Everlast 50400H20 is the preferred Lubricant/Sealant of Frac valve owners and renters. 50400H20 is a 100% Synthetic Frac valve Lubricant/Sealant containing NO solids such as Mica, Titanium Dioxide, cheap abrasive Graphite, Molybdenum Disulfide or other fillers. 50400H20 contains Lubchem’s proprietary Extreme Pressure additive package which provides superior protection under the most demanding conditions. Commonly used frac valve lubricants are washed/dissolved out with each job and valves must be dissembled and relubricated after each job. 50400H20 does not wash/dissolve out and valves are only required to be “topped” off before sending out to another job. Simply put, 50400H20 remains in the valve longer providing superior protection of internal metal surfaces of the valve without the harmful solids found in other lubricants.
