When you need a penetrant that will get the job done fast and easy the first time, go with Kroil.
  • ✔️ SUPERIOR PENETRATION WITH SILICONE – The addition of silicone to Kroil results in superior penetration and extra lubrication for stuck parts. This high solvency oil penetrates tight spaces to break the bonds of rust, and provide lubrication at the molecular level.
  • ✔️ SIMPLIFIES REPAIRS, MAGNIFIES MUSCLE – When tackling the toughest nuts and bolts, any additional leverage helps. Kroil with Silicone is designed for use on frozen bearings, slides, gate valves, hinges, chains, and more, and requires less torque to loosen. Now that’s leverage!
  • ✔️ ATTACKS CORROSION, DISPLACES MOISTURE – Corrosion meets its match, as Kroil with Silicone penetrates rust, cleans carbon deposits and lubricates rusty parts. Our silicone lubricant also displaces moisture and protects against humidity and salt water, which makes it perfect for marine, boating and fishing applications.
  • ✔️ MADE IN THE USA WITH GLOBAL PACKAGING – Kroil brand and Kano Laboratories were founded in Chicago, Illinois, USA in 1939 by Thomas J. O’Kane. Now located in Nashville, Tennessee, USA, we take pride in employing American workers to produce the highest quality penetrants right here in the USA.

    Valuable tool. Something everyone needs.

    Valuable tool. Something everyone needs.
    This is something you won’t use every day, but when you need it you’ll wish you had it. It’s the best product for penetrating on the market. It was NOT available in any stores locally. Farm and fleet, tractor supply, ace hardware, Lowe’s, menards, car part stores. If you need something before this arrives try 50/50 acetone and ATF, that works very well. If you’re using this and something won’t come apart, heat the bolt or hardware with a torch, then spray this, a heavy amount, then hit the hardware with a punch and hammer. The heat will draw this oil up into the threads. I heated my stuck oil drain plug with a propane torch for 20-30 seconds in a circular motion, then immediately sprayed this after. It did NOT flame. Use heat then this. Use a drip pan to catch any of this from dripping.
