The heart of the Power Tank system is the SuperFlow regulator. Keep it clean and dry and it will perform flawlessly for you indefinitely. One easy way to keep the elements for your SuperFlow is by protecting it with our regulator cover. This custom fit cover is designed to fit snuggly over the regulator and guard assembly. It features a cinch cord that closes the cover tightly around the neck of the tank keeping out moisture and debris from your SuperFlow.
