1. A frangible pressure control plug comprising: a first portion of a body adjacent a first end of the plug;a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in a first condition;a groove in the body interposed between the first portion
1. A frangible pressure control plug comprising: a first portion of a body adjacent a first end of the plug;a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in a first condition;a groove in the body interposed between the first portion and the second portion;a bore within the body passing through the first end and the first portion and inaccessible from the second end; anda hydraulic piston between the first end and the groove;wherein, fluid communication between the bore and the groove is prevented in the first condition and allowed in a second condition. 2. The pressure control plug of claim 1, wherein the second condition occurs at a critical pressure applied to the groove towards the first portion. 3. The pressure control plug of claim 1, wherein the first portion is longitudinally displaced from the second portion in the second condition. 4. The pressure control plug of claim 1, wherein the first end includes a seal preventer. 5. The pressure control plug of claim 4, wherein the seal preventer is a slot in communication with the bore. 6. The pressure control plug of claim 1, wherein the bore longitudinally extends through the first portion and passed a longitudinal position corresponding to the groove. 7. The pressure control plug of claim 1, wherein the body includes a lip protruding from the first portion and the hydraulic piston includes at least one ring abutting the lip. 8. The pressure control plug of claim 7, wherein the at least one ring includes an O-ring. 9. The pressure control plug of claim 8, wherein the at least one ring includes a backup ring interposed between the O-ring and the lip. 10. A frangible pressure control plug comprising: a first portion of a body adjacent a first end of the plug;a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in a first condition;a groove in the body interposed between the first portion and the second portion; and,a bore within the body passing through the first end and the first portion and inaccessible from the second end;wherein, fluid communication between the bore and the groove is prevented in the first condition and allowed in a second condition, and wherein the second portion is threaded and the first portion is not threaded. 11. The pressure control plug of claim 1, wherein the groove circumscribes the plug. 12. The pressure control plug of claim 1, further comprising a fluid passageway formed in the second portion and directed towards the groove. 13. The pressure control plug of claim 12, wherein the fluid passageway is at least one bore passing through the second end and opening towards the groove. 14. The pressure control plug of claim 12, wherein the fluid passageway is at least one slot intersecting an edge of the second portion and opening towards the groove. 15. The pressure control plug of claim 14, wherein the edge of the second portion is threaded. 16. A pressure actuatable tool comprising: a sleeve having a wall, the sleeve having an aperture through the wall;a frangible pressure control plug plugging the aperture and preventing fluid communication between an interior and an exterior of the sleeve in a first condition, and providing fluid communication between the interior and the exterior of the sleeve in a second condition, the plug including:a first portion of a body adjacent a first end of the plug;a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in the first condition;a groove in the body interposed between the first portion and the second portion;a bore passing through the first end and the first portion and inaccessible from the second end; andwherein fluid communication between the longitudinal bore and the groove is prevented in the first condition and allowed in a second condition, and wherein a critical fluid pressure in the interior of the sleeve moves the first portion away from the second portion in the second condition. 17. The pressure actuatable tool of claim 16, wherein the first end of the plug faces an exterior of the sleeve and a second end of the plug faces an interior of the sleeve. 18. The pressure actuatable tool of claim 17, wherein the sleeve includes a passageway that directs fluid pressure from an interior of the sleeve to the groove and towards the first portion. 19. A pressure actuatable tool comprising: a sleeve having a wall, the sleeve having an aperture through the wall;a frangible pressure control plug plugging the aperture and preventing fluid communication between an interior and an exterior of the sleeve in a first condition, and providing fluid communication between the interior and the exterior of the sleeve in a second condition, the plug including:a first portion of a body adjacent a first end of the plug;a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in the first condition;a groove in the body interposed between the first portion and the second portion; and,a bore passing through the first end and the first portion and inaccessible from the second end;wherein fluid communication between the longitudinal bore and the groove is prevented in the first condition and allowed in a second condition and wherein the aperture includes a securement feature for retaining the second portion and not the first portion. 20. The pressure actuatable tool of claim 19, wherein the securement feature is threads, and the second portion includes threads that matingly engage with the threads of the aperture. 21. The pressure actuatable tool of claim 16, further comprising a hydraulic piston surrounding the first portion, the aperture including a port surrounding the first portion. 22. The pressure actuatable tool of claim 16, further comprising a housing surrounding the sleeve, wherein at least one of the plug and the housing includes a seal preventer preventing sealing of the first end of the plug to the housing in the second condition. 23. A method of actuating a tool using a pressure control plug, the plug including a first portion of a body adjacent a first end of the plug, a second portion of the body adjacent a second end of the plug, the second portion attached to the first portion in a first condition, a groove in the body interposed between the first portion and the second portion, and a bore passing through the first end and the first portion and inaccessible from the second end, the method comprising: inserting the plug in an aperture of a sleeve of the tool, with the second end of the plug facing an interior of the sleeve;increasing pressure within the sleeve and directing the pressure to the groove towards the first portion; and,actuating the tool by applying a critical pressure that fractures the first portion from the second portion in the second condition of the plug to provide fluid access from the sleeve to the groove and bore. 24. The method of actuating a tool as claimed in claim 23, further comprising: changing a size of the groove to alter the critical pressure that the second condition will occur. 25. The method of actuating a tool as claimed in claim 23 wherein inserting the plug in the aperture includes threading the second portion into the aperture. 26. The method of actuating a tool as claimed in claim 23, wherein inserting the plug in the aperture further comprises surrounding the first portion with a hydraulic piston.
