<P><FONT size=2>Yeah, I don't think there's really any issue of the R12 and R134 being used with the same o-rings. Of all the o-rings I played with and replaced with my wife's NX a few years ago, I didn't notice any of them with wear and tear that would indicate disintegrating</FONT></P>

<DIV><BR>>> I would tend to say that if you're removing all of the original<BR>>> refrigerant anyway, might as well change the rings while you have the<BR>>> chance.<BR><BR>> What are there like 15 of them? <BR></DIV>
<P><FONT face="times new roman">Something like that. There were a LOT. I know I got an o-ring kit from an auto parts place and I think I even needed two of them because they didn't have enough of the one size. And in the end I was cursing myself for wanting to replace the o-rings. Like I said, some of the connections were real fussy. I don't know if that's normal or just because it was me but they wanted to be tightened EXACTLY right. Too tight and the o-ring slipped out of place and you got a leak. Too loose and the o-ring didn't seat and you had a leak. I can't tell you how many cans of refrigerant I went through trying to get all of the damned o-rings to seat properly (and probably contributed significantly to global warming - take that Al Gore!) The only way to tell was once the system was back together to try to fill it and look/listen for leaks. I'd definitely stick with the better left alone theory on this one.</FONT></P>

<DIV><FONT face="times new roman">I don't ever remember evacuating the system. Just filled it up. I think I might've purged some 'air bubbles' too when I overfilled it and needed to back off the pressure via the high pressure line </FONT></DIV>
