Copper reducing coupling SANHA 5240 22 x 15 mm

Copper reducing coupling SANHA 5240 22 x 15 mm is a mechanical copper fitting designed to join two copper pipes of different diameters. The coupling enables a reliable reduction from 22 mm to 15 mm pipework and is intended for use in water supply, central heating and refrigeration systems where copper components are required. The design provides a compact transition between pipe sizes while maintaining continuity of the copper piping and allowing stable flow characteristics.

Advantages

The SANHA 5240 reducing coupling offers corrosion-resistant copper construction, compact dimensions for space-constrained installations and a secure mechanical joint that preserves pipe alignment. Its straightforward geometry reduces pressure losses at the transition and ensures compatibility with standard copper tube dimensions. The fitting is suitable for repeated use in service environments typical for plumbing and HVAC applications.

Suitable for

• Domestic and commercial potable water distribution
• Central heating systems and radiators
• Refrigeration and chilled water circuits
• Repairs or modifications where a reduction from 22 mm to 15 mm is required

Key specifications

• Material: copper
• Connection type: mechanical reducing coupling for copper tubing
• Nominal sizes: 22 mm to 15 mm
• Suitable media: potable water, heating medium, refrigeration fluids (as per system requirements)
• Operating temperature: compatible with typical plumbing and heating temperature ranges (check system specifications)

How to use

Prepare copper pipe ends by cutting square and deburring the inner and outer edges to ensure proper seating. Slide the coupling onto the larger or smaller pipe end as required and align the pipes to maintain a straight run. Install according to the mechanical coupling method specified for SANHA copper fittings—ensure correct insertion depth and follow any required joining procedure (soldering, brazing or approved mechanical joining technique) compatible with this coupling. After installation, check the joint for alignment and perform a pressure test in accordance with the system's commissioning procedures.

Usage recommendations

Use appropriate personal protective equipment when preparing and joining copper pipework. Verify compatibility of the coupling with the system's operating pressures and temperatures, and follow applicable local plumbing and HVAC standards during installation and testing.
