Copper 45° Elbow KAN-therm 18 mm for Plumbing and Heating Installations

The Copper 45° Elbow KAN-therm 18 mm for Plumbing and Heating Installations is a precision-formed copper fitting designed to change the direction of 18 mm copper pipes by 45 degrees. Intended for use in potable water, central heating and HVAC systems, this elbow ensures a compact, low-profile directional change with minimal impact on flow. Its copper construction provides good thermal conductivity and corrosion resistance typical for copper plumbing components, making it suitable for both residential and commercial projects.

Advantages

This 45° elbow offers reliable joint performance and dimensional consistency for 18 mm copper piping systems. Its seamless copper body supports soldered or brazed connections and provides stable mechanical strength under normal operating temperatures and pressures found in plumbing and heating applications. The elbow’s geometry reduces turbulence compared with sharper angles, helping to maintain smoother flow through pipe runs. Its compact form factor simplifies installation in confined spaces and integrates with standard copper pipework.

Suitable for

• Potable water distribution in residential and commercial buildings
• Central heating systems and radiator connections
• HVAC piping and service loops
• Tight spaces where a 45° change of direction is required

Key specifications

• Material: copper
• Angle: 45°
• Nominal pipe diameter: 18 mm
• Connection method: designed for soldering/brazing to copper pipe
• Application: potable water, heating, HVAC systems

How to use

Prepare the 18 mm copper pipe ends by cutting squarely and cleaning the outside surface and the inside of the elbow to remove oxidation and contaminants. Apply appropriate flux compatible with potable water systems if soldering, or follow brazing procedures if specified. Assemble the joint, heat uniformly until the filler metal flows and forms a complete seal, then allow the joint to cool naturally. Ensure the installation complies with local plumbing and heating codes and pressure-test the system after installation to verify leak-free joints.

Usage recommendations

For long-term performance, use jointing materials and procedures appropriate for potable water or heating systems, inspect joints for proper capillary action of solder or filler, and avoid mechanical overstress on the fitting during assembly. When used in heating systems, allow for thermal expansion in the piping layout and secure the elbow with suitable pipe supports to prevent strain at the joint.
