I ran into a problem when I re-did my exhaust. I installed a new cat with the air injection port and when I removed the old one, which was held on with a U-bolt, I removed said U-bolt and had to cut the tubing because of the crimp the U-bolt created. My dilemma now is how do I connect the tubing from the air pump to the cat? The part I had to cut was flared to fit over the port on the converter. Is there a tubing union that will work? looks to be close to 3/8" tubing but I could be wrong. Any suggestions?

I did the same job about a month ago- I ended up using some "hi temp" rubber hose from the local parts supply- it's only a temporary fix but all seems fine so far. The appropriate fix would be to either reflare one end and braze/weld or add a coupling. There's always air pumping through this cooling it so the heat from the cat won't burn it. At any rate it will last until you can find an exhaust shop. This fix has 100~ miles or so and shows no sign of heat damage- also it doesn't hang below the cat, it's just the angle of the shot.
For what it's worth, I have the same temporary fix in place (hi temp hose with hose clamps). I've put just over 200 miles on the car with no issues. I wouldn't leave this in place permanently though.
If you don't have enough length in your existing AIR tubing to reach the new cat, I'd imagine you could get a section of steel tubing to make up the difference (rather than replacing the entire length of tubing). You could flare both ends of the steel tubing so it fits over the existing AIR tubing and the port on the cat or just use tubing with a slightly larger inner diameter than the outer diameter of the AIR tube and cat port. It wouldn't be the cleanest thing in the world.

What size tube is that? I may run into the same problem.
Compression fitting. Muffler shops sold a repair kit with the hose, but I knew there had to be something better fitting and better looking. Don't remember the size of the fitting, but it's not an odd size, and it fit perfectly.
