Although they look similar and have similar functions, there are several differences between the JIC/ SAE J514 fittings and the AN 37° flared fittings. These differences include: Threads

AN fittings offer excellent hose flexibility, which is crucial in performance applications. The flexible hoses connected to the AN fittings can bend and move without causing any damage to the fittings, which is essential in high-vibration applications. Leak-Free Connections Today, AN fittings are widely used in various industries and applications, including automotive and aerospace. Understanding AN Fitting Sizes It's time to upgrade your engine bay with Mishimoto -AN braided lines and fittings. Mishimoto has released an extensive lineup of -AN line fittings, unions, reducers, and adapters to help complete your project. Each CNC-machined 6061 aluminium fitting features a corrosion-resistant anodized finish, providing a very sleek yet subtle appearance. Mishimoto -AN line ends feature a full 360-degree swivel, making routing and final install a breeze. Mishimoto -AN aluminium adapters and reducers make transitioning to other line sizes and types painless. Our braided line fittings are engineered to withstand substantial abuse, including extreme temperatures and high pressure.

For example, an “AN6″ fitting has a nominal size of 6/16″ and a thread size of 3/8”-24. On the other hand, an “AN8″ fitting has a nominal size of 8/16″ and a thread size of 7/16”-20. AN fittings are designed to provide leak-free connections, ensuring that fluids or gases are contained within the system. This is particularly important in applications where the safety of the system or the environment is a concern. Durability Brake systems are critical components in any vehicle, providing the necessary stopping power. AN fittings are often used in high-performance brake systems, as they can handle high-pressure brake fluid and provide a leak-free connection. Advantages of Using AN Fittings So remember: dash size is the size of hose, tube or fittings expressed in sixteenths of an inch. Hoses are measured by inside diameter, and tubes are measured in outside diameter.

AN and JIC (SAE J514 standard) both have a 37° flare connection on the male and female sides of the fitting and straight threads. A seal is achieved by threading in the JIC male flared connection with the female coned connection.Not only are there differences in the thread and standards of production. Materials differ as well. AN fittings are available in a variety of materials, including aluminum and stainless steel. It’s important to choose the right material for your application, based on factors such as strength, weight, and resistance to wear and tear. Brand AN fittings are available in a variety of shapes and designs, including straight, 45-degree, and 90-degree elbows, and tees. You can use these fittings in a variety of applications, including: Fuel Lines The terms AN and JIC are used interchangeably in aftermarket automotive hydraulic systems. Mainly the system is used for fuel and oil systems. Occasionally it is also used for coolant systems, but it is pretty rare. What we’re after in reality are AN fittings, because they offer the best dimensional tolerances, and sealing surface finishes. Not all fittings that look the same, are the same! In Motorsport ¶

The unique design of AN fittings features a 37-degree flare at the end of the fitting, which provides a secure and leak-free connection with a compatible hose. With a range of sizes and designs available, AN fittings are suitable for a variety of applications and provide numerous benefits, including flexible hose connections, leak-free connections, and durability. A new standard was introduced to clean up the confusion called the JIC (Joint Industries Council) fitting standard. These JIC hydraulic fittings have a slightly lower class of thread quality and are considerably less expensive than their AN counterparts. AN fitting sizes and JIC fitting sizes are comparable. JIC fittings are now defined by standard SAE J514 of the Society of Automotive Engineers (SAE). Differences between AN and JIC fittings SAE fittings are commonly used in traditional automotive applications, such as in brake and fuel systems. They can also be found in older vehicles and in some industrial applications that do not require the high performance capabilities of AN fittings. Aeroquip are one of the biggest suppliers of these type of fittings to the motorsport industry. They are sold by quite a few people. Think Automotive in London sell the majority of the Aeroquip range.

It’s important to note that AN fittings are designed to fit a specific hose size. Therefore, it’s crucial to choose the correct size fitting for your specific application to ensure a proper and secure connection. Power steering systems use hydraulic pressure to make steering easier, especially at low speeds. AN fittings are commonly used in power steering systems, as they are designed to handle high-pressure hydraulic fluids and provide a leak-free connection. Brake Systems Generally the fittings in motorsport are compatible with the AN / JIC standards, but rarely do you see anyone claiming they sell AN or JIC fittings, in fact they normally say that they sell “re-usable fittings” Did you notice that for hose part numbers, we talked about inside diameter, and for tube part numbers, we referred to an outside diameter? This is not an accident. Hoses are measured by inside diameter, and tubes are measured by outside diameter, which is how they are differentiated from each other. Most people think about hoses as being flexible and tubes as being rigid, but in fact, there are some very rigid hoses, and some very flexible tubes. For example, nylon tubing is very flexible, and flexible metal hoses are (relatively) very rigid.
