The three basic types of reinforcement are:
Braided reinforcement can be wire, textile and have single or multiple layers.
Spiraled reinforcement on hydraulic hose is typically wire or textile and has four or six layers (plies). Spiral-reinforced hose can typically handle more severe applications with longer impulse service life.
Helical coil reinforcement keeps the hose from collapsing during
suction (vacuum) and tight bending.
