Features of Hydraulic Fittings

Hydraulic fittings are an essential part of the hydraulic system. In addition to ensuring that fluids move correctly, they also help to control the size of the hoses. There are a few different types of hydraulic fittings. These include flanged, flared, tapered threaded, and push-to-connect.

Stainless steel

Stainless steel hydraulic fittings are used in several different industrial applications. The material’s corrosion resistance is suitable for many harsh environments. In addition, these fittings are handy in industries that require high-pressure fluid power.

Hydraulic fittings are used to connect valves, pumps, and hoses. They can be made of a variety of materials. Stainless steel hydraulic fittings are often recommended for marine, chemical, and oil and gas applications.

For some hydraulic applications, it is necessary to use high-strength hydraulic fittings. It is a preferred choice for offshore oil and gas equipment because it offers high strength and flexibility.


A flared fitting is an angular fitting with an extended or coned end. This type of fitting is commonly used in hydraulic systems and aerospace equipment. It offers several advantages over other types of pipe fittings.

Flare fittings are easy to assemble and are widely available. They are also inexpensive. These fittings can be used for both thin-wall and medium-wall tubing.

The main features of flare fittings include a high-pressure rating, good seal reliability, and excellent vibration resistance. They can be manufactured from a variety of materials. Forged construction is particularly beneficial in cases where high pressures are expected. In addition, it provides a close grain structure, which reduces leakage.

Flare fittings are generally made from cold-drawn bar stock. They are also available in other materials on request.


If you are looking for a highly reliable connection, look no further than push-to-connect hydraulic fittings. These are easy to install and offer a leak-free seal. They are also available in a range of thread colors and sizes.

Push-to-connect hydraulic fittings are also known as push-in fittings. They are a popular choice among plumbers and other professionals because they are easy to use. With no need for adhesive or tools, they are perfect for plumbing projects.

To match any pipe size, an extensive range of fittings is available. Most are approved for underground applications. Some are specially designed for food industries.

Tapered threaded

Tapered threaded hydraulic fittings are used in several applications. They provide an effective seal for liquids, gases, and steam. In addition, they can be made from various materials. These include PTFE, cast iron, and bronze. However, they require the use of an appropriate sealant.

The most common tapered thread in North America is the NPT. A typical line is 0.75 inches per foot or 62.5 mm/m. Although it’s the most commonly used type, this thread is not recommended for the highest-pressure applications. It can also be prone to cracking if over-tightened.

Joint Industrial Council (JIC)

Joint Industrial Council (JIC) hydraulic fittings are designed for fluid power systems. These fittings offer tremendous pressure and vibration resistance and a leak-free connection. Often used in the oil and fuel delivery sectors, they are common in other industries such as automotive, aerospace, and testing.

JIC hydraulic fittings are made using various materials, including stainless steel and carbon steel. The design includes a flared nut that distributes the compressive forces evenly. Therefore, it is essential to maintain long-term reliability.

In addition, they are available in a wide range of sizes, from 3mm to 50mm. Their sleeves are also open in a variety of different outer diameters. Finally, depending on your application, you can find JIC tube fittings with sleeves from 1/8″ to 2″.

To install a JIC hydraulic fitting, cut the tubing to the desired length. Then, insert the flare nut into the connection at the end of the tubing. Once the nut has been inserted, turn it until the sealing surface is fully contacted. If necessary, apply lubricant to the nut and the connecting tube, then torque the nut.
