I have a set of copper pipes for air conditioners, all unused. There are 3 small ones and the rest are large. The large pipes are for 18,000 BTU air conditioners, except for one roll that is suitable for a 12,000 BTU air conditioner. The size is standard, usually 4 meters per roll, as it comes with the box. Selling all rolls, price is by offer, and offers must be made publicly.
