Automotive AC parts

[Legacy777]

I bought a AC manifold gauge set a little while back. It works fine, but the connections to the service ports leak a little, and need to be replaced, however I haven't been able to find a place online or locally to buy just the connections to mate up with the hoses.

All the local AC shops are more home AC stuff, and not automotive. My local auto parts stores really don't have squat.

Anyone know of any place online where I can get automotive AC stuff?

TIA
