## Long description

Reducing coupling 32x20 PEX Sigma-LI MZR3220 is a compact press-fit fitting designed to connect a 32 mm PEX pipe to a 20 mm PEX pipe. It is intended for potable water and heating circuits where a reliable, sealed transition between different pipe diameters is required. The fitting is compatible with press-fit PEX installation systems and provides a space-efficient solution for downgrading pipe size without soldering or threaded joints.
Advantages
The coupling offers a secure, leak-resistant connection using press-fit technology, which reduces installation time compared with adhesive or soldered joints. Its compact design minimizes space requirements and simplifies routing in tight installations. The fitting is suitable for repeated pressure and thermal cycles typical of domestic water and heating systems and is manufactured to provide consistent fit with standard PEX pipe dimensions.
Suitable for
Transitioning from 32 mm to 20 mm PEX piping in potable water systems
Reducing pipe diameter in residential and commercial heating circuits
Installations where a compact press-fit connection is required
Retrofit work where existing larger pipework must connect to smaller PEX lines
Key specifications
Material type: press-fit PEX compatible fitting
Connection sizes: 32 mm to 20 mm nominal PEX pipe diameters
Application: potable water and heating circuits
Joint method: press-fit sealing for mechanical retention and fluid tightness
Design: compact inline reducer for space-efficient installations
How to use
Select matching PEX pipe sizes and prepare pipe ends by cutting square and deburring according to PEX manufacturer recommendations. Insert the 32 mm and 20 mm pipe ends fully into the respective sides of the coupling until the stop. Use the appropriate press tool and jaws designed for press-fit PEX fittings to compress the fitting at the specified press zones, following the tool manufacturer's instructions. After pressing, verify the connection visually and by pressure testing the installation in accordance with local plumbing codes.
Usage recommendations
Use approved PEX pipe and compatible press-fit tools and jaws. Follow local regulations for potable water and heating system installations, perform pressure tests after assembly, and avoid exposure of the fitting to direct UV for prolonged periods. For best results, follow pipe manufacturer guidelines for insertion depth and support spacing.
