The KBR NOZZLE is a descaling nozzle designed to work in pipes up to 6”. It is a great nozzle to use when working in heavy grease or root blockages. It is equiped with 4 rotary jets and 3 rear jets, or 4 rotary jets alone. If the 3 rear 4 rotary jet nozzle is selected, the rear jets can be plugged if more focus is needed on the rotary jets. If this is the case, the nozzle will have less thrust, but will be able to focus more on rotary performance and pipe wall cleaning.
