Description
What is this Bonfix Alu-Press elbow fitting 25 x 25 mm?
The Bonfix Alu-Press elbow fitting 25 x 25 mm is a brass press fitting (90° elbow) designed for connecting multilayer pipes (Alu-PEX) with an outer diameter of 25 mm. This press elbow allows you to create a precise 90-degree angle in piping systems without bending the pipe.
This elbow fitting is also referred to as a 90 degree press fitting for Alu-PEX or multilayer pipe systems, making it a commonly used solution in both residential and commercial installations.
This makes the fitting ideal for installations where a clean, reliable, and space-saving solution is required in drinking water, heating, and cooling systems.
The fitting is made of high-quality brass and features a stainless steel press sleeve with an EPDM seal. This ensures a durable, leak-free connection that can withstand high pressure and temperature.
This 25x25 mm press elbow fitting is widely used in distribution lines and heating systems where multiple circuits are connected.
Bonfix alu-press fittings are equipped with a Leak Before Pressed (LBP) function, meaning unpressed connections will leak during pressure testing. This allows installers to immediately detect missed connections before the system is put into operation.
Why choose an Alu-Press elbow fitting?
A press elbow (90° fitting) is used when pipes need to change direction at a right angle. Compared to bending, a press fitting offers:
- a precise and clean 90° connection
- reduced risk of pipe damage or kinking
- fast and leak-free installation without soldering
The connection is made using a press tool, creating a permanent and reliable joint.
Features of the Alu-PEX system
The Alu-Press system combines multiple material properties:
- flexibility of plastic (PEX)
- stability of aluminum
- corrosion resistance of brass
This makes alu-press couplings, elbows, and other fittings highly suitable for modern installations.
The fitting is suitable for multilayer pipe 25 × 2.5 mm and is an essential component in complete piping systems.
Applications
This Bonfix 25 mm elbow fitting is used in:
- drinking water installations
- central heating systems
- underfloor heating systems
- cooling installations
- oil-free compressed air systems
Within these systems, the fitting is often combined with other alu-press fittings and couplings to build a complete piping system.
Advantages of this Bonfix press elbow 25 mm
- precise 90° angle connection
- fast installation with press tools
- leak-free and durable connection
- suitable for drinking water and heating
- corrosion-resistant brass
- compatible with multiple press profiles (TH, H and U)
- long service life
Using press fittings significantly reduces the risk of installation errors.
Installation and assembly advice
For proper installation:
- Cut the multilayer pipe straight
- Calibrate and deburr the pipe
- Insert the pipe fully into the fitting
- Press using suitable press tools
- Visually check the connection
Always use a suitable multilayer pipe to ensure optimal and leak-free system performance.

Frequently Asked Questions
What is an Alu-Press elbow fitting?
An Alu-Press elbow fitting is a press fitting used to connect two multilayer pipes (Alu-PEX) at a 90-degree angle. The connection is created using a press tool, resulting in a permanent and leak-free joint. This system is widely used in drinking water, heating, and cooling installations due to its reliability and fast installation. Alu-press elbow fittings are commonly applied in both residential and commercial piping systems where durability and precision are required.
Which pipes are Bonfix Alu-Press elbow fittings suitable for?
Bonfix Alu-Press elbow fittings are designed for multilayer pipes (Alu-PEX) with specific outer diameters such as 16 mm, 20 mm, 25 mm, 26 mm, 32 mm, 40 mm, 50 mm and 63 mm. It is essential that the fitting size exactly matches the pipe diameter to ensure a proper and leak-free connection. Always use a compatible Alu-pex pipe within the same system to avoid installation issues. Using the correct pipe size is crucial for long-term system performance.
What does “Leak Before Pressed” (LBP) mean?
“Leak Before Pressed” (LBP) is a safety feature that ensures a fitting will leak if it has not been pressed. This makes it immediately clear during pressure testing if any connections have been missed. As a result, installation errors can be detected and corrected before the system is put into operation. This significantly reduces the risk of leaks, water damage, and costly repairs.
Do I need special tools for installing a press elbow fitting?
Yes, installing an Alu-Press elbow fitting requires a suitable press tool that matches the system. In addition, a pipe cutter and calibration tool are needed to properly prepare the multilayer pipe. It is important to use compatible press profiles such as TH, H, or U to ensure a secure and durable connection. Using the correct tools guarantees a reliable and long-lasting installation.
What is the difference between a press fitting and a compression fitting?
A press fitting is permanently connected to the pipe using a press tool, while a compression fitting is tightened mechanically. Press fittings offer faster installation, lower risk of leaks, and are maintenance-free. Compression fittings may require periodic checks, whereas press systems are designed for long-term reliability.
Where are Alu-Press elbow fittings used?
Alu-Press elbow fittings are used in drinking water systems, central heating installations, underfloor heating, cooling systems, and utility projects. They are essential for creating directional changes in piping systems while maintaining a reliable connection. These fittings are widely used in both residential and commercial applications where efficiency and durability are required.
Can I bend a multilayer pipe instead of using an elbow fitting?
In some cases, multilayer pipes can be bent using a bending spring, but an elbow fitting often provides a more precise and secure solution. A press elbow ensures a clean 90-degree angle without the risk of kinking or damaging the pipe. This is especially important in fixed installations or visible piping where accuracy matters.
Which other fittings are used together with an elbow fitting?
An elbow fitting is typically combined with straight couplings, T-fittings, reducers, and wall plates to create a complete piping system. By combining different fittings, you can build a flexible and efficient installation. View the full range of Alu-press fittings to find all compatible components for your system.
When do you use a 25 mm Alu-Press elbow fitting?
A 25 mm Alu-Press elbow fitting is commonly used in distribution lines and larger heating systems within residential and light commercial installations. This size is suitable for supplying multiple circuits or zones. It is often applied in main distribution lines where higher capacity is needed. Always use a matching multilayer pipe 25 mm to guarantee a secure and leak-free connection.
