Copper press coupling SANHA 18 mm 1627018, female x female (ZW x ZW)

The SANHA copper press coupling 18 mm is a female-to-female connector designed for secure, solder-free joining of copper plumbing pipes with an 18 mm nominal diameter. Made from copper, this press coupling provides a corrosion-resistant joint suitable for potable water and heating systems. The product is intended for professional plumbing installations and repair work where a reliable mechanical connection is required without the need for flame-based brazing or soldering.

Advantages

This copper press coupling offers quick, reproducible connections that reduce installation time compared with traditional soldered joints. The press-fitting method creates a durable, leak-resistant seal and minimizes the risk of heat-related damage to surrounding materials. Copper construction provides inherent corrosion resistance and thermal conductivity appropriate for water and heating applications. The female-to-female design allows easy connection of two plain-ended copper pipes with compatible press fittings.

Suitable for

• Joining 18 mm copper pipes in potable water systems
• Connections in central heating and radiator circuits
• Repair and maintenance works in residential and commercial plumbing
• Situations where solder-free, flame-free installation is required

Key specifications

• Material: copper
• Connection type: female x female (ZW x ZW) press coupling
• Nominal pipe diameter: 18 mm
• Application: potable water and heating systems
• Mounting method: press-fit (requires compatible press tool and jaws)

How to use

Prepare the pipes by cutting squarely and deburring the pipe ends to ensure full insertion. Mark insertion depth if required by the installation practice. Position the coupling over the two pipe ends so that each pipe reaches the shoulder inside the fitting. Use a compatible press tool with the correct jaw profile for copper press fittings to make the press connection; follow the press tool manufacturer’s instructions to complete the operation. After pressing, inspect the joint visually and, if appropriate for the system, perform a pressure test to verify leak tightness.

Usage recommendations

Use only approved press tools and jaws designed for copper press fittings and ensure the pipe surfaces are clean and free from damage. Store fittings in a dry environment to avoid contamination. For installations in potable water systems and heating circuits, follow applicable local codes and manufacturer guidance regarding support spacing, expansion allowance, and testing procedures.
