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 any of our H503 and H507 Series of quick disconnects. However, it does not work in conjunction with any of our plastic or Brass quick disconnects. These feature a 1/2 inch male National pipe thread on the 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 inch ID. Gasket temperature range is -40° to 250° F. Open port, does not have shut-off. We designed the original stainless qd's for the brewing industry over 10 years ago. The same manufacturer has been machining them for us ever since. The design has certainly been copied but not with consistent quality. That is why our stainless QD fittings have a near unanimous 5 star review with retail customers. Please note: this product will not work with our Brass or plastic quick disconnects.
