Copper elbow SANHA 90° 18 mm model 15002A18 for plumbing and HVAC connections

Copper elbow SANHA 90° 18 mm model 15002A18 is a fixed 90-degree copper fitting designed for use in plumbing and HVAC systems where a reliable change of direction is required. Manufactured by SANHA for compatibility with 18 mm copper tubing, the elbow provides a compact and corrosion-resistant joint suitable for potable water, heating and cooling circuits. The fitting’s geometry allows tight routed runs and compact installations while maintaining flow characteristics appropriate for domestic and light commercial systems.

Advantages

This 90° copper elbow offers durable corrosion resistance inherent to copper material, ensuring long service life in water and central heating environments. Its precise dimensions and smooth internal surface reduce flow disturbance and pressure loss compared with improvised bends. Being compatible with standard 18 mm copper tube enables straightforward installation with common joining methods used in plumbing and HVAC work. The compact fixed-angle design simplifies routing in confined spaces and helps maintain clearances required by building installations.

Suitable for

• Potable water supply lines using 18 mm copper tubing
• Central heating and radiator connections in residential and light commercial installations
• Chilled water and cooling circuits where copper piping is specified
• Tight or compact pipe routing where a precise 90° turn is required

Key specifications

• Material: copper
• Angle: fixed 90°
• Nominal tube diameter: 18 mm
• Application: plumbing and HVAC (potable water, heating, cooling)
• Surface: smooth internal bore for reduced flow disturbance

How to use

Select the copper elbow appropriate for 18 mm tubing and prepare tube ends by cutting square, deburring, and cleaning to remove oxides and contaminants. Join the elbow to the tubing using the installation method specified for the system and local regulations (e.g., capillary soldering or approved mechanical joining technique). Ensure proper alignment before completing the joint and allow any solder or sealing compound to cool or cure fully. After installation, inspect joints for correct seating and test the system under working pressure to verify leak-free performance.

Usage recommendations

Use compatible joining materials and follow local plumbing and HVAC codes. When capillary soldering, use flux and solder appropriate for potable water systems and ensure adequate ventilation. For heating systems, verify temperature and pressure ratings of the overall piping assembly. Store fittings in a dry environment to avoid surface contamination prior to installation.
