Use a high-quality sillcock from Grainger to help control water flow in outdoor faucets, sprinkler systems and washing machines. Angle sillcocks feature solid brass construction with nitrile O-ring and quarter-turn handles. Freezeless faucet sillcocks can be left on during freezing weather and help to keep water lines from freezing up by stopping the water flow inside the building by means of a long faucet stem.
