Unijet spray nozzles from Spraying Systems Co, are a unique style of nozzle designed with interchangeable spray tips that allow you to maintain your spray while changing performance when necessary. Not only does a Unijet nozzle reduce the time it takes to switch out nozzles, but they minimize your nozzle replacement costs as well, as Unijet bodies can remain connected long-term, while spray tips only need to be replaced when worn out.
