Yes you can. They make a hose that connects to your grill, and also to a 20# or larger tank. I did the same thing with a grill, but also used it for my torch on occasion. Check a good hardware store. Hope this helps.

Martin answers:

The safest option is to light the appliance and burn off the remaining propane in that cylinder.

The shut off valves on portable camping equipment are not really the most positive shut-off devices in the world, and if you can’t get it to re-seat and stop leaking, this is the safest way to handle it.

EDIT: I Don’t usually comment on other responders incorrect information, but I’m on a roll tonight…

Chris is totally incorrect!!!

First of all…these type of cylinders (not tanks!) are not refillable…

Secondly…You never release gas to the atmosphere! The first rule of propane handling is that you never extinguish the flame unless you can control the flow of gas. If you allow the gas to escape and it finds a source of ignition somewhere, you will have a violent and rapid burning of fuel that you will definitely not enjoy!

Burn it off under controlled circumstances and remove the possibilty of an uncontrolled “explosion”
Take it from an experienced professional…Please!

Edit2: I’m not going to engage a huge argument here Chris…Those cylinders are classified as “single-trip non refillable”. They do not have a tare weight stamped on them, so you have no way of knowing how much fuel you are transferring into them. You could easily overfill them. Just because someone makes a fitting that can do it, doesn’t make it legal to do so. There are other examples of products out there that are sold but are either dangerous or illegal to use. And actually it is contrary to gas code to release an unburnt hydrocarbon. This is a relatively small quantity, but still, it shouldn’t be done.

Edit3: DOT 39 is specific to transportation and does not prohibit the refilling of these cylinders, only transportation of them. But fuel handling code specifies that a cylinder can only be filled by weight, using the tare weight of the cylinder and the water capacity…or by volume.

These cylinders do not have tare weight or water capacity markings on them and they do not have a bleeder to fill by volume. Therefore…you cannot calculate the capacity, or know when it is overfilled. You cannot legally refill them. I’m done with this thread…

Edit4: The one and only reason for my additional response Chris is for the slanderous remarks. I do not have multiple accounts! The “thumbs down” or “thumbs up” were not my creation. They were earned from other people viewing this thread. I am a professional in my field, and very proud of it! My priority is to educate people…not provoke arguements or irritate other responders. Obviously that didn’t happen in this case. My apologies are humbly offered. But I do stand by my previous statements.

Mr Bridger: This is one of those cases where there is no law that expressly forbids this act, but there are clauses in the fuel handling codes that have requirements that cannot be met when using these devices. The heart of the matter is that there is no way of knowing how much liquid you transfer. There are lots of other examples of dangerous products that you can buy. For example there are kits to convert old refrigerant bottles into air tanks. This is another very dangerous practice. But you can buy the pieces to do it! Some money is not worth saving from a safety standpoint.

At the place where they sale RV’s. They have parts Department.They have all kinds of parts for various grills !!

Martin answers:

If it is a self igniting type turn the dial a little bit further and it should stop clicking if it is not you may have a bad pressure regulator which could be dangerous
