You could use something like Swagelok or Parker compression fitting with flexible copper or stainless tubing. I use this on my compressor with stainless flexible tubing, the tank pressure goes to 200 PSI.

or flexible stainless hos which you can get in different lengths:

Thanks for the link. Going to try and sourced some annealed copper tubing locally. On Lowes and menards website looks like the annealed stuff only comes in coils.

I am not seeing those in a 1 inch NPT and 1 inch tube or maybe my google foo isnt working.
 
You have to visit their online store to find the 1" (they do have it in a couple of lengths). I believe though, that the actual application intent for those hoses is to run from tank outlet/valving to the building. This isolates the rigid piping in the building from vibration and allows considerable misalignment between the building and the compressor. If memory serves, these have a Teflon liner, and may be good for some higher temperatures, but I would inquire about that before running straight from the head to the tank. That air is still plenty hot.
 
You need to run copper from the head to tank . It will help get rid of the heat. The cooler your air gets the water will drop out in the tank and you can drain it.
 
Copper is better at dissipating heat. The SS flex tubing listed is all metal and uses corrugated SS tubing with an outer mesh and rated to 500PSI, higher than copper. You can always email the vendor if you have questions on the suitability and size. There is much more surface area with the corrugated SS pipe, but it has poor thermal conduction properties. In either case, I do not think it will make much difference temperature wise as the copper is not finned and the run is short. In my experience in the lab and also boat building where we used this corrugated SS, it can handle much higher pressures than copper and some pretty harsh conditions. When I had bigger compressors I would use coil copper tubing between the tank and my filters to cool the air and condensate the moisture.
 
Soft copper will normally come as a roll. And here, stores/supply houses won't cut it for you. Maybe you could corner a plumber and strike a deal with him, since you need such a short piece. In fact, I may have a piece. I'm not a plumber, but I have done a bit of it and may have some drops. I'll check in the morning. I'm pretty sure I have some hard 1", but not so sure on the soft. I've tried a couple of times to anneal and bend some of the hard alloys, but no real success. The trick I believe to bending it would be to anneal it, then fill it with lead, make the bend(s) then melt the lead out. Of course, copper work hardens and if the bends were extreme, you would have to anneal it multiple times during the process. Oh, and I believe the wall thickness is less on the hard types of copper as compared to the same size in soft. Virtually any of the common alloys tubing comes in is more than sufficiently strong.

On "How It's Made" I recall seeing them fill brass tubes with water, or something in solution, then freezing them, bending the pieces over a form or mandrel. They were showing the manufacture of musical instruments such as trombones and tubas if I remember correctly.
 
I think what I am going to do is buy a couple short sections of the Flexible SS pipe to go out of the head and into the tank than buy 5 feet of the soft copper and bend a bunch of s curve into it than figure out a way to mount it and attach the stainless pipe. And hopefully do all this for under 150 bucks.

Heck now that I think about it I cold even take the copper directly to the tank and just have the SS out of the head to dampen the vibration.
 
I would suggest just using the heavy wall soft copper tubing with double ferrule compression fittings directly from the head to the tank if it is all is rigidly mounted. If not than some flex would be reasonable. On my Curtis compressor, they just used some bent pipe out of the head directly to the tank, I believe it was heavy wall copper. It would get very hot.
