what size are the threads - I have a 100 Sherwood tank & the threads measure 7/7" will this work? thanks Alan
Alan: All DIN valves have the same threads. There are 3 types of DIN valves in the industry today. 300 BAR or 4500 psi rating which is a deeper attachment area and cannot be used with a DIN insert or yoke regulator. 232 BAR or 200 BAR which can be used with inserts & yokes. This adapter will work on all types for filling cylinders only.
Yes this adapter will work on any Din valve.
Yes it should fit. The size is actually 3/4". I don't know why they measure the way they do but this will work. I have used this on multiple tank valves and they work. I would suggest using a hack saw and cut the nipple off the bottom of the adapter. Take the o-ring out of the bottom which mates to the inside of the din valve on the tank and cut the nipple flush with the bottom of the adapter.
This will fit both shallow and deep tank din valves. If your din valve is shallow the nipple will bottom out before it seats if you don't.
