Toe nipples are short, threaded metal pipe connectors designed to join two female-threaded fittings when space is limited and precise spacing matters. Positioned between close nipples and longer pipe nipples, they provide just enough length to simplify installation, adjustment, and future maintenance. Commonly manufactured from galvanized steel, black steel, brass, or stainless steel, toe nipples are built to handle the demands of plumbing, irrigation, gas, and mechanical systems.
