- Replaces: Nordson part 954012.
- Used in: Glenmar HG8000-STD hand glue gun, our aftermarket version of the Nordson AD-31 extrusion hand gun (274765).
- Specs: single, 0.275″ x 0.375″.
About the AD-31: Nordson’s AD-31 series manual covers the AD-31 models and the L4 hand gun. The grip holds no heated parts or adhesive channels, so it stays cool; the heater, temperature sensor and adhesive path sit in the gun body inside the shell.
