These are foolproof industrial nozzles designed to last a lifetime.
Created in the 1940s for filling radiators at gas stations, the design has remained virtually unchanged since. Their unique on/off trigger is activated simply by flexing the rubber hose with one hand to generate and regulate water flow. Releasing the hose shuts the water off again with no dripping. With no moving parts to break, the nozzles are almost indestructible and won't leak, even when driven over by a car.
The jet nozzle, a powerful all-purpose sprayer for washing around the home and yard, reaches second-story windows with ease (total horizontal reach is 33' using a 3/4" diameter hose at 60 psi).
The fan spray model works best for watering large gardens, as it will easily reach a distance of 22' (using a 3/4" diameter hose at 60 psi), which is an advantage over most nozzles that either can't reach that far or need to be angled upwards to achieve any distance.
Made of rubber with brass fittings for standard hose connections, they are 8-7/8" long and available individually or as a pair.
Made in USA.
