Yup, but to get it filled in the USA you're gonnna need an OUPV valve
.... or you're going to have to get it filled through an 'industrial
supplier' all the time. You will need adapters.

Err, not exactly. Cylinders of 40 pounds or more, industrial (forklift)
cylinders and horizontal cylinders are exempt from the OPD requirement. The
fork lift fitting is different from a standard so you will probably need an
adaptor. Horizontals are exempt because there were no OPD valves available
that would work at the time of the regulation but I understand there are
some now.

Industrial users often draw off gas faster than an OPD will allow and with
more thermal mass they are less likely to freeze up. The regulation was
intended to keep backyard Bar-B-Qers from blowing themselves up with a
frozen regulator. I guess they figured that the average grill would not be
using a 40 pound tank.

BTW, it is an OPD - Overflow Prevention Valve. An OUPV is a six pack
captains license. :-)
