Blacktop Plunger Cans help you quickly and easily moisten cleaning cloths or swabs. New “smart pump” mechanism helps streamline your swabbing operations. Made of chemically resistant Ryton® and brass, the pump base is designed to leave less liquid in the bottom before having to refill. Pushing down on the pump assembly fills the upper pan with liquid. 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, lead-free, chemical-resistant powder paint in either red or yellow and are backed by an industry exclusive Ten-Year Limited Warranty. FM approved.
