These tri clamp reducers are made from 304 stainless steel and are used to reduce or increase the diameter of a sanitary pipeline. A Concentric reducer is often used inline on a vertical flow application. This reducer meets all standards of the sanitary industry. NPT/NPS port size is based on NPT/NPS pipe size interior diameter (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 ½” 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  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  .
