -8 | 3⁄4 - 16 |
How do you measure thread size?
How to Determine Screw Size & Thread Count- Lay the screw down on a flat surface.
- Place a steel rule down the axis of the screw.
- Count the number of thread gaps within 1 inch of the screw.
- Divide the count of thread gaps into the length.
- Place the screw on a flat surface.
- Lay a steel rule between two screw threads and measure across the diameter.
