This Quick-Connect Union Shut-Off is the perfect fitting to use when you are installing any water ionizer or filter system which uses 1/4 inch hosing. It allows you to easily shut off and on the water flow to your water ionizer while it also allows you to adjust the flow-rate to the exact speed you want.
It's great for traveling and for everyday use. It's much easier to use this quick-connect fitting, rather than un-screwing the diverter on your faucet.
