Sleeves are produced from rubber sheets. If their height is 1000 mm and lower and the wall strength not smaller than 2 mm, they can be vulcanized using a 45° vulcanization spot.
If the wall strengths are smaller or the heights greater than 1000 mm, they are vulcanized with overlapping joints that are approximately 20 mm wide. Additional sealing is available for uses in which the vulcanization joint is exposed to increased stress.
