Best way to attach connectors to a welded tank

Best way to attach connectors to a welded tank

(OP)
Maybe not the exact subject heading. But anyhow, I am designing an open lid box that will contain a few components, namely a reservoir, and a fluid heat exchanger. The box will need components coming out of the box, but cannot leave any holes or gaps where fluid could escape in case a leak happened at the reservoir or exchanger. I want a couple of quick connects coming out of the box to hook water lines up to but I am not sure how to bring them out of the box without leaving potential leak points. I thought of welding the quick connects directly to the outer box, and I though of using a rubber washer on either side of the box wall where the bulkhead or quick connect would exit, but not sure if this is the most common or best way to approach this. The box is about 15" x 15" by 3" high
