• Stinger and Packoff Bushing


    The stinger is used together with the packoff bushing. The retrievable packoff bushing is a seal element to provide pressure integrity for setting the liner hanger and during liner cementation.



    • Fully retrievable, leaving full bore liner top and requiring no drill-out time
    • High differential pressure capability
    • Minimizes the pump-out forces exerted on the running string during cementing
    • Locking dogs supported by an inner sleeve and not by the slick stinger
