Tundish Inserts are cost effective, temporary containment solutions for leaky valves and equipment. The Tundish insert is prefabricated with smart fabric and is simply placed under leaky valves or equipment that is prone to leaks or blowback. The Tundish insert features an oil immobilizing shell sewn into a bucket shape with a layer of oil absorbent fabric in the bottom. The water-permeable and oil-proof bucket can be placed virtually anywhere. Once the Tundish insert is filled, the oil can be drained and the insert disposed of following required corporate oil waste management guidelines.
