This Danco standard adapter will connect a female garden hose to male faucet. The adapter will also connect a female or male aerator to male faucet. This adapter offers an easy connection. This garden hose adapter is chrome plated for greater durability and will endure the rigors of everyday use. Aerators limit water flow through the faucet allowing water use to be reduced compared to the same time flow without an aerator. In the case of hot water, because less water is used, less heat energy is used.
