"Fittings with multiple o-rings have more areas of potential failure. We have taken steps to improve their reliability. The largest change has been in switching to EPDM rubber (black) o-rings from the earlier silicone (red). It makes swiveling joints a little harder to rotate and QDCs a bit harder to connect/disconnect, but the material is more robust. We have also reduced fit tolerance on many fittings.

Our EPDM o-rings are available separately on our website, but not all types of fittings can be serviced in that way. Later angled nozzles and female QDC fittings are permanently sealed. Generally, the internal o-ring material will match the thread collar o-ring (which is visible)."
