SANHA press reducing coupling 22 x 15 mm, nickel-plated copper

SANHA press reducing coupling 22 x 15 mm, nickel-plated copper is a press-fit fitting designed to join pipes of two different diameters in potable water and heating systems. Manufactured from nickel-plated copper, the coupling provides corrosion resistance and consistent dimensional accuracy for secure press connections. It is intended for use with press tools and compatible press jaws to create permanent, leak-resistant joints in plumbing and HVAC installations.

Advantages

The nickel-plated copper construction offers enhanced corrosion resistance and good mechanical strength while maintaining solder-free installation. The reducing design allows a smooth transition between 22 mm and 15 mm pipes without the need for adapters or additional sealing materials when used with the correct press system. Precision manufacturing ensures consistent press-fit geometry for reliable sealing and reduced rework in professional installations.

Suitable for

• Domestic and commercial potable water distribution
• Central heating and radiator connections
• Plumbing repairs and system modifications where diameter reduction is needed
• HVAC installations requiring permanent press connections

Key specifications

• Material: nickel-plated copper
• Connection type: press-fit reducing coupling
• Nominal diameters: 22 mm to 15 mm
• Application: potable water and heating systems
• Installation method: press tool with compatible press jaws

How to use

Ensure the pipe ends are clean, deburred and cut square. Slide the coupling onto the larger or smaller pipe as required and position it so that the pipe ends reach the internal stop. Use a compatible press tool and appropriate jaws for the coupling profile and material. Apply the press cycle according to the press tool manufacturer's instructions until the fitting is fully compressed and the joint is formed. Verify the connection visually and, if required, perform a pressure test in line with applicable standards before putting the system into service.

Usage recommendations

Use compatible press tools and jaws from the same press system family to ensure correct press geometry. Store fittings dry and protected from mechanical damage. Do not use press fittings on systems containing fluids or gases for which the material is not rated; consult system specifications for compatibility.
