A pipe coupling includes first and second coupling shells, each of which shells define a semicircular cross-section, and first and second longitudinal flanges, and wherein the shells are hingedly coupled together about the respective first longitudinal flanges. Fasteners secure together the second longitudinal flanges to enclose two longitudinally-spaced sections of pipe with a generally cylindrical housing. The first coupling shell further defines a port extending radially therefrom into which a grommet is preferably disposed. The grommet defines a normally-closed aperture for passing a needle therethrough for injecting a chemical, such as a disinfectant, into fluid, such as water, in the pipe.
