The Original Penetrant since 1939, SILIKROIL, KROIL with Silicone aerosol is an industrial-strength penetrating oil formulated to quickly penetrate deep into small crevices. KROIL attacks rust and corrosion to help loosen frozen or seized metal fasteners such as nuts, bolts, screws, studs, hinges, tools, pulleys, chains or valves with the added benefits of silicone lubrication. Safe on all metals, it is ideal for stuck parts on cars, trucks, ATVs, fleet, farm and agriculture engines and equipment.

Corrosion Meets its Match

  • FAST-ACTING: penetrates small openings, threads and crevices
  • PRO GRADE: trusted by the professionals
  • SIMPLIFIES REPAIRS, MAGNIFIES MUSCLE: gives you all the leverage you need for those stubborn jobs
  • APPLICATIONS: Use on nuts, bolts, studs, screws, pulleys, shafts, valves, chains, tools, bearings, and any corroded threads or seized metal fasteners

Best on the market, out performs everyone else by

a day ago
I've used Kroil since 1995. I've never found anything that performs anywhere close. I've ever managed to convince a British Engineer that its better than anything here or there, he now agrees.

Yes, I recommend this product.

Greatest!

I have been a loyal customer since 1981. This is the king of rusted nuts, bolts and whatever is corroded. The Best.
