Description
What is this Bonfix Alu-Press tee fitting 50 mm?
The Bonfix Alu-Press tee fitting 50 mm (50 x 50 x 50 mm) is a brass press fitting designed to create a branch in multilayer pipe systems (Alu-PEX). With this alu-press tee fitting, you can connect three pipes of equal diameter in a reliable and leak-free way.
This 50 mm tee fitting is commonly used in main pipelines and larger installations where high-capacity flow and distribution are required.
This tee fitting is also referred to as a 50 mm Alu-Press tee fitting or multilayer pipe tee fitting, and is widely used in utility buildings and technical installations.
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.
Bonfix alu-press fittings are equipped with a Leak Before Pressed (LBP) function, meaning unpressed connections will leak during pressure testing.
Why choose an Alu-Press tee fitting?
An Alu-Press tee fitting is used to split a pipe into two directions and create branch connections within a piping system.
Compared to other connection methods, press fittings offer:
- fast and efficient installation
- reliable and leak-free connections
- no soldering or threading required
- long-term durability
The 50 mm tee fitting is ideal for distributing large volumes of water or heat in main and transport lines.
Features of the Alu-PEX system
The Alu-Press system combines several material advantages:
- flexibility of plastic (PEX)
- stability of aluminum
- corrosion resistance of brass
This makes alu-press couplings, tee fittings, and other fittings highly suitable for modern installations.
This fitting is suitable for multilayer pipe and is an essential component in complete piping systems. View the full range here: multilayer pipe.
Applications
This Bonfix 50 mm tee fitting is used in:
- drinking water installations
- central heating systems
- large distribution systems
- cooling systems
- utility and technical installations
The 50 mm tee fitting is typically used in main pipelines and transport lines where large capacities are required. It is often combined with other alu-press fittings and couplings to build a complete system.
Advantages of this Bonfix Alu-Press tee fitting 50 mm
- suitable for large piping systems
- ideal for main and transport lines
