used to form helix 42 can be textured during the extrusion cycle texturing is preferably accomplished by use of an embossed roller or wrapping roller with a textured tape or cloth the coiled helix material will provide uniform pitch during lay up operation without introducing stresses by careful manufacturing it is possible for the diameter and pitch of the helix material to provide optimum performance at elevated pressures while the preferred embodiment of hose assembly 40 eliminates the need for an outer cord there may be requirements to harden portions of hose assembly 40 in order to install orifices holes and eyelets as required for air or fluid distribution this is preferably achieved by incorporating polyester or epoxy coated fiberglass reinforcements into hose 40 during fabrication these hardened sections also prove useful to bear clamping forces as well as forces encountered during installation and or loading a further problem facing existing hose assemblies resides in the inability to easily attach one end of a hose to a component or to a confronting end of a further hose assembly conventional band clamps 50a and 50b are shown in fig2 a abutting beaded ends 52a and 52b of confronting hose members 52 as well as surrounding end portions of a sleeve 54 overlapping.
