Apparatus for mixing and dispensing at least two liquids, such as organic resins and polyisocyanates which react to form polyurethane foam, having a cylindrical mixing chamber positioned in the front end of a dispensing gun. The mixing chamber has exterior longitudinal gaskets intermediate its inlet ports so that the two liquids cannot migrate around the outside of the cylindrical mixing chamber. These gaskets extend into, and are held by, small passages in the annular shoulder on the interior facing end of the mixing chamber.
