Fan-cooled 41 mm cylinder kit. Without sealing. For Velux or the X30 automatic unit.
Note: For Velux motors, the small slot at the sealing surface where it meets the cylinder must be filled with liquid metal to ensure a tight seal.
It is best to use the liquid metal “Wekem 2K Liquid Metal,” which can be found in the “Tools” category.
A good, affordable standard replacement part. GPO – GOOD PARTS ONLY.
