Triple reducing T-piece PEX-ALU-PEX 20×16×20 chromed fitting, No name

Triple reducing T-piece PEX-ALU-PEX 20×16×20 chromed fitting is a metal-composite branch connector designed for PEX-ALU-PEX pipe systems. It provides a compact connection that reduces from 20 mm to 16 mm and back to 20 mm, allowing smooth transition between pipe diameters in potable water or heating circuits. The chromed finish offers corrosion resistance and a neat appearance where fittings are visible.

Advantages

The fitting combines the mechanical strength of an aluminium-reinforced composite with the flexibility and corrosion resistance of PEX layers, ensuring reliable sealing and long service life in residential plumbing and heating installations. Its reducing T configuration enables branching and size adaptation in a single component, which simplifies installation and reduces the need for additional adapters. The chromed surface improves resistance to surface corrosion and provides easier cleaning in exposed locations.

Suitable for

• Branching potable water distribution lines in residential buildings
• Reducing and connecting pipes in underfloor heating and radiator circuits
• Compact repair work where a 20 mm to 16 mm reduction is required
• Applications requiring a visible, chromed fitting for aesthetic reasons

Key specifications

• Connection layout: reducing T-piece with side branch
• Pipe compatibility: PEX-ALU-PEX composite pipe systems
• Nominal diameters: 20 mm – 16 mm – 20 mm
• Material: PEX layers with aluminium reinforcement and metal-composite body
• Surface: chromed finish for improved surface protection
• Typical use: potable water and heating circuits

How to use

Install the reducing T-piece by preparing pipe ends according to the chosen joining method for PEX-ALU-PEX systems (cut square, deburr and align). Slide or crimp the suitable connection fittings or sleeves over the pipe ends and insert to the full depth specified by the pipe system manufacturer. Ensure horizontal and vertical alignment before finalizing the joint. Verify tightness after press/crimp or mechanical connection by conducting a pressure test following local plumbing codes.

Usage recommendations

Use compatible fittings and tools recommended for PEX-ALU-PEX systems, follow manufacturer instructions for crimping or press connections, and perform a pressure test after installation. Avoid exposing the fitting to continuous direct sunlight and protect from mechanical damage during installation.
