I've got a brand new Sanden compressor and I'm finding myself unable to hold a vacuum now. I replaced all the o-rings to be safe, but I think the problem is in my r134a conversion fittings. I attached some pictures of the pieces I'm using:
I've tried the cheapo aluminum ones available at all auto parts stores, and I've been disappointed with them leaking. I'd also really like 90-degree angle ones like this, since they seem to fit better, but it's not a hard requirement. These seemed good, but I think I might have over-tightened them since the o-ring now looks destroyed on my high side adaptor. And I can't remember where I bought them, so I can't just go order another set.
Who has a good source for these? I don't think our host does, so should be safe to share the secret. Here's the only one I've found online, but I'd prefer to buy from somewhere people have had good luck with buying such things.

Any suggestions?
