Abstract: A vacuum hose-pipe adapter that includes a sidewall bifurcated into two portions, wherein the first portion includes a first distal terminal end defining a distal pipe opening a first portion length separating a first proximal end and the first distal terminal end, and a sidewall inner surface of a frustro-pyramidal shape and enclosed configuration tapering in diameter from the distal pipe opening along the first portion length and the second portion with a second distal terminal end opposing the first distal terminal end and defining a distal hose opening, with a recessed bottom wall, with a sidewall inner surface enclosing and defining a first a first hose diameter, and with a second hose sidewall projecting from the recessed bottom wall, toward the distal hose opening, and enclosing and defining a second hose diameter less than the first hose diameter, thereby allowing fluid to flow therein and between the openings.
