Abstract: The present disclosure relates generally to loose fill insulation installation systems, for example, suitable for installing loose fill insulation to an installation site. The present disclosure relates more particularly to a loose fill insulation hose including a plurality of tubular sections coupled together so as to form a conduit configured to convey loose fill insulation along a path from a blowing machine to an installation site. The tubular sections include a first hose section, a first connector section, and a second connector section. The first hose section includes a flexible body that forms an opening with a first cross-sectional area. The first connector section includes a plurality of projections that extend inward. The second connector section includes a constricted opening with a second cross-sectional area that is no more than 50% of the first cross-sectional area.
