No-Tox Food Grade Chain Lubricant, commonly known as No-Tox Chain Lubricant 550, is suitable for most chain lubrication requirements found in the “clean” industries such as food, beverage, pharmaceutical and personal care products. It is NSF H1 registered for use in applications where incidental food contact may occur. No-Tox Food Grade Chain Lubricant coats and penetrates to lubricate the sprockets, links, pins and bushings to reduce friction and wear, and is fortified with rust and corrosion inhibitors for added chain protection.
