2" x 1.5" x 1/4" MNPT Tri Clamp Reducer, SS304
Tri Clamp concentric reducers decrease in diameter towards the center this
forming a conical cylinder. A concentric reducer is often used inline on a
vertical flow application, or if laid horizontally, as an increaser. We do not
recommend reducing in the horizontal as pooling may occur. In these cases, an
eccentric reducer, which lays flat on one side is preferable. Concentric
reducers have a lower chance of producing agitation like an end cap reducer
may, NPT/NPS pipe size interior diamter (ID).
**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
