Here we are offering a ceramic fiber gasket for a 30 gallon steel drum which prevents gasses from escaping from between 2 pieces of metal or from between metal and masonry/stone material. It can be used for to make a removeable lid for your Rocket Heater.
For example, suppose you acquired a nice piece of soapstone and wanted to make a top for your steel drum on your rocket heater. Create a circular groove in the soapstone with a router and then put the gasket in the groove to seal the interface between the metal and the soapstone.
This gasket is already included in the Dragon Heaters builds which need it.
If you order this item by itself, we mail it to you folded in quarters.
