ABSTRACT:
Dispensing apparatus and methods related to a nozzle, gun and filter for dispensing viscous liquid materials. The nozzle includes a nozzle body having a dispensing orifice with a diameter and an engagement dimension. A first visually identifiable indicium is provided on the body portion to indicate the orifice diameter and a second visually identifiable indicium is provided on the body portion independently from the first indicium to indicate the engagement dimension of the nozzle. To provide for easy and precise indication of the nozzle, at least one of the first and second indicia is a colored marking. A dispensing gun and filter used, for example, in a hot melt adhesive dispensing system also incorporate generally similar indications of nozzle orifice and engagement dimensions.
