Copper coupling SANHA 5270 28 mm (model 1527028) for copper pipe connection

Copper coupling SANHA 5270 28 mm is a straight copper fitting designed to join two sections of 28 mm copper pipe in plumbing and heating systems. The fitting provides a metal-to-metal connection intended for durable, corrosion-resistant service in potable water installations, central heating circuits and general copper-pipe joining tasks. Manufactured by SANHA, the coupling is suitable where a reliable, compact straight join between copper tubes is required.

Advantages

The coupling offers a solid copper construction that ensures compatibility with copper pipe materials and provides good thermal and electrical conductivity. Its straight design enables a compact inline connection that minimizes flow disruption and pressure loss. The product is suitable for potable water and heating applications and resists common corrosion patterns associated with dissimilar-material fittings when used with copper pipework. Installation does not require complex tools beyond standard plumbing equipment for soldering or capillary connection methods.

Suitable for

• Joining 28 mm copper pipes in potable water supply systems
• Connections in central heating and radiator circuits
• General copper pipe repairs and extensions
• Projects requiring metal-to-metal copper joins with minimal flow restriction

Key specifications

• Material: Copper
• Type: Straight coupling
• Nominal pipe diameter: 28 mm
• Suitable media: Potable water, heating fluids
• Application: Plumbing and heating pipe joining

How to use

Prepare the copper pipes by cutting squarely and deburring the ends to ensure full insertion. Clean the pipe ends and the inside of the coupling with appropriate cleaners to remove oxides and contaminants. Fit the coupling onto the pipe ends, ensuring correct alignment and full engagement. Complete the joint using the recommended joining method for copper couplings (soldering/capillary brazing or other approved technique) following applicable local codes and material supplier guidance. After joining, inspect the joint for proper penetration and test the system under pressure to verify leak-tightness.

Usage recommendations

Use compatible cleaning and flux products intended for copper plumbing, and ensure heating or soldering is performed by qualified personnel following safety and building code requirements. Avoid mixing dissimilar metals directly with this copper coupling without appropriate dielectric fittings to prevent galvanic corrosion. Perform pressure testing after installation according to system specifications.
