A nozzle includes a housing defining a fluid passage (26). A member (14) is disposed in a position to block the fluid passage when the nozzle is not spraying fluid. A retainer (16) attached to the housing retains the member in the disposed position. The surface of the housing has one or more marks (48). The number of marks indicates the spray profile produced by the nozzle. The member is disposed within the fluid passage and bursts under the flow of fluid.
