Don't go without a seal on your Fermenator or HopRocket! This is a replacement T-handle for the lid seal v-band clamp on your Blichmann Fermenator or HopRocket. With it, you clamp down the v-band clamp, ensuring a proper seal so that it can be secure, without any leaking issues. With the old stainless steel model, the threading could seize if not properly lubricated (in accordance with Blichmann's instructions) and ruin the v-band clamp. This zinc version will not damage the stainless steel v-band clamp if such a case occurs. While the T-handle may be damaged, it is cheaper than the v-band clamp, or the old stainless steel T-handle for that matter. If you are in need of a new T-handle, we've got you covered!
