14-gpm injector lets you add precise amounts of product directly into water lines

14-gpm, non-electric injector is mounted in water lines and injects preset amounts of product directly into the water supply for the perfect amount each time. Ideal for fertilizer, insecticides, fungicides, algaecides, wetting agents, acids, disinfectants and more. Consistently accurate and unaffected by variations in water flow and pressure, this injector is easy to maintain and operate, has an easy-to-adjust ratio and can be used in water with a maximum temperature of up to 104°F

This injector can be mounted on booms or benches, or used in conjunction with our portable 15-gal. Dosacart (Item # 192234) or 5-gal. Li'l Bud-D Dosacart (Item # 192235) for reliable, accurate fertigation on the go. 3/4" NPT fitting. Includes 6'L tubing, weighted strainer and mounting bracket. Imported.

NOTE: A 200 mesh filter (Item # 192230) should be installed on the inlet side of the injector and is required for a valid warranty.
