Abstract
A lipless tubular oil seal assembly uses a tubular type of seal. The new seals create only enough pressure against the casing to provide an adequate seal under most conditions and the small amount of oil that would leak by on the roughest well casing surfaces acts as a lubricant. The new seal has no lip so it cannot turn under and get stuck in the well casing like a cup seal, even under the roughest conditions.
