Through the Wall Fitting, Tri Clamp 1.5" x 2.5" x 15", SS304
Through the wall fittings are an elegant solution to attaching Tri Clamp
components inside a tank, commonly a mash tun sparging arm, CIP spray ball or
liquor tank herms coil. Through the wall fittings attach to an exterior tank
ferrule (Tri Clamp 2.5") and protrude their Tri Clamp connection into a tank.
**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, a [1.5" Tri Clamp to 1/2" hose barb
adapter](https://triclamp.co/products/tri-clamp-to-hose-barb-
adapter?variant=30851417554) is 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 to [contact
