Methods and systems for fracing

A downhole tool comprising:

• a coupling device configured to couple an object with the downhole tool by inserting the coupling device into the downhole tool and the object;
• and
• a seat within the downhole tool, wherein the object is configured to sit on the seat to isolate a first area from a second area while the object is being run in hole and while the object is coupled with the downhole tool via the coupling device, wherein the object is configured to move in a first, downhole direction by applying pressure against the object, thereby maintaining the seal across the seat by forcing the object across the seat during and after the movement due to the applied pressure, wherein flowing fluid in a second, uphole direction after the movement of the object in the first direction disengages the object from the seat and moves the object such that the object can no longer seal on the seat, wherein the object is not radially positioned within the downhole tool after the object moves in the uphole direction.
