What Are Hydraulic Fittings

Hydraulic fittings are an integral component in hydraulic systems. They connect different hydraulic components, ensuring that fluid can flow seamlessly through the system. With a variety of hydraulic fittings available on the market, it can be challenging to know which fittings to use in different situations. In this article, we will discuss the different types of hydraulic fittings available and their uses.

 

1. JIC Fittings

JIC (Joint Industry Council) fittings, also known as AN fittings, are a popular type of hydraulic fitting for many hydraulic systems. It's quite popular in North American markrt. This type of fitting incorporates a 37-degree flared end, creating a tight and reliable seal. They are used extensively in high-pressure applications, such as hydraulic systems in agriculture, construction, and mining. JIC fittings are also reusable, making them cost-effective, so NJ also offer resuable JIC hydraulic fittings for 100R1, 100R2 & 100R5 rubber hose.

 

2. NPT Fittings

National Pipe Thread (NPT) fittings are another widely used type of hydraulic fitting. They feature a tapered thread that creates a tight seal when attached to a female NPT fitting. NPT fittings are commonly used in low-pressure hydraulic systems, such as air compressors and water pumps, but can also be used in high-pressure applications.

NJ not only offer NPT fittings, but also offer NPTF fittings, comparing NPT thread, the sealing performance of NPTF will be much more better.

 

3. O-Ring Face Seal Fittings

ring face seal fittings, also known as ORFS fittings, use an O-ring on the face of the fitting to create a seal. ORFS fittings have two key benefits: they have a high-pressure rating and can be easily assembled and disassembled. They are commonly used in high-pressure hydraulic systems, such as those used in heavy machinery and industrial applications.

For orfs fittings, we offer nitrile o-ring and vition ring, because most customers require high temperature resistance.

 

4. O-Ring Boss Fittings

O-Ring Boss fittings are a type of hydraulic fitting that features a specialized sealing surface for use with O-rings. This sealing surface helps to create a leak-free connection between two hydraulic components, ensuring that the system remains in proper working order. O-Ring Boss fittings are commonly used in applications where high pressure and fluid flow rates are involved, such as in hydraulic systems for industrial machinery or heavy-duty equipment. These fittings are available in a wide range of sizes and configurations, offering flexibility and adaptability to meet the unique needs of any system. Invest in high-quality O-Ring Boss fittings for long-lasting, reliable hydraulic connections. NJ offer o-ring boss hose barb fittings, and o-ring boss adjustable fittings.

 

5. DIN Fittings

Deutsche Industrial Norm (DIN) fittings are a fitting type similar to JIC fittings but with a metric thread. DIN fittings are less commonly used in North America but are more prevalent in Europe. DIN fittings are suitable for high-pressure applications and are also available in reusable and non-reusable options.

NJ offer various sealing type of them, such as 60 degree cone, ED ring, bonded seal, o-ring+retaining ring, bite type.

 

6. SAE Fittings

Society of Automotive Engineers (SAE) fittings are specific to the automotive industry and are used for brake and transmission lines. They feature a flared end with a thread formed at a 45-degree angle. SAE fittings are rated at high pressures and can be either reusable or non-reusable.

Besides SAE adapters, we also offer SAE 45 reusable hose fittings.

 

7. BSP Fittings

British Standard Pipe (BSP) fittings are a popular type of hydraulic fitting in Europe. They are used in low to medium pressure systems and feature a parallel thread that creates a tight seal. BSP fittings can be either male or female and are available in different types of thread forms. And BSP thread includes BSPP and BSPT, it depends on your requirements.

 

8. Metric Fittings

Metric hydraulic fittings are used primarily in Europe and other countries that use the metric system. They are interchangeable with other types of fittings, making them versatile. Metric fittings are available in many forms, such as JIC, NPT, and BSP, allowing them to be adapted to various hydraulic applications.

 

In Summary

There are several types of hydraulic fittings available, each with its unique characteristics and applications. When selecting a hydraulic fitting, it's essential to consider the system pressure, the fluid compatibility, and the fitting type. It's also important to source reliable hydraulic fittings from a reputable supplier to avoid potential system failures or leaks. NJ usually offer steel hydraulic adapters, but also provide stainless steel adapters and brass fittings. They offer a variety of connection options and are often used to adapt hose sizes or to connect different types of fittings. By selecting the right hydraulic fittings for your system, you can ensure optimal performance and safety.
