Exactly, the claims simply do not make sense. E.g. the ends are designed as standard HW100 ends and as such the part of the cylinder internally that the o-ring sits on is 30mm. The OD of the tube is 37mm. So 37mm - 30mm = 7mm. Divide that by 2 for the wall thickness = 3.5mm MAXIMUM. So the wall thickness cannot be 4.3mm at it's thinnest part.
