Compression Fitting Detal-met MGZ20X3/4 — PP connector 20 mm x 3/4" (male thread)

Detal-met MGZ20X3/4 is a polypropylene (PP) compression fitting designed to connect a 20 mm plastic pipe to a 3/4" male threaded fitting. The connector creates a mechanical, leak-resistant joint suitable for domestic and light commercial plumbing. It is intended for use with water distribution, heating circuits and routine pipework repairs where a 20 mm pipe must interface with a standard 3/4" threaded valve or adapter.

Advantages

The PP compression design provides corrosion resistance and is compatible with common plastic piping materials, offering a reliable seal without the need for solvent welding or specialized tools. Its compact form factor and male threaded outlet simplify installation to threaded valves or fittings. The component is suitable for potable water systems and heating circuits when installed according to relevant standards.

Suitable for

• Connecting 20 mm plastic pipe to 3/4" threaded valves or adapters
• Domestic water supply and distribution lines
• Heating circuit connections and radiator feeds
• Plumbing repairs and retrofit works

Key specifications

• Material: polypropylene (PP)
• Pipe connection size: 20 mm (compression)
• Thread connection: 3/4" male thread
• Application: potable water and heating systems
• Connection type: mechanical compression joint

How to use

Prepare the 20 mm pipe by cutting squarely and deburring the end to ensure a smooth, clean surface. Slide the compression nut and sealing components onto the pipe according to the manufacturer's orientation, insert the pipe fully into the fitting body, and tighten the compression nut by hand then with an appropriate wrench until a secure, leak-free connection is achieved. Thread the male 3/4" outlet into the mating female thread using suitable sealing tape or gasket as required by the installation context. Follow local plumbing codes and manufacturer torque guidance to avoid over-tightening.

Usage recommendations

Use only with compatible 20 mm plastic pipe types and ensure threads and sealing surfaces are clean before assembly. Verify the fitting is suitable for the system temperature and pressure. When connecting to potable water systems, follow applicable hygiene and installation regulations. Inspect joints after initial pressurization and periodically during service.
