3″ x 40″ Copper pipe with a 3″ stainless steel tri clamp ferrule welded to the end. Also includes tri clamp and gasket. This is not a complete column. You can use this with some more copper pipe and some solder to build your own column.The 3″ tri clamp ferrule willconnect to any 3″ tri clamp ferrule on any of our moonshine still boilers that are sold with 3″ tri clamp connections. This copper pipe is type L, which is much heavier than type DWV or type M, which is sold by other vendors.All of our stills, still boilers and columns come with a 1 year warranty which covers manufacturing defects and leaks. This warranty does not cover our Beer Keg Stills.

DETERMINING TRI CLAMP SIZE

Tri Clamp sizes are determined by the outer diameter of the pipe or tubing, not the outer diameter of the flange or Tri Clamp itself. The flange of a Tri Clamp fitting typically has about a inch greater diameter than the outside diameter of the pipe. This can become especially confusing when the Tri Clamp fitting has no pipe attached to it, as is the case with adapters, For instance, a1.5″ Tri Clamp to 1/2″ hose barb adapteris not 1.5″ inches in any dimension, but the Tri Clamp end will fit any other 1.5″ Tri Clamp fitting.

If you have any doubts about what size Tri Clamp fittings your project needs, simply measure the outside diameter of the flange (dimension “B” below) and consult the chart below, or feel free tocontact us.
