Double Seal Purge System

B&B Pipe and Industrial Tools offers the Silicone Double Seal Purge System that has been designed to further reduce both inert gas use and purging time. These systems use hi temp silicon discs to form an air tight seal reducing purge times and gas usage for maximum efficiency and reduced production cost. All B&B purge systems are designed to save the pipe fabricator time and money and the Double Seal Purge System is no exception. Real savings will be realized when using this system.

How it Works: Create a seal, fill the chamber with inert gas, monitor oxygen content, weld.
