Abstract: An apparatus for blending materials and dispensing the blended materials generally includes a housing, a tip moveably coupled to the housing for dispensing blended materials from the apparatus, and first and second intake units supported by the body and arranged in a generally Y-configuration. The first intake unit has a mixing tube defining a channel for transporting a first material to the tip, and the second intake unit has a mixing tube defining a channel for transporting a second material to the tip for blending with the first material. The first and second intake units also each include a seal coupled to the mixing tube and configured to wrap around a portion of the tip to thereby seal the channel of the mixing tube against the tip.
