3" x 18" Sanitary, 304 Stainless Steel, Tri Clamp Spool, BHO Extractor Column

3" x 18" Spool with 3" Tri Clamp Connection

Spools, also known as sanitary spools, are pre-fabricated lengths of stainless tubing with Tri Clamp fittings welded to both ends for customer convenience. These can be used in conjunction with other Tri Clamp fittings, Tri Clamp Clamps and Silicone Gaskets (all sold separately), allowing the user to easily manufacture sanitary pipelines without the need for costly on-site welding and fabrication. 

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 1.5" Tri Clamp to 1/2" hose barb adapter 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 us .
