摘要：
An isolation sleeve extends from an adapter into the bore of a tubing head to isolate high pressure frac fluid from the body of the tubing head. The isolation sleeve may be installed by a running tool that can screw the sleeve onto a packoff bushing located within the tubing head. The running tool can also retrieve the isolation sleeve by unscrewing it from the packoff bushing.
