A fluid dispensing device has a spool valve in a dispenser housing with a spool in a spool housing and a spool wall around the spool housing with entrance and an exit openings defined therethrough; an entrance channel in the dispenser housing proximate to the spool wall entrance opening; a force applying element in the entrance channel that applies force against the spool wall with entrance and exit ends with the exit end proximate to the spool wall; a hose adapter fitting with an entrance end extending out from and an exit end extending into the entrance and contacting the force applying element with a flow passage extending through it; and fluid communication through the hose adapter fitting flow passage through the force applying element and into an entrance opening in the spool wall; where the force applying element defines a tortuous path through which fluid must travel.

A dispenser comprises a housing defining at least three feed channels, a spool valve with a spool defining at least three flow passages, a deformable sealing plug in at least two of the feed channels and in sealing orientation with both the housing and the spool, and a nipple in at least the two feed channels of the housing comprising sealing plugs; wherein the spool can reversibly rotate between an open orientation and a closed orientation can dispense two-component form formulations that are free of gaseous blowing agents.
