heater core hose(return) leaking
Audi a6 c5 v6 AGA
As my post couple weeks ago, my heater core hose (return) is leaking at the quick coupling connected to engine. The o-ring in quick coupling is worn.<img src="http://pictureposter.audiworld.com/2/heater core hose o-ring.jpg">
however, I check the coupling housing is fine.So I am wonding if I can buy a o-ring only, not a whole hose (very expensive),but there is no any information about the o-ring in ETKA.
Could anyone help to give me the P/N of the o-ring.

You can likely bring it into NAPA and they will match it up or you could just purchase an o-ring kit at harbor freight for around $10. I picked up the kit last year and replaced all the coolant o-rings when I had the engine out.
