Abstract
A fire protection sprinkler includes a body having an inlet end, including a threaded base configured to connect to a fluid supply conduit, an outlet end, and a water passage defined therein. The water passage includes an inlet orifice, provided at the inlet end of the body, an output orifice, provided at the outlet end of the body, and an interior surface formed of a material having a weighted average lead content of 0.25% or less. A seal cap, that moves between a closed position, in which the seal cap seals the output orifice of the water passage, and thereby prevents flow of a fluid from the fluid supply conduit through the output orifice, and an open position, in which the seal cap does not seal the output orifice of the water passage, has water-exposed surfaces formed of a material having a weighted average lead content of 0.25% or less.
