a plug body extending from a top end to a bottom end;
a sealing member positioned at the bottom end of the plug body, the sealing member being composed of an elastomeric material; and
a non-rotating profile positioned at the bottom end of the plug body;
wherein the sealing member protrudes past the non-rotating profile such that the sealing member comes into contact with a surface before the non-rotating profile;
wherein the sealing member is configured to depress against the surface until the sealing member no longer protrudes past the non-rotating profile; and
wherein depression of the sealing member until the sealing member no longer protrudes past the non-rotating profile is required for the non-rotating profile to be engageable with a downhole apparatus.
