Claim:
1. A large diameter, low pressure plug, comprising: a. a nose configured to fit within an inner annulus of a tubular; b. a collar connected to the nose about an outer boundary of the nose, the collar configured to fit within the tubular; c. a plate top connected to the collar opposite the nose; d. a slip bowl disposed proximate the nose about an outer surface of the collar; e. an O-ring disposed proximate the outer surface of the collar intermediate the nose and the slip bowl; f. a slip disposed about an outer surface of the slip bowl in sliding communication with the slip bowl, the nose, slip, and slip bowl configured to selectively position the O-ring to a first position which does not form a seal between the large diameter, low pressure plug and the inner annulus of the tubular into which the large diameter, low pressure plug is positioned and to a second position which does form a seal between the large diameter, low pressure plug and the inner annulus of the tubular into which the large diameter, low pressure plug is positioned; g. a bottom ramp disposed about the outer surface of the collar proximate the plate top; h. a top ramp disposed about the outer surface of the collar intermediate the plate top and the bottom ramp, the top ramp in communication with the bottom ramp; i. a slip pusher disposed at least partially intermediate the bottom ramp and the slip about the outer surface of the collar, the slip pusher in communication with the slip; and j. a bolt setter in communication with the outer surface of the slip bowl, the bolt setter configured to provide axial movement to at least one of the bottom ramp and the top ramp.
