Factory Mutual Approved Safety Plunger Cans are ideal or cleaning with flammable or volatile fluids. They feature brass flame arrestor dasher screens and pump assemblies and comply with OSHA standards. Available in galvanized steel and high density polyethylene for more aggressive solvents. When the dasher plate is pushed down, the safety can dispenses a small amount of liquid to easily moisten sponges or rags without messy or dangerous spills.
