Bonfix Alu-press straight coupling 20x20 mm Brass Press Fitting for PEX-AL-PEX Pipe

Description

What is this Bonfix alu-press fitting?

The Bonfix Alu-press brass straight coupling 20 mm is a straight connector used to join two multilayer pipes (Alu-PEX) with an outer diameter of 20 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 that can withstand high pressure and temperature, making it suitable for long-term use in installation systems.

Why choose an alu-press fitting?

Press fittings are one of the most commonly used connection techniques in modern installation systems. Unlike soldering or compression fittings, the connection is made by permanently pressing the fitting onto the pipe using a press tool.

This results in:

• fast installation
• safe connection
• guaranteed leak-free system

The alu-PEX system combines multiple material properties:

• flexibility of plastic
• strength and shape stability of aluminium
• corrosion resistance of brass

This makes the system highly suitable for modern and durable installations.

• drinking water installations
• central heating systems
• underfloor heating systems
• cooling installations
