Pillows & Pans contain leaks and absorb drips that are too large for a pad. Drip pans are a great method for catching and holding leaks under machines or hoses, or when you need to respond quickly to a spill. Our oil-only pans have drains for water so that only petroleum-based liquids are captured. Universal pans fill completely. Pillow and pan configurations are similar to drip pans except the pillow can be replaced. Replacement pillows are sold separately.
