This type of copper tubing manufactured by an South African producer of copper products. This specific product is characterized by its "soft drawn" or, more accurately, soft annealed temper. This means the copper has undergone a drawing process and is then heat-treated (annealed) to achieve a soft, ductile, and flexible state.   

Predominantly used in the Air Conditioning and Refrigeration (ACR) industry for refrigerant lines in systems for supermarkets, cold rooms, display fridges, and residential and commercial air conditioners. It's also used for repairs and alterations of these units.
