Copper reducing coupler SANHA 5240 28 x 15 mm

The SANHA 5240 copper reducing coupler 28 x 15 mm is a precision-engineered fitting for joining copper pipes of different diameters. It is designed to provide a secure mechanical and fluid-tight connection between a 28 mm pipe and a 15 mm pipe in plumbing, heating and refrigeration systems where copper components are specified. The fitting is suitable for potable water and heating circuits, offering reliable joint performance when installed according to accepted plumbing practice.

Advantages

This reducing coupler is manufactured from high-quality copper to ensure good corrosion resistance and thermal conductivity. Its reducing design allows a smooth transition between pipe sizes without the need for complex adapters, saving space and simplifying system layouts. The part is compatible with standard copper pipe joining methods and provides consistent dimensional accuracy for dependable sealing and long service life when correctly installed.

Suitable for

• Domestic and commercial potable water supply lines
• Central heating circuits and radiator connections
• Refrigeration and air-conditioning installations using copper piping
• Repairs and retrofits where a 28 mm pipe must connect to a 15 mm pipe

Key specifications

• Material: copper
• Connection type: reducing coupler for joining two copper pipes
• Sizes: 28 mm to 15 mm
• Application temperature range: suitable for typical potable water and heating system temperatures
• Compatibility: designed for use with standard copper pipes and common joining techniques

How to use

Select the correct pipe ends and prepare them by cutting square and deburring to ensure full contact. Clean pipe surfaces to remove oxides or contaminants before joining. Install the coupler using the appropriate joining method for copper fittings specified by the installer’s standard practice (for example, brazing, soldering, or approved mechanical joining method) and follow relevant local codes and material data. Ensure proper alignment and allow adequate cooling or curing time for the jointing method used before pressurizing the system.

Usage recommendations

Use compatible fluxes and filler materials when soldering or brazing copper to achieve reliable seals. Verify system pressure ratings and temperature limits of connected components and conform to local plumbing and heating standards during installation.
