SS Cooling Coil Lid (4" Threaded) 

For 6.5G, 7G & 8G Conicals

Food-grade stainless steel • Built-in temperature control coil  ❄️🌡️

Simple, Reliable Temperature Control — Built Into Your Lid

Upgrade your MiniBrew conical with a stainless steel cooling coil lid designed to help you cool and hold fermentation temperatures with clean, closed-loop recirculation. Pair it with a pump + cold source (glycol chiller or ice bath), and you’ve got dependable temp control without adding anything inside the fermenter besides the coil itself.

This is a standard 4" threaded lid and includes a fresh Buna-N gasket for a snug, leak-resistant seal.

How It Works (Quick) 🔧

1. Attach tubing to the coil connections

2. Run the lines to a pump
