Abstract
A plug assembly arranged in a housing including: a plug, a breaker object, a seat, a shear ring and an assembly retainer. The plug is supported by the seat and the shear ring prevents the seat from moving in an axial direction. The shear ring is arranged such that when a threshold pressure differential is applied to a surface of the plug, the shear ring shears and allows for axial movement of the seat. The assembly retainer provides axial support to the breaker object, seat, or shear ring. A plug assembly arranged in a plug tubular. The plug tubular made of a single continuous piece.
