Description
AN stands for Army/Navy and is the standard for many hydrauliclines used in performance hoses and accessories. AN thread sizes start at -2 up to -32, but the most common sizes are -3 to -20. The AN fttings are also known as JIC and have a UNF thread.These fitings are very popular to connect lexible hoses to accessories or hard line tube that carry diffrent types of fluid.There are two common angles used in flare fitings, 37degree and 45 degree. The fittings use these angle faces to form a seal and this must always be checked as they are not interchangeable. It is important to make sure these faces are not damaged to avoid leakage at the flare.AII AN threads are parallel and are basiclly are a flare fitting with the 37 degree face machined off and a grove for the o-ring machined.This o-ring now seals the connection. The performance industry now uses a lot of AN-ORB portsi n many applications due to it being higher flowing and better sealing than NPT.
