Description

What is this Bonfix alu-press fitting?

The Bonfix Alu-Press brass straight coupling 32 mm is a press fitting designed to connect two multilayer pipes (PEX-AL-PEX) with an outer diameter of 32 mm. This 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 that can withstand high pressure and temperature.

This 32 mm press coupling is commonly used in larger installations such as apartment buildings, commercial properties and main distribution lines, where higher flow capacity is required compared to smaller pipe sizes.

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:

  • fast installation
  • leak-free connection
  • high reliability

The PEX-AL-PEX system combines:

  • flexibility of plastic
  • dimensional stability of aluminium
  • corrosion resistance of brass

This makes it highly suitable for modern installations in both residential and commercial environments.

Applications

This Bonfix 32 mm press coupling is used in various systems:

  • drinking water systems
  • central heating systems
  • underfloor heating (main supply lines)
  • cooling systems
  • oil-free compressed air systems

The fitting is designed for multilayer pipe 32 × 3.0 mm and is compatible with multiple press profiles.

Advantages of this Bonfix press fitting

  • quick installation using press tools
  • reliable leak-free connection
  • suitable for drinking water and heating systems
  • 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:

  1. Cut the multilayer pipe square using a suitable pipe cutter
  2. Calibrate and deburr the pipe
  3. Insert the pipe fully into the fitting until it reaches the stop
  4. Press the connection using a suitable press tool
  5. Visually check the connection

Suitable press profiles include TH, H and U.

Always use tools and components that are compatible with the selected press system.

Frequently Asked Questions

A 32 mm press coupling is used in systems where high flow capacity is required, such as main pipelines, larger residential buildings and commercial installations.
This fitting is suitable for multilayer pipe 32 × 3.0 mm (PEX-AL-PEX). Using the correct pipe size is essential for a secure and leak-free connection.
The difference lies in capacity and application:
  • 26 mm → medium-sized systems
  • 32 mm → large systems and main pipelines
32 mm is used when higher water flow is required.
Yes, but mainly for main supply lines or connections to manifolds. Smaller pipe sizes are typically used for individual circuits.
This fitting is compatible with multiple press profiles, including:
  • TH
  • H
  • U
Always verify compatibility with your press tool.
Yes, this fitting is suitable for drinking water installations and can be safely used in sanitary systems.
If the pipe is not calibrated or deburred, the sealing ring may be damaged, which can lead to leaks or an unreliable connection.
You should choose 32 mm when:
  • longer pipe runs are required
  • multiple outlets are used simultaneously
  • higher flow capacity is needed
Yes, 32 mm is commonly used as a main distribution pipe in larger systems.
