Eyewash easily mounts to faucet and still allows normal sink use. Simply push the pin to activate the eyewash—an eliminator valve keeps the eyewash constantly pressurized. Hands remain free to hold eyes open as eyes are rinsed simultaneously. Push the pin the other way to allow water to flow through the faucet. Eliminator valve also allows for the water temperature to be pre-set at the faucet and remain on to provide tempered water. Delivers over 0.4 gallons of water per minute. Includes two adapters.
