Hydraulic hose fittings types

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.

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.

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 hydraulic fittings?

Four Steps to Thread Identification

Step 1 – Determine if the thread is tapered or parallel. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
Step 2 – Determine the pitch. ...
Step 3 – Determine the size. ...
Step 4 – Designate the thread.

What is a JIC 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.

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.

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.

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 you identify a hydraulic hose?

The best way to check is to measure the taper angle or screw a known fitting into the hose. You can also check thread pitch and diameters to confirm things. Identify the thread as BSP, Metric or JIC flare etc. Identify the thread size.

How many types of hose fittings are there?

These three types are either metal seal, soft seal, or tapered thread connectors.

How many types of hydraulic hoses are there?

You've essentially got three options: rubber with metal wires, thermoplastic with textile reinforcement, or Teflon with stainless braid. There are a few other application specific specs out there, and we'll talk about them in a bit, but, really, those are your three options.

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.

How do you read hydraulic hose fittings?

To identify the size of the thread you would first measure. The OD of the male. Or idea of the

Are all hydraulic quick connect fittings the same?

Q: Are all quick couplers the same? A: No, there are two primary construction styles for hydraulic quick couplings. The check valve style system uses either balls or poppets to block flow from exiting the fitting.

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.

What is the difference between SAE and JIC?

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.

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).

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 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.
