Have you ever heard about AN and JIC fittings? These two terms are actually often interchangeably used in the hydraulic industry. Do you know what are the differences between those two? In this article, we will give you some information about what AN and JIC fittings are, the differences between the two terms, and how Air-Way fits in.kp-lok.com
The Army Navy fittings
What does “AN” here stand for? “AN” in AN fittings, stands for Army Navy, the standards of Air Force- Navy Aeronautical Design used by U.S Army in their military applications. The AN fittings are designed to meet the high standards related to the industry of aeronautical.
AN fittings are usually used to connect metal tubing and flexible hoes where the fluid flows. The sizes of AN fittings range from dash two (-2) to dash thirty two (-32). The fittings are called flare fittings. They use 37 degrees of flared tubing, which is quite similar to JIC fittings.
The Joint Industry Council fittings
Meanwhile, the JIC (Joint Industry Council) fittings are the result of JIC standardization to the fittings, which actually have a lower quality than the AN version. It is, indeed, true that JIC fittings are considered not to be suitable for aerospace or military aviation use. However, these fittings are very suitable to be used in various construction and agricultural equipments.
JIC fittings are often used in the applications of fluid power and sometimes in fuel delivery, since these fittings are suitable to be used in the high pressure applications (more or less 10,000 psi).
Actually, the AN and JIC fittings are often used interchangeably, especially the automotive hydraulic systems, such as fuel and oil systems, and coolant systems. It is because the dimension of JIC fittings is quite similar to that of AN fittings. However the JIC fittings are less in cost and have lower tolerances.
The Differences between AN and JIC fittings
- Conical Seat Angle
Actually, both AN and JIC shares the similar standard conical seat angle, which is 37 degrees. However, JIC provides another standard that uses 45 degree conical seats, called JIC-45. Therefore, you have to make sure that all of the conical seats you use in the system are all compatible.
One of the differences that can be clearly seen between these two fittings is the threads they use. The thread used in AN fittings has a higher tolerance that can result in the improvement of its fatigue strength and shear strength.
