AN fittings come in a variety of sizes and are typically identified by their AN size (e.g. AN-6, AN-8, AN-10, etc.). 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 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 Then JIC (The Joint Industry Council) came along and use the AN standard as a basis for their own standard. They essentially just ratified the parts to reduce the part count. The tolerances allowed are more lenient for JIC fittings too, compared to AN fittings.
Although developed and produced to a lower standard, JIC and SAE fittings are nearly identical to AN-type couplings. These are used extensively in agricultural equipment, construction, heavy machinery, and automotive industries. What does a class 1A and 1B thread fit mean? AN fittings and SAE fittings are two commonly used types of fittings in the automotive industry. Understanding the difference between the two is important when it comes to selecting the right fitting for your needs. AN Fittings Fuel lines are an essential component in any vehicle, providing the necessary fuel to the engine. AN fittings are commonly used in high-performance fuel systems, as they are designed to handle high pressures and provide a secure connection. Oil Coolers AN fittings are made to a much higher standard than JIC/SAE fittings. Also, AN fittings are much more expensive. Using these interchangeably is not recommended. What are AN fittings used for?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
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. People that are new to the hydraulic and pneumatic industries often ask: What is a dash size? Simply put, a dash size refers to a diameter of a hose, tube or fitting in 1/16" increments.
AN Fittings vs SAE Fittings: Key Differences
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
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

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. The line drawings below depict the actual sizes of the various common types of fittings, hose ends and adapters. The number is SAE spanner size equivalent.
AN fittings are made of high-quality materials, such as aluminum or stainless steel, which makes them highly durable and resistant to wear and tear. This is particularly important in applications where the fittings will be exposed to harsh conditions, such as high pressures, temperatures, and chemicals. How are AN fittings installed? One of the most important aspects of AN fittings is understanding the sizing. AN fittings are available in a range of sizes, each with a unique designation. The size of an AN fitting is indicated by two numbers separated by a dash, such as “AN6” or “AN8.” The first number refers to the size of the fitting, while the second number refers to the thread size.As mentioned earlier, AN fittings are designed to fit a specific hose size. It’s important to choose the correct AN size fitting for your specific application to ensure a proper and secure connection. Application Requirements Fittings are a little different and slightly more complex. In the part number 10343 -8 -6, for example, -8 is the size of the fitting end connection, and -6 is the hose size. Originally parts were made compliant to the specification MIL-F-5509, but they are now controlled under SAE AS (Aerospace Standards) specifications AS4841 through AS4843 and AS4875. Oil coolers are used to keep engine oil at the proper temperature, which helps to extend the life of the engine. AN fittings are often used in oil cooling systems, as they are designed to handle high-pressure oil and provide a leak-free connection. Power Steering Systems The number represents the OD (Outside Diameter) of the tube the fitting was designed to fit in the old AN specifications. The number represents the OD as multiples of 1/16”. Therefore, a -10 fitting was originally designed to fit an solid tube with an OD of 10 * 1/16″ = ⅝″ (~16mm). Conical Seat Angle ¶
