A fluid dispensing device comprising: (a) a spool valve within a dispenser housing, the spool valve comprising a spool within a spool housing, the spool housing comprising a spool wall around the spool housing with at least one entrance opening and at least one exit opening defined through the spool wall; (b) an entrance channel in the dispenser housing proximate to the entrance opening in the spool wall; (c) a force applying element within the entrance channel, where the force applying element applies force against the spool wall around the entrance opening, the force applying element being generally cylindrical with opposing entrance and exit ends with the exit end most proximate to the spool wall; and (d) a hose adapter fitting that has opposing entrance and exit ends, where the entrance end extends out from the dispenser housing and the exit end extends into the entrance channel and is in contact with the force applying element, wherein the hose adapter fitting defines a flow passage extending through it from entrance end to exit end; and wherein there is fluid communication all the way through the flow passage of the hose adapter fitting into and through the force applying element and into an entrance opening in the spool wall; and wherein the force applying element defines a tortuous flow path through which fluid must travel to go through the force applying element from entrance end through exit end; characterized in that the hose adapter fitting applies force to the spool wall through the force applying element such that the spool wall deflects against the spool when the force is applied, or at least one entrance opening through the spool wall has a nib around it that protrudes towards and contacts the force applying element and against which the force applying element applies force to the spool wall.
