An Fitting Thread Pitch
What is an a thread?
The AN thread (also A-N) 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.
What are the AN fitting sizes?
AN fittings range in size from -2 (dash two) to -32 in irregular steps that each equates to the outer diameter of the tubing. The outer diameter of the tube or hose that each fitting is to be used for is correlated with the inner diameter of the fitting itself.
What angle is a an fitting?
The U.S. Air Force, with help from Wright Patterson Air Force base, developed a fitting with 37° flare angle, before WWII, which became known as the "AN" fitting.
ARE AN and NPT the same?
Aside from thread sizes, the most important difference between AN and NPT threaded fasteners is that NPT uses a tapered thread. That's a fancy way of saying the bolt is actually slightly smaller at the tip than the base. It's designed that way to firmly seat the male and female threaded ends together.
What thread is 6AN?
| Male Thread Size | AN Size* | Equivalent Tube Size (Nominal OD) |
|---|---|---|
| 9/16-18 | 6AN | 3/8" |
| 3/4-16 | 8AN | 1/2" |
| 7/8-14 | 10AN | 5/8" |
| 1 1/16-12 | 12AN | 3/4" |
How do you read an fitting?
So the am system often abbreviated to - fittings Anna - fittings are exactly the same is based off
Why do some AN fittings have O rings?
When two parts of a fitting are joined, the O‑ring is compressed to create a tight, leak proof seal. While simple in design, O‑rings are a critical component in a variety of pressure systems found in industrial, agricultural, and automotive applications.
What is a 12 AN fitting?
| AN Size | Hose i.d. - Tube o.d. | SAE Thread Size |
|---|---|---|
| -12 | 3/4 in. | 1 1/16 in.-12 |
| -16 | 1 in. | 1 5/16 in.-12 |
| -20 | 1 1/4 in. | 1 5/8 in.-12 |
Why use an AN fitting?
People use AN fittings because they look cool and provide a secure fitting that seals hoses better than traditional push on nipples and hose clamps. They form a serviceable connection that provides a reliable seal.
What size is 6AN hose?
Product detailsProduct details. [Size] ID of 6an fuel hose:0.34"(8.63mm),OD:0.54"(13.71mm).
ARE AN and JIC fittings interchangeable?
JIC Steps In The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.
What is the difference between an and AC fittings?
The AN fitting has a shoulder between the end of the threads and the flare cone. (See figure 5-6.) The AC fitting does not have this shoulder. Other differences between the AC and AN fittings include the sleeve design, the AC sleeve being noticeably longer than the AN sleeve of the same size.
What thread is AN8?
AN8 bolts have a 1/2-20 thread with a 1/2" shank diameter. All AN8 bolts have a 0.781 inch thread length regardless of bolt length. This thread length is designed specifically to allow the use of a full-height nut plus one AN960-816 flat washer.
Is JIC 37 or 45?
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface.
Can you use BSP with NPT?
If you are looking to connect a BSP pipe to an NPT pipe, it won't work. The reason they don't fit together is that their individual thread designs are different. The NPT design has a 60° angle and the "flattened peak and valley" design pioneered by Sellers.
How do you identify BSP and NPT threads?
NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form).
Is NPT same as SAE?
What's the difference between SAE & NPT threads? The biggest difference is SAE is a straight thread, it needs additional O-ring, gasket or sealing surface to form a seal; NPT thread is a taper thread, it can form a seal using its thread pitch.
What is an an fuel fitting?
AN Fittings are aluminum plumbing components and adapters used in the automotive performance and racing industry to connect stainless steel hoses for fuel systems, coolant, air, water, and oil.
What size is SAE 6?
| Inch size | Dash size | Thread Size |
|---|---|---|
| 5⁄16 | -5 | 1⁄2 - 20 |
| 3⁄8 | -6 | 5⁄8 - 18 |
| 1⁄2 | -8 | 3⁄4 - 16 |
| 5⁄8 | -10 | 7⁄8 - 14 |
