3/4" Supply connectors and ball valves

This fitting is typically used to connect an Under-the-counter Filter system to a 3/4" (20mm) water source. For example in most households, the supply connecter will be connected in between the angle valve and flexible hose that feeds cold water to a washing machine or dishwasher.  The water will then still flow to the normal tap, while the 1/4" or 3/8" ball valve that "T-ing" out from the connector, will supply water to the filter system. The 3/4"  Supply Connector includes a "blank"  fittings, which is used when you want to connect to a wall-mounted mixer tap, with the cold side having the 3/4" connector with the 1/4"  hole, and the hot side having the " blank"  this means the mixer tap can be move forward from the wall evenly.
