OK, any idea what these are?

I simply can't find the answer but I'm sure someone here must know. The diameter of the inner tubing is 5mm (sorry about the dog hairs on the 1st pic , it's that time of year :/ )

Refrigeration pipework fittings? Skirting heating fittings?

I really have no clue... Hoping somewhere here knows. I've acquired a big box full of them but don't know what, if anything, I can do with them.

Look like they arethefitting used on air handling unit heating battery coils thicker gauge as they are brazed or silver soldered......regards Turnpin

They look like refrigeration fittings for making evaporator or condenser coils.
No real use to anyone unless you manufacture coils.

Sell them to scrap yard.

Thanks for replies...Seems they are 'Crossover Copper Bends/Fittings' used, as you say, for air conditioning...I've found them online once I knew what to look for specifically. Appreciate all the help, best ring the scrap man
