Choosing the right fittings for a hydraulic system depends on several key factors, such as the pipe material, the system's operating pressure and temperature, and the type of medium. Consider the type of connection (screwed, crimped, soldered), as well as the specifics of the specific system component (e.g., elbows, tees). The market offers a wide range of hydraulic fittings and fittings, and their selection depends on many factors, such as the pipe material, type of installation, and operating conditions. Below, we present the most common types of hydraulic fittings, their applications, and key information worth knowing.

Criteria for selecting hydraulic fittings

Medium type and parameters

Determine whether the system will transport water, gas, or other substances. Consider the operating temperature and pressure, which will influence the selection of fitting material and design. The application of a fitting must be in accordance with its specifications. A fitting for steel pipe will be different than a fitting for copper pipe. Understanding the application and installation requirements allows you to select the appropriate components. Please remember that:

• For water installations, choose materials that are safe for health.
• In heating installations, pay attention to resistance to high temperatures.
• In industrial systems, consider resistance to chemicals.

Pipe Material

Fittings should be compatible with the pipe material (copper, brass, plastic, steel). Avoid combining dissimilar metals to prevent corrosion. Hydraulic fittings should be made of a material appropriate for the operating conditions and the medium flowing through the system. High-quality materials such as copper, brass, stainless steel, or high-quality plastics ensure durability and reliability. Questions worth asking yourself:

• Is the material corrosion-resistant?
• Does it withstand the expected pressures and temperatures?
• Is it compatible with the medium (water, gas, oil)?

The right material selection is key to a long-lasting installation.

Connection type

• Screwed: easy to install, popular in home installations.
• Clamped: ensures durability and tightness, popular in PEX systems.
• Soldered: used mainly in copper installations, requires soldering experience.

Depending on your needs, you can choose from various types Connections:

• Threaded
• Soldered
• Compression
• Glued

For example, a threadless steel pipe fitting allows for connection by welding or crimping, which can be advantageous in certain situations. The choice of connection type affects the ease of installation and the tightness of the installation.

Types of fittings by thread type

• Metric thread: standard thread used in many installations.
• Inch thread (BSPP, BSPT): used in various standards, e.g., British.
• American thread (JIC, NPT): popular in the United States.
• UNF thread: used in automotive and aviation.

Types of fittings

• Straight: used to connect straight sections of pipe or hose.
• Elbow: allow for changing the flow direction at an angle.
• Tees and crosses: used to branch hydraulic installations.
• Reducers: allow for connecting pipes or hoses of different diameters.
• Nuts, sleeves, Nipples: connecting elements with various thread configurations.
• Quick couplers: allow for quick and easy connection and disconnection of hoses without tools.
• Mushroom head: popular in agricultural machinery.
• Flat-face: universal, used in many hydraulic systems.
• Screwed: older type, used in older machinery.
• Push-pull: easy to use, allow for quick connection and disconnection even under pressure.

Certifications and standards for couplers

Choose couplers with appropriate certificates and that meet safety standards.

Additional tips:

• Choose couplers from the same manufacturer as the pipes to ensure compatibility of materials and parameters.
• Check the tightness of connections after Installation.
• For installations exposed to vibration, choose reinforced connectors.
• Consult a specialist if you have any doubts about the selection of connectors.
