There are a number of static mixer tips available to meet different application needs. Here are a few of the most common tips.  Stepped Tip: this tip is layered and can be cut at different intervals to control the bead size being dispensed. This is probably the most common type of nozzle tip. Tapered Tip: this tip tapers to a small cone and, unlike the stepped tip, is not meant to be cut to change the bead size. Luer Lock Tip: this tip is used to attach needles or other attachments for precision or specialty dispensing.
