I have 3 15l cylinders and 1 12l twinset.
One 15l cylinder and the twinset is O2 clean and has a DIN 1st stage fitting and I recently converted my regs to DIN.
The other two 15l cylinders (full hydro tested last October) are not O2 clean and have A-clamp only valves (Heisser) which have an M25 thread.
So...
Do I ebay the two non-DIN cylinders and buy one new O2 clean one with a DIN valve, or do I have the two cylinders O2 cleaned and have the valves changed to DIN valves at the same time.
Hmmm...I guess I could have one O2 cleaned and a valve changed and ebay the other one.
O2 clean and a new valve comes in at £60 per cylinder. One new 15l O2 cleaned cylinder (Faber lightweight) from GoDive is £119 plus whatever postage is...
I just can't decide what's best
