Compound applicator

A compound applicator comprising:

• a nozzle assembly including a nozzle opening and a plug movable relative to the nozzle opening between a first position in which the nozzle assembly is in a closed state, and a second position in which the nozzle assembly is in an open state;
• a spring configured to bias the plug into the first position;
• a cylinder configured to receive and store a compound material;
• a main housing coupled to the cylinder;
• a handle coupled to the main housing and rotatable relative to the main housing;
• a pull rod having a first end coupled with the plug;
• and
• an input mechanism located at least partially within the handle and/or the main housing and configured to convert rotational motion of the handle into axial movement of the pull rod, thereby moving the plug from the first position toward the second position,
• wherein the spring pulls the pull rod such that the pull rod is biased into tension.
