SOLVENT PLUNGER CANS help you quickly and easily moisten cleaning cloths or swabs. Pushing down on the brass pump assembly fills upper pan with a measured amount of liquid for moistening. Surplus liquid drains safely back into reservoir. The perforated pan screen serves as a flame arrester. Top rims have molded edge protectors for smooth, trouble-free moistening. Choose from corrosion resistant, high density polyethylene or rugged 24-gauge steel construction. Steel cans are finished in a tough, chemical resistant powder paint.
