During chilling the wort, installing a dip tube to an inline chiller makes it easier to achieve the necessary temperature to inhibit bacterial contaminants' growth. Moreover, cooling of the wort is also required to avoid dimethyl sulfide (DMS) compounds that can produce an off flavour in the beer similar to canned corn.
Brew pot dip tubes do not need to be soldered to the coupler as any leaks will go back to the kettle instead of wasted. Here at Ontario Beer Kegs, we have a wide variety of dip tubes and pickup tubes, so there is sure to be one to work with your brew pot.
Do you have a used keg that needs some upgrades? We also have Stainless Steel liquid and gas dip tubes for use in your corny keg. They don't rust and will not react to your homebrew or wine.
