Garden hose fittings and couplings are parts that connect garden hoses to a water source or another hose so water can flow through a system. Garden hose fittings are installed on the ends of hoses for attaching to spigots, nozzles, sprinklers, and other hoses. They are often used to link to hoses or accessories that have different thread types or sizes. Garden hose couplings are typically used to temporarily connect two hoses with the same diameter together. These fittings and couplings are used in garden hose assemblies to water gardens, lawns, trees, and other plants in landscaping, grounds maintenance, and agricultural applications.
