Abstract
A floating vapor seal is suspended in a slotted gauge well that extends through a floating roof of a petroleum product storage tank. It has a flexible, product resistant layer that contacts the inside walls of the gauge well near the level of product in the well. The floating roof contacts the product around the gauge well and has a seal between it and the outside of the well.
