Abstract
An integrated multi-pressure fracking adapter apparatus comprising a cylindrical body for mounting on a wellhead casing head, having an exterior circumference, an interior circumference creating a cylindrical passage perpendicular to the radius, pipe and casing seals within the cylindrical passage, a high pressure mounting surface, a low pressure mounting surface, fasteners for securing to wellhead components, an external sealing surface, and a testing port whereby a user installs an integrated multi-pressure fracking adapter in between a lower pressure casing head and a high-pressure fracking valve assembly, injects packing material, verifies the seals functionality, and begins fracking with high pressure fracking fluids thereby reducing costs of high pressure equipment and manhours involved removing and replacing the low pressure rated well head components with high pressure well head components for fracking then restoring the original components.
