Abstract

An extrusion nozzle assembly for use on a dispenser of molten hot melt adhesive. The nozzle comprises a heat conductive insert housed within a heat insulative plastic holder. A resilient seal within the holder prevents leakage between the nozzle and the dispenser when the nozzle is threaded only "finger tight" onto the dispenser.
