The updated datasheet can be downloaded here.
As of Q1 2021 Manuli Hydraulics are able to offer Astro/2 hose with a smooth cover in sizes DN6, 8, 10, 12 and 16.
These new hoses (part number H09074xxx) will replace the current wrapped cover hoses for this product family.
Each specific bore size of the smooth and wrapped cover hoses have identical dimensions, materials and physical characteristics, with the only difference being the aesthetic appearance. As such, the performance of each hose is identical to the originals and the layline information for each will also be the same.
The larger sizes, DN 19, 25 and 31, will remain in the standard wrapped cover form with part numbers H09045xxx.
