The parts that make up an outdoor faucet include a valve seal, supply pipe, spout, stem washer and spindle. Other faucet parts include a packing nut, packing washer and handle. An outdoor faucet can also include a water hose and nozzle.
The faucet's supply pipe connects the water supply to the faucet and spout, while the valve seal closes the spout. The handle, spindle, packing nut and packing washer control the valve seal, making it possible to adjust the amount of water coming out of the spout. All the parts that make up an outdoor faucet are made to survive the elements.
