A well bore pressure containment device is provided. Operating as a single stripping and containment device compatible with a wide range of tool string and tubing sizes, the containment device may be integrated with rotating pressure control systems, and be used during completion and work over operations. The containment device has a metal spool, and a flexible bladder concentric and interior to the spool. The bladder may be controllably deformed to seal against a tool string passing through the device using pressure exerted by a fluid in the interstitial space between the spool and the bladder.
