Solo sprayers are built for comfort, convenience, and durability. The professional-grade, triple test inspected sprayers are proudly made in the USA. The Solo 425 features a connecting rod-actuated piston pump, capable of producing a wide pressure range of up to 90 psi. This allows it to handle virtually every spraying task, from applying spray liquid to insecticides in the garden. With a proven piston pump, the Solo 425 ensures reliability and long service life with minimal maintenance required.

The ergonomic design contours to the user's back, providing greater comfort during extended periods of use. The 4-gallon 90 psi high-pressure backpack sprayer features an ultraviolet resistant tank, felt padded polyester straps, a heavy-duty pressure cylinder, and reversible pump lever. Made of high-grade, corrosion resistant plastic, it has no vulnerable metal or rubber parts. It can handle disinfectants, fertilizers, herbicides, and pest control products efficiently for tree, shrub, and plant protection.

Solo's 425 backpack sprayer has been the standard for backpack sprayers in the US market since 1964. The high-density polyethylene tank, with ultraviolet inhibitors, provides unmatched durability and protection. It also features a large opening for easy filling and cleaning, an overall length of 28 inches for hard-to-reach places, and a 4-foot high-pressure hose. The 425 backpack sprayer is designed to handle a wide variety of tasks, from tree and plant protection to wood and concrete finishing and treatments.

The sprayer comes with a one-year warranty, and with proper maintenance, it is built to last for many years of use. It is equipped with adjustable, flat spray, hollow cone, and jet stream nozzles to accommodate different spraying needs. The padded straps and pull tabs make adjustments quick and easy, and the built-in strainers, screens, and filters help keep debris out of the nozzles.

The Solo 425 backpack sprayer also includes an unbreakable wand that connects to a 48-inch nylon-reinforced high-pressure hose for extended reach. It comes with four easily changeable commercial-grade spraying nozzles and a commercial shut-off valve that minimizes user fatigue.
