I have two rolls of 4 meters without the nuts for a Mando Gold AC unit. And I have two rolls of 7.50 meters, original Muller, unused. The large size. I installed them a year ago and when I moved in, the pipes turned out to be small, so I changed them to larger ones for the cabinet. The rolls that come with the AC unit are 4 meters, each roll for 150. The 7.50 meter rolls, original Muller, are 40 per meter.
