Locks In Fluids - SpillLock technology absorbs the water-based fluids and holds them inside the sock to prevent drips and leaching. Universal - Spilfyter premium socks absorb both petroleum and waterbased liquids making them the ideal general-purpose absorbent sock. Not recommended for aggressive fluids.
