Abstract
A dispensing gun has a mix head, a purge rod, an actuator, and a joint. The mix head has two fluid component inlets and a mixing chamber that combines the two fluid components. The purge rod is slidably positioned in the mix head and has a forward position for preventing flow of the two fluid components, and a rearward position for allowing flow of the two fluid components. The purge rod is moved by an actuator which is connected to the purge rod by a joint having a head and a cavity.
