129BB Series High Pressure Multi-Flex Block and Bleed Plugs

Petersen multi-flextm isolation double block & bleed inflatable plug is a revolutionary dual seal plug to allow a positive isolation of toxic or flammable product. The vent between the two seals allows the operator to monitor the seal integrity, vent any product that seeps past the first seal, or introduce an inert gas or water between the seals for a positive isolation. These isolation block and bleed plugs are available for most size, pressure, chemical, and temperature requirements. We look forward to providing plugging systems to meet your specific requirements.
