Compression reducing coupling Comap MultiSkin brass/tinned 20x16

Compression reducing coupling Comap MultiSkin brass/tinned 20x16 is a compact reducer designed to join copper or compatible plastic-sheathed pipes of different diameters in heating, plumbing and potable water systems. The body is made of brass with a tinned finish to enhance corrosion resistance and ensure long-term mechanical stability. The 20x16 size provides a secure transition between a 20 mm and a 16 mm piping run and is compatible with MultiSkin press-fit tools and fittings for a streamlined installation process.

Advantages

The brass construction with tinned surface offers improved protection against oxidation while maintaining dimensional accuracy for a reliable press-fit joint. The coupling’s reduced footprint simplifies installations in confined spaces and supports a leak-tight connection when used with compatible MultiSkin press tools. Its design minimizes the need for soldering or threaded adapters, reducing installation time and potential heat exposure to surrounding materials.

Suitable for

• Joining 20 mm to 16 mm pipe runs in heating circuits
• Domestic potable water distribution systems
• Plumbing repairs and retrofits where diameter reduction is required
• Applications using MultiSkin press-fit tools and compatible fittings

Key specifications

• Material: brass with tinned finish for corrosion resistance
• Connection type: compression / press-fit compatible design
• Size: reducer for 20 mm to 16 mm pipe diameters
• Application areas: heating, plumbing, potable water systems
• Compact form factor suitable for confined installation spaces

How to use

Prepare both pipe ends by ensuring they are cut square, deburred and clean. Slide the compression reducing coupling onto the larger diameter pipe first and then align the smaller pipe section into the opposite end. Use the recommended MultiSkin press-fit tool or compatible pressing equipment to compress the coupling at the factory-specified press points until a secure mechanical joint is achieved. Verify alignment and integrity of the connection and test the system according to applicable pressure and leak-testing procedures before commissioning.

Usage recommendations

Use only with MultiSkin-compatible pressing tools and fittings, and follow the tool manufacturer’s instructions for pressing parameters and jaw selection. Avoid using the coupling with incompatible pipe materials or in systems that exceed the recommended pressure or temperature ratings for the piping system. Perform routine inspections after installation and pressure-test the assembly before putting the system into regular operation.
