Our Barbed Y-Connectors have been engineered to effectively join three pieces of soft-walled tubing together in a Y configuration, offering less turbulence and more gentle mixing of fluids than a traditional Tee Connector. This type of connector works well for joining three peristaltic tubes with similar inner diameters together. They are manufactured from polypropylene and are packaged either individually or as 10-packs (as indicated).
