Renowned as the professional's workhorse, the popular High Performance Series has just been pumped up with inspired new features. Each nozzle is precisely made on the industry's most sophisticated machinery. They are hand tested to assure accurate control and fine atomization of the spray, and they are self-sealing, which eliminates the need for messy sealers. Unlike conventional brass nozzles, steel alloys are more durable and resist damage from harsh chemicals.
