Designed to pull from the side of the kettle instead of the middle. This helps reduce trub from entering your fermenter. By adjusting the height you can also control how much wort you leave behind in the kettle. Has a 1/2 inch MPT fitting on the end, that screws into the inside coupler of our Heavy Duty kettles. Will only work if your kettle has a 1/2 inch FPT coupler on the inside of the kettle.
