When combined with other Tri Clamp fittings, clamps, and gaskets, sanitary spools can build a process line without the need for on-site welding and fabrication, and at a considerable time savings. Tri Clamp spools also have the added benefit of being less permanent than welded tubing, and can be easily disassembled, moved, or reassembled in a different configuration. The versatility and cost savings of prefabricated spool pipe make them a popular solution for piping needs.SpecificationsTri-Clamp Size4"Material304 Stainless SteelStandard3A High PolishSpool OD4"Spool ID3.834"Flange OD4.682"Bead Center4.344" OD = Outer DimensionID = Inner DimensionDisclaimer to Customer:User assumes all responsibility and risks of the system for all Stainless Steel Parts bought separately to piece together a Closed Loop, Closed Column, or Open Blast Extractors.
