A titanium cooling spiral sits inside the tube you draw through. The cooling unit comes in three lengths, and the High is the longest. More surface area and a longer path than the shorter units give the vapour further to travel, so it reaches your lips cooler.

The Tempest 2 ships with the Cooling Unit (Medium), which suits most setups. For dry-herb sessions with no water pipe attached, the High cooling unit adds noticeable comfort, especially on longer runs. If you are running it through a water pipe, the short Cooling Unit (Low) is the better match.

This version has a shorter tab at the end, so it fits the Slim's stem as well as the Tempest 2's. Keep a spare and you can let one cool down while you use the other.

Intended for use with: Tempest 2 Slim.
