This is a copper whiskey helmet with your choice of 3" or 4" triclamp connections. Whiskey helmets mitigate puking and allow the expansion of gases for a small increase in passive reflux and vapour-to-surface-area contact. The addition of a whiskey helmet below a column also allows a small pressure drop in rising vapors.
The whiskey helmet includes a 1/2" NPT threaded port with respective thermometer.
These are of one-piece construction with tig welded ferrules.
Free shipping included.
