FinalSTOPP™
New High Temperature, Metal-to-Metal Line Plugging Technology Meets Industry Requirements
The FinalSTOPP™ plugging system achieves true "double block and bleed" functionality by sealing both upstream and downstream from the fitting, thus permitting pressure inside the fitting to be bled out. In contrast to current technology, the FinalSTOPP seal is obtained in a cavity around the pipe OD on fabricated and precision-machined surfaces.
