Copper fittings

Copper connectors - essential elements of professional installations

Copper fittings are a key element in modern plumbing and heating systems.   In our daily practice, we see a growing interest in these products. This is due to their reliability and durability. Copper as a material has many advantages. It is resistant to corrosion and bacteria. It also ensures the hygiene of the installation for many years.

We are often asked about the types of copper connectors available. Our offer includes a wide selection of products. They include:

• 90° and 45° elbows
• Single and double cup arches
• Straight and reduction sleeves
• Equal and reducing tees
• Transition connectors for other materials

Each of these elements plays an important role in creating an efficient and tight installation.   Elbows allow you to change the direction of pipes at the right angle. Sleeves are used to connect straight sections. Tees allow you to branch the installation. Adapters allow integration with other systems.

Copper connectors - how to choose the right product?

Choosing the right copper connectors is a key issue. It affects the quality and durability of the entire installation. Our experience shows that it is worth paying attention to several aspects. First, you need to choose the right size. It must match the diameter of the copper pipes used. Second, the type of connection is important. You can choose between soldering or pressing connectors.

For drinking water installations, we recommend using lead-free fittings.   They provide the highest level of safety. For heating installations, resistance to high temperatures is key. It is also worth paying attention to the system's operating pressure. The connectors must be selected for its value.

Many customers ask us about the differences between soldered and pressed connectors. Each solution has its advantages. Soldered connectors provide a very durable connection. However, they require appropriate assembly skills. Pressed connectors are easier and faster to install. They also guarantee high tightness.

Our experience shows that it is worth investing in products from proven brands. This translates into long-term and failure-free operation of the installation. It also reduces the risk of costly repairs in the future.

Copper connectors in practice - application examples

Copper connectors are widely used in various installation projects.   We recently used a wide range of these products in a project for a large office complex. 90° elbows allowed for precise installation along the walls. T-pieces allowed for efficient branching of the system to individual floors.

In the case of modernization of older buildings, we often use transition connectors. They enable the integration of new copper sections with older parts of the installation. Reduction sleeves are useful for connecting pipes of different diameters. This is a common situation in expanded systems.

For underfloor heating installations, we recommend press-in connectors. They provide quick and secure installation. This is particularly important for large surfaces. In the case of utility water installations, socketless connectors work well. They minimize the risk of water stagnation and bacterial growth.

In our daily practice, we see that properly selected copper connectors are the basis for a successful installation. They ensure not only tightness, but also ease of any future modifications.

Copper connectors are products that require professional knowledge when selecting and installing.   At Onninen we offer not only a wide range of products, but also professional advice. Our specialists will help you choose the best solutions for each project. We invite you to contact us and take advantage of our experience in the field of copper installations.
