Connect your garden hose line to a 1/2 in NPT-threaded plumbing port without improvised adapters. This 3/4 in GHT female to 1/2 in NPT male brass adapter converts a standard garden hose female coupler into a tapered pipe thread male fitting, letting you attach hoses directly to valves, manifolds, irrigation risers, and other NPT-port equipment. The heavy-duty brass construction resists the corrosion and pressure deformation that shortens the life of cheaper zinc or aluminum alternatives. A rubber donut washer inside the GHT end creates a face seal that stops drips without requiring PTFE tape on the hose side. Note that the 1/2 in NPT thread is a tapered pipe thread distinct from garden hose threads; verify your equipment port accepts NPT male threading.
