I have had a 40LB industrial propane tank, similar to one on a forklift, that's full but it has a valve handle with 6 rounded points. The newest BBQ tanks have a triangle handle. The threads look as though they will fit my new smoker propane hose fitting. Will the old tank work on the new grill? Before I lug this beast a long ways I thought I'd ask.....and I don't really want to be a stain on the side of my house.


Wife drives it FAST, hubby fixes it when it breaks.

Be careful, forklift propane tanks dispense liquid propane not gas.

Yup, check to make sure it is either a vapor dispensing cylinder or has a provision for both liquid and vapor and use it only in vapor configuration.

BUT, since it is not an OPD valve you most likely will have problems getting it refilled. Most states not abide by the regulations that require an OPD valve on any cylinder to be refilled.
Not to mention depending on it's age it might also be out of certification and replacing the valve and recertifying will cost as much if not more than a new cylinder.

If you just want to use up the propane the thread will match up. Just check if it's liquuid or vapor draw.

I'll side with vikx on this one and don't be surprised if Suburban wants money to take it off your hands. Local propane dealers and our solid waste authority charge $7.50 IIRC to "recycle" old propane cylinders. The Authority has semi annual "free days" where they take propane cylinder in for free.

Ask Suburban propane about the liquid/vapor. They can also tell you if it's safe to use.

It's stamped on the outside "Horizontal only". And the guage will not work unless it's on its side. Should I not try to use it? I don't want to refill it, I'll give it to Suburban Propane when it's empty, just wanted to see if it would run my smoker, which has to run 10-20 hours a stretch. Can I use it upright for gas, not liquid, or is that not possible?

Except vapor flow horizontal cylinders are subject to the OPD rules. Most horizontal tanks are liquid flow (and an OPD valve doesn't work) that's why I seconded the recommendation to have it checked by a propane supplier. Horizontal vapor only tanks designed mainly for RV's have mounting specific points so the draw tube can't get submerged and do have to meet OPD standards. Not to mention they cost about triple of a standard vertical tank.

That cylinder permanently mounted on an RV, is still, and probably always will be leagally refillable. Therefore it mite be worth some money to someone, or at least not worth paying money to get rid of.

Horizontal Forklift Tanks are exempt from the OPD requirement.

Well I called the 3 propane companies here in the Keys and was not really happy with the answers. One company said no, one said yes, and one said pay us to come look. I gave the tank away to a friend who has 2 forklifts.
