## Long description

Alkotest MZPZ2012 20x1/2 GZ is a straight coupling fitting designed for PEX Sigma-LI piping systems. It provides a threaded 20 mm to 1/2 inch GZ transition to connect PEX pipes and fixtures or valves with female threaded ports. The fitting is intended for water supply and heating installations in residential and light commercial environments where a compact, inline connection is required.
Advantages
The straight fitting offers a secure threaded connection that simplifies transition between PEX Sigma-LI piping and standard 1/2" female threads. Its compact inline design reduces space requirements in piping runs. The fitting is manufactured for plumbing applications, ensuring compatibility with common water and heating system components and enabling reliable, low-profile joins.
Suitable for
Connecting PEX Sigma-LI piping to radiators, valves, or fixtures with 1/2" female threads
Domestic water distribution systems
Underfloor heating manifolds and heating circuits in light commercial buildings
Tight or confined installation spaces where a straight inline transition is needed
Key specifications
Connection type: straight coupling between 20 mm PEX and 1/2" female threaded port
Compatibility: PEX Sigma-LI piping systems
Function: inline transition for water and heating installations
Typical applications: potable water distribution and low-temperature heating circuits
Form factor: compact straight coupling suitable for tight spaces
How to use
Prepare the PEX Sigma-LI pipe by cutting it squarely and deburring the end. Insert the pipe into the PEX side of the fitting according to the system's recommended joining method (crimp/press/expansion or push-fit as appropriate for the specific fitting variant). Thread the 1/2" female connection onto the male GZ thread and tighten to the torque recommended for the mating component, using appropriate sealing material if required by the installation standard. Ensure alignment is straight to avoid strain on the connection and test the assembly under operating pressure before final insulation or concealment.
Usage recommendations
Use only with compatible PEX Sigma-LI pipe and confirm the joining method matches the fitting type. Verify thread sealing practices for the mating component and follow local plumbing codes for pressure testing and thermal expansion allowances.
