The Oil & Fuel Absorbent Sock has knitted skin which allows liquids to be absorbed faster and more efficiently. The ultra-absorbent filling will retain the liquid it has absorbed. Knitted cover means this sock has the ability to expand, which means that a 1.2 metre sock will absorb up to 4.5 litres and a 3.0 metre sock will up to a massive 11.25 Litres. This is much more than other socks on the market, giving suberb value for money. These ‘hydrophobic’ (water repellent) Oil & Fuel absorbent products are designed to absorb oils, fuels, solvents and most petrochemicals from land and water, as they repel water while readily absorbing all oils and fuels. They will float even when fully saturated with oil, making them ideal for spills on waterways and marine areas.
