Turn your pipe or tube into a heat sink. A hinged design makes these heat sinks simple to wrap around an existing line—no need to cut into your line and drain the liquid to install a heat sink. Multiple fins create a large surface to draw heat away quickly. As they cool down the contents of your line, they heat the space around the heat sink, similar to how radiant heat works.

Secure them together with the included fasteners. You don't need to worry about using heat transfer compounds or putty with these.

Cooling capacity is based on 180° F water flowing through your line at one gallon per minute in a space with an ambient temperature of 65° F and normal airflow.
