Chapin has manufactured superior compressed air sprayers for the professional since 1884. Our most revered sprayer in the concrete industry, the Xtreme 19049, has been called the "famous red can." It is well known among Concrete and Hardscape Professionals for its reliability, performance and long standing reputation to perform. You will see these sprayers in the backs of trucks, on job sites, just about anywhere cement work or hardscape cleaning and sealing is being done. No matter what you must spray, there is a Chapin Sprayer that will meet your need and exceed your expectations. Xtreme seals and gaskets, brass shut-off, 36 Inch brass extension and large mouth opening make this the toughest Chapin Industrial poly sprayer in the poly line-up. Each have a Lock-on feature. A red lock-on feature indicates shut-offs containing Xtreme Seals to handle more corrosive chemicals. Poly open head tanks have a built-in pressure relief valve that prohibits the tank from being over pressurized and allows the user to exhust pressure before losening or removing the pump cap.
