Product information

Description

The SiGMA-Li MZR2520 compression reducer fitting for PEX pipes is designed to connect a 25 mm PEX pipe to a 20 mm PEX pipe in potable water and heating systems. This mechanical reducer provides a compact inline transition between two common PEX diameters, enabling reliable flow reduction without the need for soldering or solvent welding. The fitting is intended for domestic and light commercial plumbing where PEX piping and compression connections are specified.

Advantages

The compression design ensures a secure, leak-resistant mechanical joint that can be installed with basic plumbing tools. Its compact form factor minimises space requirements in confined installations. Compatible with standard PEX dimensions, the reducer offers a straightforward way to change pipe sizes while maintaining system integrity and flow performance.

Suitable for

  • Residential potable water distribution with PEX piping
  • Heating circuits and radiator feed lines using PEX
  • Repair or modification of existing PEX networks where diameter reduction is required
  • Light commercial plumbing installations with PEX systems

Key specifications

  • Type: Compression reducer fitting for PEX pipes
  • Material compatibility: PEX piping systems
  • Connection sizes: inlet 25 mm → outlet 20 mm
  • Application: potable water and heating installations
  • Installation: mechanical compression connection, no soldering or solvent required

How to use

Prepare the PEX pipe ends by cutting square and deburring to ensure a clean, straight edge. Slide the compression nut and any supplied olive or ferrule onto the pipe, insert the pipe fully into the fitting until it seats, then hand-tighten the nut and complete the connection with the recommended torque using a wrench. Verify proper alignment and tighten according to manufacturer guidance to achieve a leak-free joint. After assembly, test the system under normal working pressure to confirm there are no leaks.

Usage recommendations

Use with compatible PEX pipe dimensions and follow local plumbing codes. Avoid over-tightening the compression nut to prevent damage to the pipe or fitting. Inspect connections after initial pressure testing and during routine maintenance to ensure continued integrity.
