Hose bibs, water hydrants, and sillcocks allow you to control water flow. Grainger has an assortment of these water controls in a variety of body materials, handle materials, and handle types ideal for many plumbing applications. Body materials are corrosion resistant and some models are frost proof for use in subzero temperatures. Wall hydrants contain a secure valve for shutting off the water and include a key for turning the water on and off. Some hydrants have a locking door as an additional aid against tampering and include an anti-siphon vacuum breaker that prevents back-siphoning of water into the water system. Wall and yard hydrant accessories include hydrant keys and hydrant seat wrenches for specific hydrant models.
