Blade-cooled 41 mm cylinder kit. Without sealing. For Velux or the X30 automatic machine.
Attention: For Velux motors, the small slot at the sealing surface to the cylinder must be filled so that it is tight.
The best way to do this is to use the "Wekem 2K Flüsigmetall" liquid metal, which can be found in the 'Tools' category.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
