## Long description

SiGMA-Li MP2034 is a connector coupling with a half-union 20x3/4" designed to join a 20 mm pipe to a 3/4" threaded inlet. It creates a compact mechanical joint suitable for water supply and general plumbing tasks, enabling repairs, retrofits and new installations where a transition between metric and imperial connections is required.
Advantages
The coupling provides a reliable mechanical connection between a 20 mm pipe and a 3/4" threaded fitting without the need for extensive adapters. Its half-union design simplifies assembly and disassembly for maintenance or replacement. The compact form factor saves space in tight installation locations and supports standard plumbing workflows for potable water systems and general-purpose piping.
Suitable for
 Connecting 20 mm pipes to 3/4" threaded valves or fittings
 Plumbing repairs and retrofit projects
 Water supply lines in residential and light commercial installations
 Situations requiring a compact transition between metric and imperial connections
Key specifications
 Connection sizes: 20 mm on one side, 3/4" threaded inlet on the other
 Type: connector coupling with half-union (half-screw fitting)
 Intended medium: water supply and general plumbing
 Form factor: compact mechanical joint suitable for confined spaces
How to use
Prepare pipe ends and threaded fitting by cleaning and removing burrs. Fit the 20 mm pipe into the coupling side designed for the pipe, securing it according to the pipe material and joint method used (for example push-fit, compression or soldering where applicable). Thread the 3/4" half-union into the mating threaded inlet and tighten to the required torque, using appropriate sealing (thread tape or sealant) if the installation method requires it. Confirm alignment and check for leaks under normal operating pressure after installation.
Usage recommendations
Use compatible sealing materials on threaded connections and follow local plumbing codes. Do not apply excessive torque when tightening the half-union to avoid damaging threads. Inspect joints after the first pressure cycle and periodically during routine maintenance.
