It is heavy-duty polyurethane (PU) hose with a polyester-polyurethane wall and an embedded PVC coated spring steel wire helix (clockwise spiral). The hose keeps its shape even around a sharp bend. The internal bore is moderately smooth minimising friction and the likelihood of a blockage. The hose is abrasion resistant and almost penetration proof. Temperature range of -40°C to +100°C.
