Copper reducing coupling SANHA 5240 35 x 22 mm

The Copper reducing coupling SANHA 5240 35 x 22 mm is a mechanical fitting designed to join copper pipes of different diameters. Manufactured by SANHA, this coupling provides a secure, corrosion-resistant connection for plumbing and heating systems where a reduction from 35 mm to 22 mm copper tube is required. The product is intended for use in domestic and commercial installations and is suitable for both hot and cold water circuits when installed according to applicable standards.

Advantages

This reducing coupling offers dimensional accuracy and a robust mechanical connection that minimizes the risk of leaks when properly installed. Made from copper, the fitting resists corrosion and provides good thermal and electrical conductivity. Its compact design allows installation in confined spaces and facilitates straightforward integration into existing copper pipework without the need for complex adapters.

Suitable for

• Connecting a 35 mm copper pipe to a 22 mm copper pipe
• Domestic hot and cold water distribution systems
• Commercial plumbing and heating installations

Key specifications

• Material: Copper
• Connection sizes: 35 mm to 22 mm
• Type: Reducing coupling (mechanical solder-free fitting)
• Suitable media: Water (hot and cold), compatible with standard potable water systems when installed properly
• Installation environment: Indoor plumbing and heating systems

How to use

Prepare the copper pipes by cutting squarely and cleaning the outer surfaces to remove burrs, oxides, and contaminants. Slide the coupling onto the larger or smaller pipe as required and ensure full insertion to the seat or marking provided on the fitting. Depending on the installation practice and system design, secure the coupling using the manufacturer-recommended method (for example, soldering or approved mechanical joining technique) and verify alignment and support of the adjacent pipework. After assembly, perform a pressure test in accordance with local codes to confirm leak-tightness before placing the system into service.

Usage recommendations

Use compatible cleaning and flux materials if soldering, and follow SANHA installation instructions and local plumbing regulations. Ensure pipe ends are properly prepared and support piping to avoid stress on the joint. For applications outside typical potable water or heating systems, consult technical documentation or a qualified installer.
