Depending on how you mount your glue applicator head will determine the type of nozzle needed.
There are options for 90 degree applications:
The standard 90 degree nozzles - fit standard 1048115 or 276119 Nordson modules:
If you need to apply adhesive where space is limited, you may want to consider using an extended nozzle that is drilled to shoot at 90 degrees. This nozzle will also fit the standard Nordson modules. This nozzle requires a retaining nut - KNRN238. This nozzle can rotate to adjust where you need glue to be applied.
Another option is to use a needle nozzle in a right angle module. The limitation with this setup is that the nozzle is fixed and cannot swivel versus the swivel on the right angle nozzle as shown in the first picture above.
