How a Bulkhead Union Works

A bulkhead union allows tubing to pass through a solid surface such as a fridge wall, cabinet panel, or equipment housing while keeping both sides of the connection secure. The threaded section passes through the panel and is tightened with a locking nut, creating a stable mounting point for the push-fit tubing connections.
