An endoscopic fluid applicator including an outer delivery device having a channel extending therethrough between proximal and distal ends that is defined along its length by an inner diameter, and an inner plunger device with a handle at a proximal end and an elongate plunger element extending outwardly from the handle to a distal end that is defined along its length by an outer diameter and is sized and shaped relative to the outer delivery device channel so as to be receivable therein. The elongate plunger element has a length such that, when received within the outer delivery device channel, it extends at least substantially to the distal end of the outer delivery device. Proximal end portions of the outer delivery device and inner plunger form an interference fit with one another substantially only when the elongate plunger element is fully received within the outer delivery device channel.
