PLUSCO Inc., is a Houston based manufacturer of premium lubricants, sealants, specialty industrial products, greases, degreasers, cleaners, pipe dopes, wireline sealants, wireline sprays, thread compounds, honey oils, valve lubricants, and coatings for oil field use.

PLUSCO has been instrumental in developing a line of environmentally safe products for mining, construction, offshore drilling, manufacturing, oilfield, and refining industries. Contrary to what most people believe, oil field and other large scale operations (which include exploration, drilling and production) do not have to result in damage to an already fragile environment.

PLUSCO has based its primary efforts toward the innovation of products that biodegrade naturally, pose no harm to the environment, are less expensive, and can out-perform current hazardous materials that have been in use.
