I have two rolls of 4 meters without the nuts for a Mando Gold AC.
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 and I changed them to larger ones for the cabinet.
The rolls that come with the AC are 4 meters, each roll for 100.
The rolls are 7.50 Muller original, meter for 30.
