Abstract

An inlet/outlet, rotomolded, flexible containment fitting for polyolefin double wall vessels attachable externally to a vessel's outer, sidewall. The molded flexible containment fitting having a corrugated wall portion and circular flanges at each end, one of which is attached to the outside of the containment vessel with the opposite flange having a pipe member extending internally through the fitting a pipe flange attached externally to the inner vessel wall thereby providing compensation for deflection, alignment, expansion and contraction of the inner vessel relative to the external containment vessel while still maintaining a secure fluid conduit through both the inner and outer vessel walls.
