Criteria for selecting threaded and soldered fasteners

Selecting the right connectors is a key element of installation design.   At Onninen, we attach great importance to this. We advise our clients, taking into account a number of important factors. The first of these is the type of medium flowing through the installation. We will choose a different connector for water, and a different one for gas or oil.

Another important aspect is the system's operating pressure. The connectors must withstand maximum loads. The operating temperature is also a key parameter. It influences the choice of connector material. Resistance to corrosion and aggressive substances is also important. In some cases, stainless steel connectors are necessary.

From our experience, it is worth paying attention to:

• Compatibility with other installation elements
• Easy to assemble and disassemble
• Durability and wear resistance
• Ability to work in changing conditions
• Certificates and approvals for specific applications

At Onninen we offer products that meet the highest standards. They guarantee safety and reliability of the installation. Our specialists will be happy to help you choose the optimal solutions.

Practical applications of threaded and soldered fasteners

Threaded and soldered fasteners are widely used in various industries.   In residential construction, they are essential for water and heating installations. Industry uses them in hydraulic and pneumatic systems. The automotive industry uses them in brake and fuel systems.

We recently completed a project for a large manufacturing plant. The customer needed connectors that were resistant to high temperatures. We used special connectors made of a copper and nickel alloy. They proved to be excellent in difficult working conditions. This is an example of how selecting the right connectors affects the efficiency of the entire system.

When modernizing older installations, compatibility issues often arise. The transition connectors we offer allow you to connect different systems. They enable the integration of new elements with older infrastructure. This is an economical and practical solution for many customers.

ZKT type shock absorbing connectors are very popular.   They are used in installations exposed to vibrations and oscillations. They prevent the transfer of unwanted vibrations to other elements. This is crucial for increasing the durability and reliability of the entire system.

In our daily practice, we see a growing interest in plastic connectors. They are lightweight and corrosion-resistant. They work great in utility water installations. We offer a wide selection of such products, including welded and pressed connectors.

Onninen also recommends threaded connectors with O-ring seals. They guarantee a tight connection without the use of additional sealing agents. This is a convenient and reliable solution, especially in hard-to-reach places.

In the case of gas installations, safety is key. That is why we offer special gas-certified connectors. They meet rigorous standards and provide maximum tightness. These are essential elements in every gas installation.

Selecting the right threaded and soldered fasteners is key to the success of any project.   At Onninen we offer not only a wide range of products, but also expert advice.
