USA Industries' Double Block & Bleed (DBB) pipe plug is built with two separate sealing areas that allow the user to positively isolate upstream gases from internal piping. As a result of this design, it makes performing modifications, repairs and hot work much safer, quicker and easier. The Double Block & Bleed plug also has a vent between the compression seals that lets the user verify the seals' integrity and pressure test the hydrotest welds by positioning the weld between the two seals.
