Additional

To connect to a reverse osmosis tank, first apply 5-6 wraps of Teflon tape to the 1/4" threaded connector on the top of the tank, then screw the valve onto the tank.

To connect tubing, first make sure that the tube is cut flat, and not at an angle. Push the tube into the fitting past the o-ring as far as it will go, approx. three-quarters of an inch.

To disconnect, push the collet into the fitting and hold it down as you pull out the tube.

To open, turn the lever parallel to the tube. To close, turn the lever perpendicular to the tube.
