The circular nozzle is made for compressed air activation, and it has a standard 45o bend hose connector made of metal or moulded rubber.
The most common sizes are ø100, ø125 and ø160 but other diameters e.g. ø200 and ø250 are available upon request.
Some of these nozzles have a Kevlar or Carbon lining which reduces friction and resists higher gas temperature.
Your company name and logo can be stamped into the nozzle without extra costs.
