An Fittings - Why Are An Fittings Red And Blue?

Traditionally, AN Fittings are produced in a red/blue color combination, which served as a nod to the origin in army and navy applications for many years.

Can NPT and NPS be used together?

While NPT & NPS threads will engage and seem like they fit - they will not seal properly with each other causing leaks.

What is JIC stand for?

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.

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 is a AN fittings?

AN fittings are a particular type of fitting used to connect flexible hoses and fluid-carrying metal tubing together. The name is derived from a standardized joint agreement between the Army and Navy during World War II regarding the size specification of the fitting. A-N, therefore, stands for Army-Navy.

What size is a an fitting?

AN Size	Hose i.d. - Tube o.d.	SAE Thread Size
-2	1/8 in.	5/16 in.-24
-3	3/16 in.	3/8 in.-24
-4	1/4 in.	7/16 in.-20
-5	5/16 in.	1/2 in.-20

Is 37 flare the same as JIC?

AN and JIC Fittings Interchangeability AN 37° flare and industrial 37° flare fittings function identically. In many cases, they appear to be functionally interchangeable, but they are not.

How much pressure can AN fittings hold?

These hoses handle pressure up to 250 psi and can be used on many different parts the car.

What does JIC stand for hydraulic?

JIC 37⁰ Flares: The Joint Industrial Conference (JIC) fitting is the most common hydraulic connection style. It consists of parallel threads and a 37⁰ cone on the fitting end that attaches to either a flared tube or hose fitting.

ARE AN fittings 45 degree?

Many industrial fittings use a 45 degree flare angle. Most of the time, when you are working on aircraft, the hoses have a 37 degree flare and you don't think about the flare angle.

Is braided fuel line heat resistant?

Partschoice 20Ft 6AN Nylon Stainless Steel Braided Fuel Line has long service life, abrasion resistance and high temperature resistance.

Is hose measured by ID or OD?

Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter. As a matter of fact, that is how the hoses and tubes are differentiated.

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.

Do AN fittings need O rings?

AN fittings have straight thread, and use O-ring seals. The O-ring size is typically defined by the “AS” standard. Dash numbers are typically assigned based on the size. Boss-seal style O-rings are typically in the 900 series.

Where does the O-ring go on an AN fitting?

It seals when the O-ring is compressed into the chamfer when mating the male connection. The O-ring in an O-ring boss fitting seats between the threads and wrench flats, and is positioned around the OD of the male end of the fitting.

What size wrench fits a 6AN fitting?

ICT Billet Aluminum 6AN Wrench 6 AN Hose Fitting 11/16 Wrench Fittings Thread Lightweight Ergonomic Compact Handle Designed & Manufactured in the USA 551454.

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 size wrench is a an fitting?

These wrenches are made specifically to tighten all those expensive aluminum fittings you so proudly display on your vehicle.

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 does 6AN mean?

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"
