Types Of Hydraulic Fittings

These are the different parts which assist in connection of the hose or pipe. By employing these fittings you can make up solid connection that resist leakage.

There are many types exist for hydraulic fittings. These fittings mainly depends on the material, shape, and application. The key types are as follows:

Based on the Connection Method

Depending on the connection, the types of hydraulic fittings are:

Threaded Fittings
Threaded Fittings

These fittings feature screw threads. These threads facilitate pipes or tubing secure connection. You can easily assemble these joints without any special tools. They feature wide application in plumbing and gas systems, delivering the required strength to endure high pressure.

Flare Fittings

Flare fittings have an end that narrows down, providing a perfect seal after connection. To ensure the leakage proof connections flare fittings are the perfect choice.

Compression Fittings
Compression Fittings

Compression fittings apply pressure to a ferrule or sleeve and ensure airtightness. In this fitting, you first put the nit over the tube. Later, you place the ferrule. This will ultimately ensure a safe connection.

Push-to-Connect Fittings
Push-to-Connect Fittings

You don’t need any kind of tool to setup these fittings. You just push the tubing into the fitting until you get a click that indicates a secure connection. Their very advantage lies in their ability to build connections swiftly. They are perfect for compressed air equipment or water filtration arrangements.

Quick Disconnect Couplings
Quick Disconnect Couplings

Using these couplings, you can make or break the connection as per your requirement. You don’t need specialized tooling for this connection. These couplings are suitable for pneumatic or hydraulic systems.

Welded Fittings
Welded Fittings

The welding process permanently joins the fittings together. These welds provide a strong leak-proof joint. Welded fittings serve best, especially in high-pressure and high-temperature applications. You cannot deny the role of these fittings in the gas and oil industries.

Based on Shape and Configuration

Concerning plumbing fittings, the knowledge of shapes and configurations is vital. The following section highlights information on such fittings:

  • Straight Fittings

    As the name includes, straight fittings help to join pipes or hoses vertically or horizontally without any angle or bend. They’re perfect for regular plumbing runs with a pipe end-to-end connection.

  • Elbow Fittings
    Elbow Fittings

    Please note that the elbow fittings assist in changing the flow direction. You can choose elbows that come in different angles from 450 to 900. This way you can change the direction of the hydraulic lines as well as hydraulic fluid.

  • Tee Fittings

    The Tee fittings feature a T shape. Using these fittings, you can make up branches within the hydraulic lines. You can break pne line into two lines going in different direction ar 900 to each other.

  • Cross Fittings

    The cross fittings feature an X shape after joining. These fittings lie inclined to one another. These fittings are handy when you want to make a cross-junction in your plumbing system.

  • Union Fittings
    Union Fittings

    The function of union fittings is to make it possible to quickly separate and re-connect pipes or tubes. They have three parts: two ends with threads and an internal nut that connects them. This design eases the maintenance/repairs since you do not need to disassemble the entire plumbing system.

  • Reducer Fitting
    Reducer Fitting

    Reducer fittings are those connectors that you can use to join pipes or tubes of different sizes. They have different designs, like concentric and eccentric reducers, to satisfy various plumbing roles. Like concentric reducers, eccentric reducers also maintains a central axis though the offset-centreline.

  • Bulkhead Fittings

    Bulkhead fittings feature a design for installation directly to the tanks, walls, or partitions. They enable you to create air-tight holes for pipes and tubes to pass through a barrier. In most cases, these fittings consist of a flanged nut, gasket, and compression fitting. This helps you create a secure and watertight seal.

Based on Material

You cannot deny the role of material in determining the efficiency and effectiveness of hydraulic fittings:

  • Steel Hydraulic Fittings
    Steel Hydraulic Fittings

    Steel fittings are heavy-duty and are perfect for structures such as industrial plants. This offers high durability and resistance to corrosion. Life is the factor where these fittings serve best.

  • Stainless Steel Hydraulic Fittings

    Using these fittings, you will experience no corrosion. They are fit for extreme environments, like marine or chemical industries. The strength of the stainless steel is undeniable even in higher temperature environments.

  • Brass Hydraulic Fittings

    Brass fixtures have very high conductivity levels and are prone to corrosion. You can employ them in piping and air pathways. The brass hydraulic fittings does not serve best specially in higher pressure applications.

  • Aluminum Hydraulic Fittings

    The aluminum fitting features lightweight and better corrosion resistance. However, the strength is not matchable to what steel or stainless steel offers.

  • Plastic Hydraulic Fittings

    Plastic fittings are lightweight and are resistant to rust. You can employ these fittings in lower-pressure systems where weight is crucial. The strength of the plastic fittings is not too good compared to what metal fittings offer.

Based on Application

There are multiple applications exist when it comes to hydraulic fittings. Different types suit different applications, such as:

  • High-Pressure Hydraulic Fittings

    Such fittings have been developed for hydraulic systems pressure loads. They ensure leak-proof and fail-safe connections. This fitting applies to heavy vehicles, construction machinery and hydraulic machinery.

  • Low-Pressure Hydraulic Fittings

    They are ideal for systems having lesser pressure demands. The fittings ensure safe linkage between hydraulic media like vehicles, agricultural stock and light machinery.

  • Hydraulic Tube Fittings

    These joints are hard tube friendly, guaranteeing the non-turbulent will of hydraulic fluids. They are designed for different system setups using flare or compression fittings.

  • Pipe Fittings
    Pipe Fittings

    For pipes, you can use these fittings. They come in different forms, including welded, threaded, etc. Using these fittings, you can offer reliability and strength in fittings.

  • Hose Fittings
    Hose Fittings

    You can effortlessly install these fittings. They are suitable for the cylinders, pumps, valves, etc.

Factors to Consider When Selecting Hydraulic Fittings

To select the perfect hydraulic fitting, you need to pay attention to these factors:

Operating Pressure:

The operating pressure matters while selecting a specific hydraulic fitting. Select a fitting that can bear more pressure than what your system is operating at. This way, you can get the most out of your hydraulic system in the long run.

Fluid Compatibility:

It is vital to ensure the fittings are compatible with the liquid you are using in your hydraulic system. Incompatible joints may consume or erode in the long run, causing leakages and spoilage of the fluid.

Temperature Range:

One of the crucial factors in selecting hydraulic fittings is temperature. Poor quality fittings may leak or wear especially at higher temperatures. This will ruin your hydraulic system. Therefore, choosing a fitting that can withstand too-hot or too-cold working temperatures is paramount.

Vibration and Shock:

The hydraulic system frequently faces vibrations and impact during the operation. Use components specifically designed to absorb or reduce these vibrations. This will prevent the disconnection.

Installation Method:

Contrary to different types of hydraulic fittings the installation techniques also differ. A special attention you need to pay to simplicity of the installation and the requirement of separate elements.

Environmental Conditions:

The environmental factors in which the hydraulic system functions are important to consider. For instance, pollutants, including chemicals and UV radiation or tough weather environments, can limit the life of these fittings. Specific fittings that could withstand these environmental conditions are perfect for optimum function and long life.
