Versatility is key when maintaining your yard. The RYOBI 1 Gal. Chemical Sprayer Tank is compatible with both the RYOBI ONE+ 18V 1 Gal. and 2 Gal. Chemical Sprayers. Mix your fungicide, herbicides, or pesticides into their own designated tank so you can store your chemicals separately when not in use. The 1 Gal. tank is lightweight, and sprays up to 30 Gal. per charge. Equipped with a cap that doubles as a mixing cup this spare tank accessory is built for convenience from prep to clean up. Attach this tank onto your RYOBI ONE+ 18V 1 Gal. or 2 Gal. powerhead and with the push of a button you are ready to go, no more pumping required. Backed by a 3-years warranty, RYOBI has the solution to all your outdoor needs.
