Abstract
A foam delivery system includes a pump for delivering a pressurized flow of material to a dispenser through a flexible hose. The hose is encased in a flexible, expansible sheath which contains any material which may leak along the hose. The sheath expands in the region of the leak to accommodate the released material and to indicate the presence of the leak. The system also includes a monitor which senses a leak condition and then terminates the pressurized flow of material.
