$145.49
Kroil Original Penetrant Oil in 1-gallon size is a time-tested penetrating oil that belongs in any shooter's or mechanic's toolkit. Since 1939, Kroil has earned its reputation as the go-to solution for breaking down corrosion and freeing stuck fasteners, frozen mechanisms, and seized parts. Whether you're working on firearms, hunting rifles, or general equipment maintenance, Kroil cuts through rust and corrosion where other products fall short.
The formula works by penetrating into the tightest spaces—threads, crevices, and narrow gaps that standard lubricants can't reach. This makes it especially valuable for firearms maintenance, where rust prevention and component mobility are critical to reliability and safety. Kroil not only loosens corroded parts but also cleans, lubricates, and displaces moisture, giving you multiple benefits in one product. The gallon size is ideal for the serious shooter or workshop that goes through penetrant regularly.
Kroil is NSF Nonfood Compounds Program Listed (Category H2, Registration #165745) and meets 50-State VOC compliance standards. It's manufactured in the U.S.A., supporting domestic production. Keep a gallon on hand for routine firearms cleaning and maintenance, rust removal, and any situation where corrosion and seized components threaten your gear's function.
