If anyone decides to do anything with an aluminum propane tank, such as cut it in half for use as a cooker, make sure you do this first:

Remove the valve from the top of the tank and fill it with water for 24 hours. This will get the residual propane out of the tank. This is what they do to all propane tanks before they scrap them. To be extra safe you may want to do this twice.

Don't cut them in half. You could sell them for half their worth and buy a nice grill. Steel maybe aluminum never.

Argh!!! Don't cut them up! If I'd known there were a spare pair of alloys bottles afoot, I would have scooped them up.
We just got our "new" 30 lbs bottles in and besides the initial cost it was pricey to get them filled.
I had to pay a "purge fee for both", then a fill fee of course, and 24 inches of hose to connect regulator with the gas line....$60.00
Our Globetrotter came with 20 pounders (steel), I settled for new 30 pounders (aluminum), would rather have had 40 lb new aluminum for the extra capacity, but couldn't justify spending more. You never know when the extra gas might come in handy.

Wait a minute here...

Did you know that 40# tanks don't have to be converted? Yep, 40# and up are not on the OPD list, unless Aluminum is a factor, which I dought.

Did you know that a 30# tank mounted horizontally does not have to be converted? Yep, true too.

Check the laws and keep this fool who invented OPD scrounging for Yacht gas.

Rest Easy - No Cutting in Half

No way. Aluminum is not desirable for brewing beer. A good quality stainless steel pot is the way to go and that I have.

OPD valve installed

I had one original valve with gauge and electrical sender on a 40# Worthington aluminum tank. The other tank had a Sherwood OPD valve that had already been installed by the PO. I dropped the tank off at a Suburban Propane dealer and he installed the new OPD valve after waiting several weeks for it to come in. Cost was $24.95 plus tax and that included recertification. The 40# aluminum tank looked a little taller than the 40# steel and that is why the dip tube is a little longer than those for the steel.

OPD and 40 lb. Tanks


Everything I've researched says 40 lb. DOT tanks must have OPD valves. The proof will be in the pudding. When I take them in to be filled, the filler will certainly let me know.


Thanks for your input. $24.95 seems very reasonable.

yes 40 lb tanks do need OPD. The rule states "40 lb or less" not 'less than 40 lb.' The intent is safety in portable tanks used in RV's and outdoor appliances.

DO NOT UNER ANY CIRCUMSTANCES TRUST A VENDOR! Especially the fill up guys. It toook me several months to get a local propane house straight because even his distributor was giving him bad information. He finally got hold of the mfg for the straight scoop.

The Dip Tube length is usually noted on the collar of the tank (DT=xx) and you need to make sure you get the proper one (valves also have their dip tube length stamped on them)

WBCCI had a source for a good price for the OPD valves for aluminum tanks. But it is a good idea to get a propane dealer to install them as they often have special tools for the valves (only need a wrench but can be hard to get at). They can also re-certify the tank for another 5 years.

Aluminum tanks are usually well worth new OPD valves although you will loose any level meter you may have had in the old one.
