Kroil Original Penetrant 1 gal Liquid Can

Overview

Kroil Original Penetrant is an industrial-strength penetrating oil designed to loosen corroded fasteners, free frozen mechanical components, and displace moisture. Trusted by professional gunsmiths, law enforcement armorers, and military specialists since 1939, its formula is engineered to penetrate the smallest threads and crevices where traditional lubricants fail. Beyond its penetrating capabilities, Kroil cleans and lubricates metal surfaces, helps remove carbon deposits, and provides temporary corrosion protection. This 1-gallon liquid can is suitable for high-volume maintenance, armory operations, or professional workshops. The formula is 50-state VOC compliant and is listed by the NSF Nonfood Compounds Program (Category Code: H2, Registration #165745). Manufactured in the U.S.A., it is safe for use on weapons systems, optics mounts, and precision equipment without damaging metal surfaces.
