The light pipe unit is constructed of a metallic housing having an elongated fiber optic rod contained therein. At the bottom portions of the rod and housing, that is the portions extending into the vessel, is a glass laminate. The glass laminate covering forms a substantially corrosion-proof seal across the entire distal or lower portion of the unit.
