Kilfrost from Keystone Lubricants provides lubrication to air tools, but also absorbs air line moisture and lowers its freezing point, helping prevent tool freeze up. The company says the fluid maintains a tight grip on working surfaces because of its high film strength and its ability to function under extreme pressure. The lubricant also locks up moisture, so it is useful year-round in wet or humid conditions to prevent corrosion in equipment. Non-toxic, non-flammable and non-corrosive Kilfrost is made from a semi-synthetic.
