How to choose the right press-fit connectors?

The right choice of press-fit connectors is crucial for a successful installation. At Onninen, we advise on choosing the optimal solutions. We help you consider all the important factors. The most important selection criteria are:

Type of medium   - different connectors are used for water, different for gas. The material must be resistant to the transported substance. Special safety certificates are required for gas installations.

Pipe material   - connectors must be compatible with the pipe material. Other solutions are used for copper, steel or plastic. Incorrect selection may cause leaks or corrosion.

Pipe diameter   - connectors must ideally match the pipe diameter. Too small or too large elements will not ensure tightness. It is worth paying attention to the availability of reductions when changing the cross-section.

Working conditions   - the pressure and temperature of the medium must be taken into account. The connectors must withstand extreme conditions. Special alloys are used in high-temperature installations.

Assembly tools   - different systems require dedicated crimpers. It is worth checking the availability and cost of the necessary equipment. Some brands offer universal solutions.

At Onninen we help you choose the optimal connectors for each project. Our consultants analyze the individual needs of the client. They propose the best technical and economic solutions. We provide comprehensive support at every stage of implementation.

Recently, we advised on the selection of connectors for a large housing estate project. The client needed a solution for domestic water and central heating installations. We suggested the Onnline system due to its excellent price-quality ratio. The connectors proved to be excellent, ensuring trouble-free operation of the installation.

When modernising old installations, we often encounter the challenge of combining different materials. We recently helped to renovate a historic building. It was necessary to connect the existing copper pipes with the new plastic installation. We used special Viega transition connectors. This allowed for the safe integration of the old and new parts of the system.

Pressed connectors guarantee tightness and durability of the installation.   At Onninen we offer comprehensive solutions in this field. We provide top quality products and expert advice. We invite you to contact our specialists. We will help you select the optimal connectors for your project.
