This Polypropylene Faucet Adaptor connects between the bottom of your faucet and the top of the riser tube that runs between your cold water shut-off and the faucet.
To install, simply disconnect the riser tube from the faucet and thread on the faucet adaptor. Then thread the riser tube on to the bottom of the faucet adaptor.
With a 1/4" quick connect fitting built-in, this fittings makes a great supply connection for Reverse Osmosis Systems, Under Sink Water Systems or Refridgerator/Icemakers.
We recommend using a John Guest Ball Valve with the Faucet Adaptor.
