Male Thread Size AN Size* Equivalent Tube Size (Nominal OD)
3/8-24 3AN 3/16"
7/16-20 4AN 1/4"
9/16-18 6AN 3/8"
3/4-16 8AN 1/2"

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.

Is 6an the same as 3 8?

3AN hose has the same ID as a 3/16" tube. This means that 6AN hose will not introduce any appreciable flow restriction in a fuel system designed around 3/8" OD rigid tubing.

How do I know my fitting size?

As mentioned earlier, you can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

ARE AN fittings 37 degree?

AN fittings are a flare fitting, using 37° flared tubing to form a metal-metal seal. They are similar to other 37° flared fittings, such as JIC, which is their industrial variant.

ARE AN fittings the same as JIC?

JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

For example: a 3/8" standard hose equals -6 AN.

What does 1/2 inch IPS mean?

IPS, the way that faucet, and in most cases, uses it means Iron Pipe SIZE. I do not think I have ever seen it refer to "iron pipe straight". Even when the thread is "straight" such as faucet shanks, they still refer to it as iron pipe size.

How do I know what size fuel line I have?

Place the top of a 1/4-inch wrench with an open end over the fuel line. Slide it carefully over the line so that it fits snugly against the tubing. Read the wrench's measurements to determine the diameter of the fuel line. Place a caliper over the fuel line if the wrench did not give an accurate reading.

What is an6 fitting?

AN fittings are a flare fitting, using 37° flared tubing to form a metal-metal seal. In bolts the number refers to the diameter of the bolt whereas in a fitting it refers to the OD of the tube and thereby have different threads. For example, AN6 bolt has a ?38-24 thread whereas an AN6 fitting has a ?916-18 thread.
