I've ordered hard to find metric electrical connectors from here with luck: Oil Filter Services in Portland has helped me out with din flared fittings before, used on 80's Bosch mechanical fuel injection. Though they have identical dimensions, JIC fittings should not be confused with AN (Army Navy) fittings, and the two should not be considered functionally interchangeable. As the male and female fittings are joined, they assemble without interference. JIC fittings now come in a multitude of variations that are easy to adapt to both imperial and metric, allowing them to fit virtually any hose or port and making them universally accepted by both foreign and American companies. Being unable to convert between different ways of expressing thread measurements can be a costly problem. In turn, this causes a reduction in flow diameter. I've been surprised every time I call with some off the wall fitting. Our JIC fittings are available in two styles: SAE 37 Flared and the modified UltraFlare version, which includes a primary PTFE seal, reinforced by the metal-on-metal seal which increases performance in mild vacuum and moderate vibration on thin and medium-walled tubing systems. Also, the combination of male a JIC fitting and female JIC swivel make orientation much easier. Are a JIC and AN hydraulic fitting the same thing? There are three components that make a tubing assembly; fitting, flare nut and sleeve. JIC fittings, also called SAE J514 hydraulic fittings, play an essential role in everyday applications. Montreal The Joint Industry Conference (JIC), an organization of manufacturers, decided to standardize on the "AN" design, except with 2A/2B thread class for ease in manufacturing. AN fittings were developed by the Air Force and Navy (hence AN) and are supposed to be manfactured to tighter tolerances than JIC. AN 37 flare and industrial 37 flare fittings function identically. The fitting became an ISO standard, ISO 8434, in 1986, replaced by ISO 8434-2 in 1996. Posted by In the 1960s, several versions of 37 flare fittings flooded the industrial market, all claiming the AN standard, creating a nightmare for the users. Even though they don't list the fitting on their site (yes it sucks) give them a call. Specific applications (such as high-vibration applications) have a lower pressure rating than is required. It will also serve as a secondary reference point to check the tightness of the connection over time and serve as a reminder to reconnect after maintenance. Its important to note that the AN and JIC specifications are no longer in existence in most cases. UNC, UNF, and UNEF threads are almost identical to UNJ, UNJC, UNJF, and UNJEF threads. Ningbo, China For these reasons JIC and AN fittings are not functionally interchangeable and so care needs to be taken to properly identify your connection to create a safe and leak resistant seal.
