Hydraulic fittings Manufacturers online

Hydraulic fittings provide a reliable connection in hydraulic systems for hoses, pipes and other components.

These fittings ensure tight connections that can withstand high pressures. They are indispensable in a variety of industrial applications.

Below you will find types, the main areas of application and the benefits of hydraulic fittings:

Types of hydraulic fittings:

1. Screw fittings:
Structure: Consist of an internal and an external thread, which are provided with a seal.
Function: Tightening the fitting creates a tight connection that can withstand pressure and leakage.

2. Flanges:
Structure: plates with holes for attachment to another surface, often with a sealing surface.
Function: Flanges allow easy assembly and disassembly of pipes, ideal for larger systems.

3. Compression fittings:
Design: a clamping device that holds the conduit securely in place.
Function: They provide a quick and easy connection that can often be made without special tools.

4. Fittings with O-ring:
Design: a seal in the form of an O-ring is inserted between the connecting parts.
Function: This type provides an effective seal and can better compensate for pressure and temperature changes.

5. Hose fittings:
Design: Specially developed for hose lines, often with a conical internal thread.
Function: They provide a secure connection between a hose and another component, such as a cylinder or pump.

Main application areas of hydraulic fittings:

1. Manufacturing and industry:
In hydraulic presses, hoists, conveyor systems and injection molding machines to ensure safe power transmission there.
Used in automated production lines where hydraulic systems control various movements and processes.

2. Construction industry:
Used in construction machinery such as excavators, cranes and bulldozers to connect hydraulic lines that control cylinders and motors.
Used in hydraulic drives and control systems of heavy-duty machinery.

3. Agriculture:
In tractors, harvesters and other agricultural equipment for power transmission and control.
Connection of hydraulic hoses for the operation of plows, trailers and other attachments.

4. Automotive industry:
In braking and steering systems of vehicles where hydraulic pressure lines are used.
Connecting hydraulic lines in trucks, buses and special vehicles.

5. Energy and utility industry:
Used in hydraulic drives and control systems in power plants and utility grid maintenance.
Used in wind turbines and other renewable energy systems that use hydraulic controls.

Advantages of hydraulic fittings:

• Designed to withstand extreme pressures that occur in hydraulic systems.
• Provide tight connections that prevent hydraulic fluids from leaking.
• Compatible with various pipe and hose types and materials, including steel, stainless steel and plastic.
• Allow quick and easy installation and replacement of components.

Hydraulic fittings are essential components that ensure the safe and efficient operation of hydraulic systems in many industries. They provide reliable connections that meet the requirements of high pressures and demanding operating conditions.

Here are the most important aspects to look out for when buying hydraulic fittings:

When purchasing hydraulic fittings, there are several important factors to consider in order to make the right choice for your specific application. These components are critical to the safety and efficiency of hydraulic systems:

• Hydraulic fittings are typically made of steel, stainless steel, brass or plastic. The choice of material depends on the application and the environment.
• In corrosive environments (e.g. in the offshore industry), fittings made of stainless steel or with special coatings (e.g. zinc-nickel) should be selected to ensure a long service life.
• The fitting must be able to withstand the maximum operating pressure of the system. Pay attention to the manufacturer's pressure specifications, which are given in bar or PSI.
• Make sure that the fitting is suitable for the temperature range in which the system is operated. High temperatures require special materials or seals.
• The size of the fitting must match the size of the hoses or pipes in the system. common sizes are specified in inches or millimeters.
• Ensure that the correct thread (metric, BSP, NPT, etc.) matches the application and the existing components.
• Different seals (e.g. NBR, Viton, PTFE) are required depending on the medium and temperature range.
• Fittings can be equipped with different types of seals, such as O-rings, flat gaskets or metallic seals. Choose the right type of seal for your application.
• Pay attention to international standards and certifications such as ISO, DIN or SAE, which vouch for the safety and quality of the products.
• Take into account environmental factors such as humidity, chemicals, UV radiation or vibrations, which can influence the choice of material and design.
• In mobile applications or under heavy mechanical stress, robust and vibration-resistant screw fittings should be selected.
• Ensure that the fittings are compatible with the existing hydraulic components (hoses, pipes, pumps).
• Fittings should be selected so that they are easy to assemble and disassemble to facilitate maintenance work.

When purchasing hydraulic fittings, material quality, pressure and temperature resistance, accuracy of fit, sealing materials and manufacturer quality are crucial to ensure the safety and efficiency of the hydraulic system.

Hydraulic fittings can be purchased from various suppliers. You will find comprehensive information on manufacturers and suppliers of Hydraulic fittings around the world on Exportpages.
