We offer both MistAway slimline nozzles and Hago nozzles. If your system has large nozzles with a diameter similar to a roll of nickels, they your nozzles are probably Hago nozzles. These nozzles were the original nozzles used in older installations. If your nozzles are about the circumference of a pencil then you most likely have slimline nozzles, which were designed with aesthetics in mind. Both type of nozzles can have their tips replaced, although the slimline nozzle is easier to maintain than the Hago.
The MistAway slimline nozzles come in regular and nickel plated nozzles. Nickel plated nozzles provide extra corrosion resistance. The regular slimline nozzles also come in a 2" extender size which can be used in areas that require the extra length, like fences with ivy growing on them or can be used in systems layouts that include eave installations.
