High temperature silicon tubing is the perfect tubing to use when dealing with hot wort. It is more inert than standard plastic tubing. This tubing will not melt at boiling temperatures and is safe for use with pumps, or just to drain your hot wort from the boil kettle. This tubing has an inner diameter of 3/8" and can be used with pumps or fittings of equivalent size. It is practically required for larger brewing systems using pumps.
