Used and trusted by pros and experienced DIYers alike since 1939, Kroil quickly loosens rusted nuts and bolts, frees frozen shafts, pulleys, and more. No space is too tight to reach, thanks to Kroil’s ability to penetrate the smallest opening, thread or crevice. Corrosion meets its match, as Kroil removes and prevents rust, cleans and lubricates, and displaces moisture.

"Best grease gun I've owned! Works exactly as described. Zero issues with priming the gun. The locking coupler works fabulously and leaves a free hand to help pump."

Good At What it Does

I learned of Kroil during the 90s when I saw it used in a very specialized application. For my needs Kroil works very well.
