The Integra X-Stream Mixing Tip features a bayonet fitting, so you don’t need to worry about saving a retaining nut for holding your tip in place. The bayonet fitting makes for fast, easy attaching and removal. The X-Stream separates the two components from the nozzle of the cartridge, eliminating cross-contamination. Its unique design divides the activator into two separate streams the adhesive into 4 streams to ensure excellent mixing throughout. This allowed the tip to be made smaller, and vastly reduce the amount of wasted material left stuck in the tip housing.
