Flame proof sealing mechanism

A device for sealing gaps between a substantially planar barrier plate and a conduit passing there through, comprising:

• a section of said barrier plate having a circular opening formed therein, such opening having a circular wall extending perpendicularly therefrom that includes radially inwardly projecting tabs;
• a grommet component having a planar first engaging surface and a circular second engaging surface wherein said first and second engaging surfaces are perpendicular to one another, configured and dimensioned for unobstructed insertion into said opening in said section of barrier plate while in a first rotational orientation and having formed on its periphery circumferentially oriented grooves for receiving said tabs after insertion of said grommet component into said opening and rotation thereof to a second rotational orientation so as to bring both said first engaging surface into direct contact with said planar barrier plate and said second engaging surface into direct contact with said circular wall to form a seal and further having a perforation formed therein for receiving there through said conduit, whereby insertion and rotation of said grommet component locks said grommet component in place to form a seal between said barrier plate and said conduit inserted through said perforation.
