New Pig Blue Oil Absorbent Sock, the heaviest sock we make features extra-dense construction to hug floors and stay in place while containing spills. Fine-grade vermiculite filler quickly absorbs leaks, drips and spills; great for spill response or absorbing machine leaks. Stitch-bonded, polypropylene skin resists bursting; reduces dust and holds in liquid, even when saturated. Absorbs and retains oils, coolants, solvents and water. Ideal for dicing and damming liquids. Small 1. 5-inches diameter is great to fit into tight spaces to absorb machine leaks and for special application dicing.
