Abstract:
A hose assembly (10) consisting of:an extruded, smooth bore tubular inner liner (12) comprising a polymeric fluorocarbon material, a reinforcing layer (14) having gaps extending therethrough disposed about said inner liner (12), an intermediate coating (16) including an fluorocarbon polymeric material for strengthening and connecting said reinforcing layer (14) to said inner liner (12), and characterized by at least one braided outer layer (18) disposed about and continuously in contact with said reinforcing layer (14) resistant to chemical degradation and for increasing the strength and bending properties of said hose assembly (10) and thereby providing a hose assembly (10) which reduces effusion of molecules therethrough.
