Product information

Description

The Perfexim water meter half coupling 3/4" DN20 PN16 model 5120 is a dedicated fitting for installing or replacing a water meter in standard DN20 (3/4") pipelines. Designed to provide a secure threaded and bolted interface, this half coupling fits meters and piping systems rated for PN16 pressure. Its construction supports straightforward integration with residential and light commercial cold water metering systems while maintaining alignment and seal integrity during installation.

Advantages

This half coupling offers a compact and reliable connection point for DN20 water meters, enabling safe and repeatable installations. The product is compatible with commonly used 3/4" meter installations and is built to match PN16 pressure requirements. Its form factor simplifies replacing worn or mismatched fittings without modifying the existing pipeline, and the interface design helps ensure a tight mechanical seal when properly installed.

Suitable for

  • Residential cold water metering systems
  • Light commercial water metering applications
  • Replacement of existing DN20/3/4" fittings
  • Meter installations where a threaded/bolted half coupling is required

Key specifications

  • Connection size: DN20 (3/4") compatible
  • Pressure rating: PN16
  • Type: water meter half coupling for threaded/bolted installation
  • Application: cold water metering
  • Mounting interface: standard meter mounting for DN20 meters

How to use

Position the half coupling in line with the DN20 pipeline and align the meter mounting flange or threaded end with the coupling interface. Ensure mating surfaces are clean and that any required gaskets or seals are correctly placed. Secure the coupling to the pipeline and meter using the appropriate bolts or threaded connections, tightened to the torque values recommended for the pipe and meter manufacturer. After assembly, perform a pressure check to confirm there are no leaks and that the meter is correctly aligned and fixed.

Usage recommendations

Use compatible gaskets and follow the meter and pipeline manufacturer's torque and sealing recommendations. For best results, verify material compatibility with the existing piping and perform a pressure test after installation to ensure leak-free operation.
