Gute Isolation, Alufolie empfindlich.
Fits. For a 102mm flexible tube, I took the hose with an inner diameter of 125mm, but you shouldn't choose it any smaller. The outer material is not exactly robust, but otherwise everything is ok. Please correct in the description that the product is also suitable for temperatures above 80C (in my opinion). After all, it is mineral wool, not foam insulation.
