First Model

Fig. This was the first model proposed. Utilizing a thicker "plug" to seal the vessel while also allowing for it to be removed to gain access inside.

Other seal solution ("Plug")

Fig. Closer look at the proposed solution for creating a sealable end. This would use an O-ring for the seal and two screws to hold it in place.

Other Cap Design

Fig. Flat cap that was proposed in order to allow for as much room as possible for other components in pressure vessel.
