Crimp Coupling Perfexim GZ 25 mm x 3/4" (model 62-731-2520-000)

Perfexim crimp coupling GZ 25 mm x 3/4" is a press-fit pipe connector designed to join a 25 mm smooth pipe to a 3/4" male threaded fitting. Intended for plumbing and heating installations, the coupling creates a permanent mechanical and leak-resistant connection when installed with a compatible press tool and jaws. The design accommodates potable water systems, heating circuits and general pipework where a transition from press-fit piping to threaded components is required.

Advantages

The crimp coupling offers a compact connection solution that eliminates the need for soldering or threaded adapters between press-fit pipes and threaded fittings. When installed correctly with the appropriate press tool, it provides a reliable seal and mechanical strength suitable for domestic and light commercial plumbing. The metal body ensures dimensional stability and consistent performance over time in typical building system conditions.

Suitable for

• Joining 25 mm press-fit pipes to 3/4" male threaded valves and fittings
• Potable water distribution systems
• Heating circuits including radiators and boilers
• General plumbing repairs and retrofits where a press-to-thread transition is needed

Key specifications

• Connection types: press-fit (25 mm) to male threaded (3/4")
• Material: metal body suitable for plumbing installations
• Intended media: potable water and heating fluids
• Installation method: crimp/press with appropriate tool and jaws
• Operating environment: indoor plumbing and heating systems

How to use

Prepare the pipe end by cutting square and deburring to ensure a smooth surface. Slide the coupling over the 25 mm pipe until fully seated, then position the coupling onto the male 3/4" threaded fitting. Use the recommended press tool and compatible jaws for the coupling profile to apply the specified press force and create the crimped joint. Verify the connection visually and with the system pressure test according to local codes and manufacturer guidance.

Usage recommendations

Use only compatible press tools and jaws rated for the coupling profile. Ensure threads on the male fitting are clean and, where required, use thread sealant or PTFE tape per application and local regulations before assembling. Perform a pressure test after installation and follow applicable plumbing standards for potable water and heating systems.
