Product information

Description

Alkotest MZP16 16x16 PEX straight coupling (sigma-li) is a metal/plastic inline connector for 16 mm PEX piping. It is designed to join two sections of PEX pipe in plumbing systems for hot and cold water distribution, repair jobs, or when extending existing runs. The coupling supports a compact, straight connection while maintaining hydraulic continuity and minimizes the need to replace pipe sections during maintenance.

Advantages

The metal/plastic construction combines corrosion resistance with dimensional stability to provide a durable joint. Its 16x16 size is compatible with standard 16 mm PEX pipes, allowing straightforward installation with common tools. The straight design preserves flow characteristics and reduces pressure loss at the connection. The connector is suitable for use in both concealed and exposed installations where a reliable inline coupling is required.

Suitable for

  • Joining two 16 mm PEX pipes in domestic water supply systems
  • Repairing damaged sections of PEX piping
  • Extending existing PEX runs in renovation or new-build projects
  • Use in hot and cold potable water installations where compatible fittings are specified

Key specifications

  • Type: straight coupling for PEX pipe
  • Connection size: 16 mm × 16 mm
  • Material: combined metal and plastic construction for strength and corrosion resistance
  • Application: potable hot and cold water plumbing systems
  • Compatibility: designed for standard 16 mm PEX piping and compatible installation tools

How to use

Prepare the PEX pipes by cutting squarely and deburring the ends. Slide any required compression sleeves or rings onto the pipe if the installation system requires them. Insert each pipe end fully into the coupling until it seats, following the assembly depth guidelines of your installation method. Use the appropriate crimping or clamping tool compatible with the system to secure the connection, and verify the joint with a pressure test before concealing or commissioning the installation.

Usage recommendations

Ensure compatibility between this coupling and the chosen 16 mm PEX system components before installation. Follow local plumbing codes and manufacturer instructions for crimp/clamp techniques, and perform a pressure test of the assembled line to confirm leak-tightness. Store fittings in a dry environment and avoid prolonged exposure to UV light when used in exposed installations.
