Considering this, what does an fitting mean?
The AN thread is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN.
Also to know, what is an fitting size?
Each AN size refers to the outer diameter (o.d.) of the tube, or inner diameter (i.d.) of the hose that it's used with. The numbers assigned equal the size in 1/16 inch increments. Each AN size also has its own standard thread size.
ARE AN fittings NPT?
Non-Tapered Thread. Aside from thread sizes, the most important difference between AN and NPT threaded fasteners is that NPT uses a tapered thread. On the other hand, AN fittings are flare-type compression fittings and, as such, don't require any form of thread sealant.
What does an6 mean?
AN6 refers to 6/16 outside diameter (OD) of the tube. Hence the tube would have an OD of 3/8". The inside diameter (ID) of the tube is not specified under this system, hence the ID can vary depending on the application and material there is a way of determining this too, depending on material etc.
