Reusable/Temporary high pressure fittings.

I had the threads snap off a 3/4-in male high pressure hose at a changeover block today. I overnighted the part but if I had a 3/4 coupling of some sort to splice the high pressure hose I could have got the machine back going. What would you call it and does anyone make such?
 
There are "reusable" fittings for repairing hoses, but as hard as it is to assemble the 3/8" ones I can't imagine repairing a 3/4" hose with hand tools.
 
APW don't be spooked about this. I have been doing this for many years with no failures. And I am not a big brawny guy. There are a couple of things to do first that make it somewhat easy, First make sure you have the right fitting for the hose, they come in one and two wire flavors. Next when hose is cut with a small grinder shave the outer edge to a 45 degree angle. Next with a "reamer" which is a small circular drum with cutting vanes, and then do the same thing to the inner part. When you screw on the collar, do NOT tighten it till it stops, just bring it near the top. Put a little Never Seize or grease on the insert and tighten it all the way
 
Should also have said to use a couple pieces of pipe as cheater bars on the socket and wrench.
 
After we dress the hose, bevel the end of the hose and flare out the inside of the hose we screw on the outer collar and then use soap to lubricate the inside of the hose and on the barb that screws into the outer collar. We use a Milwaukee ½” drive impact driver to screw the barb into the outer collar.
