Quick Connect Soap Nozzle

These nozzles are used for soap and chemicals in downstream injector systems (that is, systems that apply chemicals after the water has left the pump).  These nozzles aren't high-pressure nozzles, they're designed simply to mix chemicals with water and spray onto a substrate.  It's important to use a chemical tip when using a chemical injector; many times when people complain of their injector not siphoning, it can be traced back to the use of a high-pressure nozzle.  They work by using siphoning action (the same way you pull fluid through a straw) to pull more chemicals into the stream of water.
