The UniFlex Pro™ liner hanger-packer is the industry’s first integral liner hanger/packer system for cemented liner applications. It is built on a one-piece mandrel with no internal connections for added dependability. External moving parts are rotationally locked to the body, preventing back-off of threaded outer components, even if demanding conditions call for extensive rotation to reach bottom.
