Oring inside female quick disconnect.... (bad week for orings around my house)

[JCD]

The funny part is the first two orings were on the pressure washer hoses and I had a very wet and cold Saturday. I need to finish tomorrow but they should be good now.

Now, as mentioned in the title, the sealing oring inside the female quick disconnect blows out on me. I've replaced them before but it was a best fit thing and had to fight some fittings on to it after, I have time to do it right this time if anyone can share the actual info, of course if they differ across manufacturer I might be back to 'best I can do' scenario.

I don't know the manufacturer but I have emailed the retailer. I'll update if/when I here back if no one else is able to enlighten me.

The O-ring in a female Foster fitting is a -010. A common Buna-N in 70 durometer will work just fine.

You are right that the O-ring size differs across manufacturers. I have several female quick connectors from China. All have dual O-rings but some are designed to have the O-ring pressing against the end face of the male connector so the O-rings are a lot thicker. The others have the O-rings slipped onto the stem of the male connector so they are thinner. All the female connectors have an internal shoulder holding the O-rings in place but they can still be blown out if you disengage the connector under significantly high pressure but that' s not a normal operation.
