The Oxygen sealer is a machine added by Galacticraft. Its purpose is to seal and pressurize an enclose area so the player may breathe without breathing equipment.


First get an Oxygen Collector up and running, then connect it to the right side of an oxygen sealer (all pipes through walls must use sealable pipes to keep the room sealed) and place a battery in the sealer or supply it with energy on the right side, then right click the sealer and click enable seal, the area must be closed off with an Airlock doorway for the oxygen to seal.

Torches Will Not provide Light in a airlocked Room/Area.
