Different 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.

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.

What is the difference between JIC and BSP?

Thrust-wire fittings are either BSP (8,000 PSI proof pressure) or JIC (6,000 PSI proof pressure) and are specifically used in high-pressure, high-vibration applications.

How can you tell the difference between hydraulic fittings?

Now with these you can measure the threads to determine the fitting. Size we're going to be using

What does JIC stand for in hydraulic 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 is the difference between JIC and 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.

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.

Why is it called JIC fitting?

What does JIC stand for? JIC stands for the Joint Industries Council, which first standardized industrial use fittings. These compression couplings have a 37° flared seat on the male and female threaded connections.

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.

How do you identify an fitting?

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).

What is the difference between NPT and flare?

Also has a taper to it it gets wider as you come up the threads. It's also a different thread pitch

What is the difference between NPT and 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 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.

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).

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.

How can you tell the difference between JIC and SAE fittings?

The most common flare fitting standards in use today are the 45° SAE style, and the 37° AN style, also used with the JIC system. The AN / JIC style generally has a higher pressure rating for a given size tubing. SAE and AN/JIC fittings are completely incompatible due to the different flare angle.

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.

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.

What is JIC stand for?

JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.

What does BSP stand for in hydraulic fittings?

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.
