Brass soldered tee Comap MultiSkin 20x3/4x20 for plumbing connections

The Brass soldered tee Comap MultiSkin 20x3/4x20 for plumbing connections is a three-way fitting made from tinned brass intended for soldered joints in potable water and heating systems. The fitting connects two 20 mm lines with a central 3/4" branch, providing a compact junction element for distributing flow or creating branch lines in copper or compatible multilayer pipe systems. Tinning on the brass surface improves solderability and corrosion resistance, resulting in reliable, leak-resistant connections when correctly installed by soldering.

Advantages

This Comap MultiSkin tee offers a combination of brass strength and tinning for improved solderability, enabling durable joints in domestic and commercial plumbing. The tee’s geometry allows straightforward alignment of pipes and a compact footprint in confined installation spaces. Designed for installations with potable water and heating circuits, it supports stable hydraulic performance and reduces the need for additional sealing materials when properly soldered.

Suitable for

• Distribution branches in domestic hot and cold water systems
• Branching in central heating and radiator circuits
• Connecting 20 mm pipelines to a 3/4" threaded or nominal branch in mixed-material assemblies
• Use in renovation projects where soldered copper or compatible multilayer pipes are present

Key specifications

• Material: Brass with tinning for solderability
• Connection type: Soldered joints for copper or compatible multilayer pipes
• Sizes: Two ends 20 mm, one branch 3/4" nominal diameter
• Applications: Potable water and heating systems
• Configuration: T-piece (three-way junction)

How to use

Prepare pipe ends by cutting square and cleaning to bright metal where the joint will be made. Apply appropriate flux for soldered brass-copper connections and insert the pipes fully into the tee. Heat the joint evenly with a suitable torch until the solder flows and creates a continuous fillet around each connection. Allow assemblies to cool naturally, then remove flux residues and inspect joints for full penetration and absence of gaps. Follow applicable local plumbing codes and safety procedures during installation.

Usage recommendations

Use qualified personnel for soldered connections and verify material compatibility between the tee and the pipes. Ensure the selected solder and flux are suitable for potable water installations if used on drinking water systems. After installation, perform pressure testing according to relevant standards to confirm leak-free performance before commissioning.
