Food Grade Stainless Steel. Temperature Control Coiled Lid with Gasket. This is our standard 4" threaded lid, and comes complete with gasket. The length of the coils from the bottom of the lid is approximately 18 1/4".  

This Coiled Lid will cool the 13.5g Gallon Conicals.

This Kit contains The Coiled Lid, Connectors, 10 Feet of Tubing and 4 Thumb Clamps.   

An InkBird Temperature Control Unit will automate your Temperature Control and allow you set temperatures through Wifi. 

We are also in the process of having NeoPrene Sleeves for the Fermenters!!! These will greatly enhance the benefits of using the Coils.  Details will be posted as more information becomes available. InkBird units also sold separately, and are not included with the Coiled Lids.  

Wetsuit material will work very well, for you DIYers.  

If you have any questions, please feel free to send an email.  Happy to Help!
