The patent describes a fluid mixer-dispenser for use with two component adhesives including a generally cylindrical body having a pair of adjacent parallel cylindrical bores within which a pair of pistons is slidably mounted. A valve system fluidly seals the end of the bores and comprises three thin circular discs, one of which is a solid rupture disc and the remaining two flanking discs have appropriately shaped cutouts therein to prevent premature rupture due to backpressure when used in an underwater environment and to provide rupture at the appropriate internal pressure due to depression of the pistons. A mixing chamber is provided and includes a plurality of discs having appropriately formed cutouts such that when stacked, form passages for the fluids to flow through.
