Anyone know where to find this type of compression fitting for copper tube? I want to replace these nasty rusted ones before I reinstall this check valve. I'm also looking for a 3/4" 90 deg elbow compression fitting like the smaller one in the picture.

That is a flare fitting not a compression fitting. Also those are brass not steel so they are tarnished not rusted. Those fittings are available in any good hardware store.

That fitting was put on and then the copper tube was flared. I understand you want it to look newer, but you'll probably end up buying new copper tube and use a flaring tool if you go this route. Or paying someone to do it. Another alternative is to replace the copper line and the compression fittings with a hi-temp stainless steel braided line. For individual fittings, your local plumbing supply house will have them. Another option is to take your old parts and go to your local air compressor dealer. They should be able to make exactly what you need on the spot, including bending new tube. But they may look at you funny and question why you want to do in the first place. Or look up the parts manual for your compressor and buy the assembled part online.

It will be worth the drive to visit a good local hardware store or plumber's supply. Be sure to carry all your old plumbing with you for comparison.

Looks like these are actually inverted flare fittings. And unfortunately those fittings on the copper tube are steel. I'm fitting a different pump that was originally plumed for 5/8" fittings to a tank originally plumes for 3/4" fittings. I'm going with 3/4"

Hard ot tell in the pic but the male thread is 1/2'' or 3/4''. Maybe consider using hydraulic hose and pipe thread fittings. Depending how it is piped it maybe easier and better.

The trouble is, no one knows where 'here' is...we could maybe help better if we had an idea what state or country you were in.
