The Novagard Versilube G351 is a 5.3 oz. tube of silicone grease compound that provides lubrication, long-term aging stability, and radiation resistance for use in nuclear power plants and in closed environments and areas with long service intervals such as refrigerators, vacuum cleaners, and electric regions. The compound is a soap-thickened, dimethyl-diphenyl polysiloxane-based grease. It has a temperature range of -40 to +400 degrees F (-40 to +204 degrees C). It meets United States Military Specification MIL-L-15719A. The compound has an off-white or tan color and a paste consistency.

Industrial lubricants can be found in most machinery performing one or more functions, including reducing friction and wear, preventing components from adhering to each other, distributing loads more evenly, dispersing heat away from moving parts, and preventing corrosion. Although many materials are used as lubricants, the most common are oil (also called fluid lubricants) and grease because of their versatility. Oil lubricants contain either a petroleum or synthetic base, the properties of which are modified by the addition of various additives. Grease lubricants, a mixture of oil lubricant and a thickening agent, have a thicker consistency than oil, enabling use wherever liquids cannot be retained and requiring less frequent changes.

Novagard Solutions manufactures industrial adhesives, sealants, and lubricants. The company, founded in 1977, is headquartered in Cleveland, OH.
