Apparatus for fluid sealing channeled flange connectors or underwater pipe line sections, said flange connectors having inner and outer perimeters and opposing annular faces, each defining a circular face channel, and therebeyond a concentric circle of transverse bolt holes for fastening bolts to engage therein, said apparatus comprising: (a) annular body means defining an inner perimeter, having a greater radius than said flange connectors inner perimeters, for engaging an o-ring sealer adapted to fit in said circular face channels, and defining an outer perimeter adapted to tangentially engage all said bolt holes with said o-ring sealer opposite said flange connectors face channels; (b) tab means unitary with said annular body and projecting radially outward, normal to and in the place thereof, and scored for breaking flush with outer perimeters of said flange connectors; and (c) a thumb piece unitary with said tab means and extending transversely and in the plane thereof for manually grasping and inserting said annular body and o-ring sealer between said face channels and in engagement therewith, and for breaking off with a part of said tab means at said score thereafter.
