A fire hose coupling comprises a first coupler body having a first recessed portion that includes a first visual indication. The coupling also comprises a second coupler body adapted to be coupled to the first coupler body to form the coupling, the second coupler body having a second recessed portion that includes a second visual indication matching the first visual indication. Color-coded stickers or adhesive-backed high-visibility decals may be adhered to the recessed portions. The couplings may be recoded by adhering differently colored stickers. This technology enables firefighters to quickly and easily color-code their hoses for identification purposes. Because of the recesses, the color--coded stickers are substantially protected from abrasion or wear and tear.
