Is my new brand-new accumulator toast?

So there I was, finally connecting up all the parts of my new AC system. Or rather, I got the liquid line connected with no problems, but I just couldn't get the accumulator-to-evap hose to connect. I don't have the strength to put enough force onto it from the awkward angle you have to use.

After wrestling with it for about an hour I've admitted defeat, and I'm going to let a shop do it (the same one that would otherwise just be doing the vacuuming and charging). But I won't be able to get the Jeep round there until tomorrow, and the accumulator is now filled with half the full system charge of PAG46 (as per the installation instructions that came with the compressor) and it's been exposed to the air, although the hoses are now capped again.

Will the accumulator still be OK, or do I need to junk it?

You should be ok, the vacuum pump-down will remove any air/moisture that got in. Just keep it capped until you turn it in to service guys.

I've had trouble with that very same connection. I think sometimes the spring binds or jams inside the springlock fitting and won't slip over the flared end of the tube it's joining. Twisting/rocking while pushing usually helps but it's hard to do that with this particular junction. I think in the past I've loosened the accumulator bracket which allowed me to move the whole assembly so I could get these snapped together.

I actually pulled the entire bracket out, but even with much more freedom to move the accumulator canister around, I still had no luck. It's just millimeters away from clicking home, I know it is, but I can't get enough force onto it. I hoped that a crowsfoot socket on the end of some long extensions would fit around the hose and give me something to push against, but the biggest socket I have - 19mm - isn't quite big enough.

Just one of those unbelievable frustrations. If it had clicked in, the rest of the system would have been connected up in about 10 minutes.

@SAR-Swimmer - thanks for the reassurance Accumulators aren't as cheap or readily available here as they are in the USA, so replacement is a bigger deal.
