Crimped Coupling Perfexim GZ 20 mm x 1/2" (62-731-2015-000) stainless connection

Perfexim crimped coupling GZ 20 mm x 1/2" is a stainless connection designed to join a 20 mm plumbing pipe to a 1/2" threaded fitting. The fitting is supplied as a press-fit (crimped) coupling that creates a sealed, mechanical transition between a smooth pipe end and a threaded fixture. Intended for potable water and heating systems, the coupling is compatible with common metal and multilayer pipes and is suitable for residential and light commercial installations.

Advantages

The crimped coupling provides a durable, leak-resistant joint without the need for soldering or sealants. Its stainless construction resists corrosion and maintains mechanical strength over time. The press-fit design enables consistent connections with appropriate crimping tools, reducing installation time and supporting reliable performance in closed water and heating circuits.

Suitable for

• Connecting 20 mm metal or multilayer pipes to 1/2" threaded valves and fixtures
• Potable water supply lines in apartments and houses
• Heating system branches and radiator connections
• Renovation projects where a mechanical, non-soldered connection is required

Key specifications

• Pipe connection size: 20 mm
• Threaded connection size: 1/2" (female thread to male threaded fixture)
• Material: stainless steel (body and connection components)
• Connection method: crimped (press-fit) coupling
• Application: potable water and heating systems
• Suitable with: compatible metal and multilayer pipes

How to use

Prepare the pipe by cutting squarely and deburring the end. Slide the crimp ring or sleeve onto the pipe, insert the pipe fully into the coupling until it seats against the stop, and ensure the threaded end is engaged with the mating fixture. Use the manufacturer's recommended crimping tool and die set to compress the sleeve evenly according to specified crimp dimensions. After crimping, inspect the joint visually and, if applicable, perform a pressure test to confirm a leak-free connection before putting the system into service.

Usage recommendations

Use compatible crimping tools and follow local plumbing codes. Verify material compatibility with the pipe type and operating temperatures. Avoid using the coupling on damaged pipe ends and confirm thread sealing where required by system design.
