Guts hanging out if my new SS quick connect?

[jcims]

Hi all. First post with the phone app, apologies in advance for screw ups.

In a fit of impatience I ran some 3/8" hose from my rear remote to my loader to get some grapple time in before the winter. Everything has worked beautifully, except for today when I tried disconnecting it for the first time.

The male coupler on the grapple side was hung up a bit, so I did what I always do and just pulled harder. :/ Well, it came out, and pulled what appears to be an unhappy o-ring with it ( see attached? ).

I'm assuming this bit of rubber belongs inside the female portion, correct? And given I just bought this a couple of weeks ago, and this was the first time it had been disconnected after being pressurized (by me anyway), that this was likely faulty to begin with?

So I'll do my dance with TSC to get it replaced, but my questions are:

A) aside from not pulling on it like an ogre, was there anything I could have done to prevent/cause this?
B) since the 13' of hose hasn't seen any flow since this happened, is it reasonable to think that blowing it out with some air/fluid would likely remove offending bits of rubber from the system before they screw anything else up?

Thanks folks!

I had this happen on one of my connectors and it is not really an o-ring.

It looks like one, and has the same purpose, but does not have a circular cross-section.

Mine was an off-white color instead of black, but looked a lot the same.

I ended up replacing the whole fitting, with a genuine Parker instead of the Italian brand that I originally had.

Did you disconnect under pressure?

Some QD couplers, and flat face couplers are designed for disconnect under pressure and some not recommended.

They talk about seal extrusion and it probably has to do with the pressure.

What brand of coupler do you have?

There are o-ring kits for repair on some of the QD's

Thanks guys. This actually is a Parker, purchased from TSC a couple of weeks ago for $50-ish. I don't believe there was much pressure when i disconnected it. The 'other side' in this case was a set of very beefy couplings that Gator Attachments puts on their lightweight grapple. Both sides look good visually, no burrs or anything that I can see that would grab the seal, I'm guessing it just got pushed out of place and pinched in the barrel of the coupling, and then just got 'rolled' out when i pulled them apart.
