This Backfill Adapter is for use with the Pressure Relief Valve and the Vacuum Plug to fill an enclosure with an inert gas or to pull an enclosure to vacuum while maintaining a seal!
When screwed onto the PRV, the Backfill Adapter seals to the PRV and pulls opens the valve, creating a sealed path into the enclosure that can be removed without breaking the seal. This allows you to fill the enclosure with an inert gas or to seal an enclosure while maintaining vacuum.
