Lasar Chemicals Absorb King DrumTop Pads absorb drips from leaking drum pumps and help keep drum storage areas neat, clean and free of slip hazards due to substances leaking onto the floor.  An inner layer of high-loft, air-filled polypropylene fibers create uniform pockets of air that attract and hold liquids.  Pre-cut bung holes make for easy access to the drum.  Pads can be removed and replaced with pumps and valves installed.  Lasar Chemicals Absorb King DrumTop Pads come in Universal and Oil Only absorbency. Color coding helps you visually identify the right sorbent for your needs.  Gray Universal pads boast versatile absorbency for oils, coolants, solvents and water.   Blue designates Oil Only absorbency for oil and other petroleum based fluids, but not water.  Both will absorb up to 44oz per pad or 8.6 gallons per package!
