Copper coupling SANHA 5270 18 mm (model 1527018)

Copper coupling SANHA 5270 18 mm is a straight copper pipe connector designed for joining 18 mm plumbing, heating or refrigeration copper pipes. Manufactured by SANHA from copper material, the coupling creates a metallic, corrosion-resistant joint suitable for potable water systems, central heating circuits and refrigeration lines where copper-to-copper connections are required. The part is intended for use in soldered or press-fit copper installations and provides a reliable conductive and sealed connection when installed according to accepted piping practice.

Advantages

The SANHA 5270 coupling offers a compact, single-piece copper construction that ensures good thermal and electrical conductivity and inherent resistance to corrosion. Its 18 mm internal diameter matches standard small-diameter copper pipe sizes, enabling straightforward installation in confined spaces. The product is compatible with conventional soldering and press-fit methods for copper piping, allowing flexibility in installation technique while maintaining a durable metal-to-metal joint suitable for potable water and heating systems.

Suitable for

• Joining 18 mm copper plumbing pipes in potable water installations
• Connecting 18 mm copper pipes in central heating circuits
• Forming copper joints in refrigeration and HVAC lines requiring copper connections
• Repairs and replacements of short sections of 18 mm copper pipework

Key specifications

• Material: Copper
• Type: Straight coupling for joining two pipes
• Nominal pipe diameter: 18 mm
• Suitable connection methods: Soldering (brazing) and press-fit installation for copper tubing
• Typical applications: Potable water, heating circuits, refrigeration/HVAC
• Corrosion resistance: Inherent to copper material

How to use

Prepare both pipe ends by cutting square, deburring and cleaning the outer surfaces. For soldered joints, apply appropriate flux and solder using recommended heat and filler materials for copper plumbing until a continuous metallic joint is achieved. For press-fit installations, ensure the coupling and pipe surfaces are clean and free of damage, then use the correct press tool and jaw size to compress the coupling onto the pipes according to the press-fit system manufacturer's instructions. After joining, inspect the joint visually and perform a pressure test or leak test in accordance with local plumbing codes and standards.

Usage recommendations

Use the SANHA 5270 coupling only with compatible 18 mm copper tubing and follow standard installation procedures for soldered or press-fit copper connections. Verify material compatibility with system fluids, observe local regulations for potable-water and heating installations, and perform appropriate pressure testing after installation.
