The STOPPLE® Train plugging system utilizes proven TDW STOPPLE® technology to provide the safety of inserting two plugging heads through a single fitting. The void between the two plugging heads can be bled down to provide a “zero energy” zone. The sealing element on the secondary plugging head provides double block features at pressures ranging from 0 psi to 1480 psi (current design).
