Apollo A7L space suit oxygen vent pad assembly, measuring 5.25″ x 1.25″ x 1″, engraved on the edge with part numbers, "PN-A7LB-109011-01, PN-2895, SN-1004." Manufactured by Air-Lock, the red anodized vent was mounted inside the suit and attached to the back of the neck ring. This vent has a rubber seal that mated with the base of the vent pad on the pressure helmet once fastened onto the suit. This directed the 6.0 cubic feet of oxygen flow from the suit vent system into the pressure helmet which then carried the flow of air into the suit. In fine condition, with some scuffing to the metal.
