ABSTRACT:
A seal for use in large liquid storage tanks having a floating roof and fixed, slotted gauge pole vertically extending through a well with a sliding cover is disclosed, the seal comprising two half sleeve members joined to form a tubular sleeve surrounding the gauge pole within the well of the floating roof, means to join the two half sleeve members together, and a sealing collar and gasket which seals the aperture in the sliding cover and connects the sleeve to the sliding cover of the well. The seal sleeve member extends from above the roof through the well and down into the liquid, thereby closing all the exposed slots on the gauge pole.
