Tri-Clamp Sanitary Stainless Steel Tubing/Spool Assemblies
Make your fluid-handling systems more efficient than ever with our Tri-Clamp Sanitary Spool Assemblies. Custom-built from high-quality stainless steel to ensure purity, durability, and easy maintenance, these sanitary spools integrate seamlessly into your operation—from brewing to pharmaceutical production. Tri-Clamp spool tubing also has the added benefit of being non-permanent, unlike their weldable tubing cousins, and can be easily disassembled, moved, and reassembled in a different configuration. The versatility and cost savings of a prefabricated sanitary tubing makes them a popular solution for tubing needs.
Whether you’re expanding operations, managing existing processes, or performing routine maintenance, we carry a full range of additional parts to complement your Tri-Clamp Sanitary Spool Assembly. From gaskets and clamps to valves and fittings, our inventory ensures you can quickly find everything you need to keep your systems running smoothly.
Additional tube sizes, lengths, and finishes are available for custom order. Please contact our sales team to get started.

Do you make or sell any TC fittings that have a dip tube attached? Specifically I am interested in a 1.5” Tri-Clamp. We are using this fitting to connect to a bulkhead for a liquid input and would like to direct the liquid stream straight down into the vessel with the dip tube, to ensure the liquid does not drip down the side of the vessel. We will be connecting the dip tube to a 1.5” Tri-Clamp on the bulkhead and a 1.5” Tri-Clamp to barb adapter (both from Sanitary Fittings).

Q what is the pressure rating of a spoolA
All of our tri-clamp fittings have pressure ratings that are dictated by the type of clamp used in the process line. The pressure rating is also affected by the temperature of the media that you are processing. For exact pressure ratings, please consult any of our Tri-Clamp Clamps for the size that you are working with and it's corresponding pressure rating.
