Alright, this soft copper tubing is seriously versatile stuff! It's a 5-meter (16.4-foot) coil of pure copper tubing with a 1mm inner diameter and 2mm outer diameter, with 0.5mm wall thickness. The T2 grade copper is high quality with excellent toughness and corrosion resistance - exactly what you need for refrigeration applications. What's great is how flexible it is - you can bend and shape it easily without special tools, making it perfect for creating custom elbows and joints. The heat transfer capabilities are fantastic thanks to that hollow copper structure, which improves efficiency in refrigeration systems. It's commonly used for air conditioners, refrigerators, freezers, and all kinds of cooling systems. But it's also amazing for DIY projects - think architectural models, crafts, gardening applications, or any project where you need small-diameter copper tubing. The 5-meter length gives you plenty to work with for most projects. The copper is soft enough to work with hand tools but durable enough to hold its shape once formed. Whether you're doing professional HVAC work, appliance repair, or creative DIY projects, this copper tubing delivers reliable performance. The quality seems solid - no imperfections or kinks in the coil. Definitely a handy material to keep in your workshop for various projects. Just remember to keep it away from children and allow for small measurement variations since it's manually measured. Great value for the length you get!
