Carbide angle nozzles are available with one, two or three exit ports. Generally the 2 and three port angle nozzles are used for blast cleaning inside tubes or boxes where the abrasive can be aimed at more than one inside wall or inner tube/pipe surface. Some jobs may need a combination of nozzles to reach inside tight angles or partially enclosed areas. Another useful tool for cleaning hard to reach areas are curved nozzles. Our Curvo Blast ™ nozzles are unique in that they incorporate a curved liner formed out of a single continuous piece of carbide.
