Product information

Description

Alkotest MZP20 20x20 PEX Sigma-Li straight connector is designed to join two 20 mm PEX pipes with a push-fit/press-style connection. Intended for use in plumbing and heating installations, the connector creates a compact, linear coupling that supports potable water distribution, underfloor heating manifolds and radiator circuits. The design complies with requirements for PEX systems and allows for quick assembly without complex tools when used with compatible press or crimp fittings.

Advantages

The connector provides a secure, leak-resistant joint that maintains pipe alignment and continuity. Its compact straight design reduces the need for additional fittings and conserves space within installation runs. The Sigma-Li profile is engineered for reliable mechanical connection with standard PEX installation methods, offering consistent performance in both residential and commercial systems.

Suitable for

  • Joining two 20 mm PEX pipes in potable water supply lines
  • Connections within underfloor heating circuits and manifolds
  • Radiator feed and return piping using 20 mm PEX
  • Professional plumbing and DIY PEX installations

Key specifications

  • Connection type: straight 20x20 PEX push-fit/press-style connector
  • Pipe compatibility: PEX pipes with 20 mm nominal diameter
  • Intended media: potable water and heating fluids
  • Typical applications: potable water distribution, underfloor heating, radiator circuits
  • Design: compact linear coupling for in-line joins

How to use

Prepare pipe ends by ensuring they are cut square, deburred and free of dirt or damage. Insert each 20 mm PEX pipe into the connector until fully seated according to the connector's insertion depth marks or stop. Complete the joint using the appropriate press or crimp method specified for Sigma-Li profile connectors and compatible PEX systems. After assembly, check each joint for correct engagement and perform a pressure test of the system in line with local codes and installation best practices.

Usage recommendations

Use this connector with PEX piping and compatible press/crimp tools recommended by the piping system manufacturer. Do not reuse connectors after disassembly. Follow local plumbing regulations and carry out pressure testing and flushing before placing the system into service.
