Hydraulic elbow fittings

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.

What are the different types of hydraulic fittings?

Types of hydraulic fittings vary depending on their sizes, configuration, and thread types. The three most common types of hose fittings are O-ring, mated angle and threaded.

Are brass fittings OK for hydraulics?

Although not one of the most common fittings used in fluid power applications, brass fittings are extremely useful in corrosive environments for both hydraulic and pneumatic hose and tubing applications.

What are the most common hydraulic fittings?

The three most common fitting ends and connector types for hydraulic fittings are the O-ring, the mated angle, and the tapered thread connectors. Although these are the most popular choices, several other types are used in different and specialised applications.

Is JIC better than NPT?

JIC fittings come with a 37O flare angle, while the NPT fittings rely on just their tapered threads for sealing. As a result, JIC fittings offer better sealing capabilities and can withstand higher working pressures.

What is the difference between JIS and JIC?

Usage difference: JIS hydraulic fttings mainly used in Japanese and Korean heavy equipment such as Komatsu, Kobelco, Hitachi, Kubota etc, often used as hose adaptors. JIC hydraulic fittings mainly used in North America market, also popular in the worldwides.

How do I know what type of hydraulic fittings I have?

There are six types of threads commonly used on hydraulic tube fittings: UN/UNF. NPT/NPTF. BSPP (BSP, Parallel) ... Four Steps to Thread Identification

Step 1 – Determine if the thread is tapered or parallel.
Step 2 – Determine the pitch. ...
Step 3 – Determine the size. ...
Step 4 – Designate the thread.

How do I know if my hydraulic fittings are JIC?

Four steps to know if your fittings are JIC:

Identify if the thread is parallel or tapered. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
Determine the flare angle by using a calipers.
Determine the thread diameter. ...
4.Identifying the thread by gauge.

What is the difference between JIC and SAE fittings?

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, and 10 share the same thread size.

Can you use pipe fittings for hydraulic fittings?

Pipe thread is unique; it is a tapered thread that both holds the fitting in place and creates the seal. But pipe threads are not the best choice for high-pressure hydraulic connections as they are susceptible to vibration. An O-ring seal connection method is preferred for high-pressure applications.

Does brass withstand high pressure?

Brass can accommodate pressures to 3000 psi depending on the design and size of the fitting. However, most brass fitting applications are rated for lower pressures.

Will galvanized pipe work for hydraulics?

It is important to remember that galvanized pipe is not recommended for use in hydraulic systems, therefore should never be used. When sizing a pipe one should remember that the “Nominal Pipe Size” (NPS) is the system that is used.

What is the best type of hydraulic fitting?

To address high operating pressure, more and more of our customers prefer to use O-ring seals. They are more resistant to cracks. O-ring seals also prevent the risk of over-torqueing and leakage. In terms of material stainless steel hose fittings have the highest pressure rating.

How do I know what size hydraulic fitting?

You would first measure the OD of the male. Or idea of the female. Once you have established the

How do I know what size hydraulic fittings I need?

First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it. Next, determine the outside diameter of the fitting by using your ID/OD calipers.

Do JIC fittings need O rings?

Most commonly used as hydraulic fittings in the fluid power industry, JIC (Joint Industry Council) fittings are a type of flare fitting machined with straight threads using a 37° flare seating surface. This is used to form the seal of the fitting instead of an o-ring or tapered threads.

Can you mix JIC and an fittings?

JIC Steps In The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

Are SAE and JIC fittings interchangeable?

SAE and AN/JIC fittings are completely incompatible due to the different flare angle. Furthermore, AN fittings (or those complying with subsequent standards) and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.

What does JIS fitting stand for?

» Technical » Thread & Connector Guides » JIS Threads. Japanese Industrial Standards (JIS) Threads. JIS Threads. JIS. Japanese Industrial Standards.

Is UNF and JIC the same?

Commonly referred to as just JIC fittings these metal to metal sealing type fittings have a 37° flare (sealing surface angle) and straight United National Fine straight Threads (UNF).
