This is the Female QD.  When used with the male QD these quick disconnect seal up very well in either flow direction, without a lot of work in connecting them. This will work with the H503 and H507 series of quick disconnects. However, it does not work in conjunction with  plastic or brass quick disconnects. These feature a 1/2" Male National Pipe Thread on the outer ends for easy connectivity to almost anything.

The quick disconnect will hold pressure for typical brewing applications when moving liquids at 60psi or less. 1/2" ID.   Open port, does not have shut-off.

Please Note: This product will NOT work with our Brass or Plastic Quick Disconnects.
