JIC vs SAE: What's the Difference


JIC and SAE hydraulic and hungry diagrams are common flare fittings. A flare fitting is a type of compression fitting used with metallic tubing, usually mild steel and ductile (soft) copper. Tube flaring is considered a forging operation and is usually a cold working procedure. The most common flare fitting standards in use today are the 45 degree SAE style and the 37 degree style, also used in the JIC system. Today we will discuss more details about JIC and SAE threads.


What is JIC hydraulic fittings

JIC stands for Joint Industry Council. A JIC connector is a horn connector with a 37-degree horn face as defined by SAE J514 and MIL-DTL-18866. JIC hydraulic joint is a joint used with hydraulic hose. These fittings are commonly used in high pressure fluid power applications such as hydraulically operated machinery and equipment. Especially applications involving high pressures (up to 10,000 psi).

JIC fittings are designed to provide and secure connections between hydraulic hoses, tubing, and other fluid power components. They are usually made of high-quality materials, such as carbon steel or stainless steel, and are often plated with zinc or other corrosion-resistant materials to prevent rust-type damage.


What is SAE Hydraulic Fittings

SAE stands for Society of Automotive Engineers. SAE fittings are primarily used in refrigeration, automotive plumbing and other low pressure applications. Copper tubing is usually used with SAE threads. Copper tubing is usually used with SAE threads. SAE Torch SAE male and female halves have a 45° torch holder. SAE fittings are usually made of high-quality materials such as carbon steel or stainless steel and are designed to provide a tight and strong connection. They are usually plated with zinc or another corrosion-resistant material to prevent rust and other types of damage.


What is the difference between JIC and SAE?

In some respects, JIC fittings are identical to AN (Army-Navy) fittings, but are produced to tighter tolerances and generally cost less.

Both JIC and SAE are common types of fittings used in hydraulic systems. The main difference between the two is the thread size and type they use. JIC fittings use a 37 degree flare with a 7/16 inch thread size, while SAE fittings use straight threads with a 3/4 inch thread size.

SAE 45 degree flare fittings are visually similar but not interchangeable, although panel sizes 2, 3, 4, 5, 8, 10, 14 and 16 have the same thread size. Carefully measure the seat angle to tell the difference.

Some common projects using JIC or SAE fittings include:

Fittings for connecting pipes and pipes in hydraulic systems.


How should JIC and SAE choose?

The choice between JIC and SAE fittings depends on the specific requirements of the hydraulic system they will be used in. Some factors to consider when choosing between the two include:

  • The operating pressure of the system

    JIC fittings are designed for use in high-pressure systems, while SAE fittings are better suited for lower-pressure applications.

  • The type of fluid being used

    JIC fittings are compatible with a wider range of fluids, including gasoline, diesel fuel, and hydraulic oil, while SAE fittings are limited to use with hydraulic oil.

  • The type of connection required

    JIC fittings use a 37-degree flare, while SAE fittings use a straight thread. This may affect the type of connection that is possible in a given situation.

In general, JIC fittings are a good choice for high-pressure hydraulic systems that require a tight, leak-free seal, while SAE fittings are better suited for lower-pressure applications where a straight thread is required. It's always a good idea to consult with a hydraulic specialist to determine the best fitting type for your specific application.
