Description
What is this Bonfix alu-press fitting?
The Bonfix Alu-Press brass straight coupling 16 mm is a straight connector used to join two multilayer pipes (PEX-AL-PEX) with an outer diameter of 16 mm. This press fitting is widely used in drinking water, heating and cooling systems where a reliable and leak-free connection is required.
The fitting is made of high-quality brass and features a stainless steel press sleeve with an EPDM seal. This ensures a durable connection resistant to high pressure and temperature.
Why choose an alu-press fitting?
Press fittings are one of the most commonly used connection methods in modern installation systems. Unlike soldering or compression fittings, the connection is created by permanently pressing the fitting onto the pipe using a press tool.
This results in a fast, secure and leak-free connection.
The PEX-AL-PEX system combines:
- flexibility of plastic
- dimensional stability of aluminium
- corrosion resistance of brass
This makes it highly suitable for modern installation systems.
Applications
This Bonfix 16 mm press coupling is used in various systems:
- drinking water installations
- central heating systems
- underfloor heating systems
- cooling systems
- oil-free compressed air systems
The fitting is designed for multilayer pipe 16 × 2.0 mm and is compatible with multiple press profiles.
Advantages of this Bonfix press fitting
- fast installation using press tools
- reliable leak-free connection
- suitable for drinking water and heating
- corrosion-resistant brass
- compatible with multiple press profiles
- long service life
The use of press connections significantly reduces the risk of installation errors.
Installation and assembly advice
For correct installation, follow these steps:
- Cut the multilayer pipe square using a suitable pipe cutter
- Calibrate and deburr the pipe
- Insert the pipe fully into the fitting until it reaches the stop
- Press the connection using a suitable press tool
- Visually check the connection
Suitable press profiles for this fitting include TH, H and U.
Always use tools and components that are compatible with the selected press system.

Frequently Asked Questions
Which pipe is compatible with this press fitting?
This Bonfix alu-press fitting is suitable for multilayer pipe with an outer diameter of 16 mm and a wall thickness of 2.0 mm (16 × 2.0 mm).
View our range here: 16 mm multilayer pipe
Which press jaw/profile do I need?
This press fitting is compatible with multiple press profiles, including:
- TH profile
- H profile
- U profile
The required press profile depends on your press tool and installation system. In most multilayer pipe systems, the TH profile is commonly used.
Always check that your press tool is compatible before installation.What does 16 x 16 mm mean?
This means both connections are designed for pipes with an outer diameter of 16 mm (multilayer pipe 16 × 2.0 mm).
Is this fitting suitable for drinking water?
Yes, this Bonfix press fitting is suitable for drinking water installations and complies with relevant standards and certifications.
The fitting is equipped with an EPDM seal, which is suitable for drinking water and heating systems. It can therefore be safely used in:
- drinking water systems
- central heating systems
- underfloor heating
- cooling systems
What is the difference between a press fitting and a compression fitting?
A press fitting is permanently pressed onto the pipe using a press tool, creating a strong and leak-free connection that can withstand high pressure and temperature.
A compression fitting works differently: the pipe is secured using a compression ring and nut. This type of connection is easier to disassemble but more sensitive to installation errors.
Press fittings are widely used in modern systems because they allow faster installation and provide a highly reliable connection.
Do I need to calibrate the pipe before installing a press fitting?
Yes, it is strongly recommended to calibrate and deburr the pipe before installing a press fitting.
Calibrating ensures the pipe is perfectly round again and prevents damage to the sealing ring. This results in a proper fit and a reliable press connection.
Calibrating ensures the pipe is perfectly round again and prevents damage to the sealing ring. This results in a proper fit and a reliable press connection.
What are alu-press fittings used for?
Alu-press fittings are used to connect multilayer pipes in installation systems such as:
- drinking water systems
- central heating
- underfloor heating
- cooling systems
What happens if the fitting is not pressed correctly?
Many press fittings feature an LBP function (Leak Before Press). This means the fitting will leak if it has not been properly pressed.
This helps to quickly detect installation errors and prevents hidden leaks.
