Compact, durable, and built for the toughest chemical applications, this 0.4 gal. acid resistant handheld sprayer is the go-to tool for professionals across concrete, cleaning, sanitation, vehicle care, and industrial maintenance. Designed to handle a pH range of 1-9, this sprayer stands up to highly aggressive agents without compromising performance. FPM seals deliver outstanding resistance to a wide range of chemicals, and a specially coated spring combined with a non-return valve ensures the internal components never come into direct contact with the liquid - extending the life of the unit significantly. The closed pump head adds an extra layer of protection against dirt and contamination. The built-in safety valve and easy-to-read level scale give you added control and peace of mind during use, while the adjustable plastic nozzle allows you to dial in the exact spray pattern you need. A protective cap keeps the unit clean and ready between jobs. Perfect product for disinfection and sanitation, concrete and masonry, vehicle cleaning and detailing, corrosion protection, impregnation and surface treatment, and professional cleaning and industrial use.
