 Refilling 16.4 oz propane cylinders

Does anyone know if you can still refill the small 16.4oz propane cylinders off a 20lb cylinder with the couplers they sell. I would think the float on the OPD valve would close when you turn the 20lb cylinder over preventing the small cylinder from filling. Has anyone tried it with an OPD valve?

The float pulls it open

I have had new bottles leak at the schraeder valve and never seal again, after the first use. I have had my RV fill up with propane because of it.

Refilling them is illegal for a reason, it is extremely risky. Depending on where you store them, you may end up causing some expensive damage, or death of yourself or loved ones.

Ignore my advice, Darwin will have you on speed dial.

I purchased the "Mr Heater" disposable bottle refiller from tractor supply last winter. It works as advertised if you follow the directions. It states to place your 16z bottles in the freezer for 30 minutes or so, all the while having your 20lb at ambient temp. Then screw the adapter on the 20lb, then screw the 1lb onto that. then invert, and open the valve on the 20lb.

It took mine about 3 minutes to fill, although I dont believe they were 100% full. I would assume around 85% or so. YMMV

This has always worked for me .

I've only had one leak and I knew it right away.

Refilling them is NOT illegal. Transporting a refilled one across state lines is illegal...not sure why though. Never heard of someone getting in trouble for it and not sure how it could be proven....so I wouldn't worry about it.



The OPD ones work fine.

Put the 1 lb bottle in the freezer. Put the 20 in the sun and warm it up. Refill one at a time if you have more than 1. I've been able to get it up to about 85-90% full this way.

It seems that almost all of my 16 oz. bottles leak after refill.
Try this: Reload one... put it inside a Ziploc freezer bag, suck the vacuum out ( the best you can ), and zip it shut.... come back in a couple of days.

I keep new ones for SHTF, and reload the ones that I immediately put back into service.... they don't leak if installed - unless the appliance valve is open / faulty.

Millions of the refill adaptors are sold most everywhere.

We see people blowing themselves up every night on Teevee.

Should be possible to use a forklift tank to refill the small ones too.

Forklift tanks are set up to draw liquid propane so you don't have to flip it.

I find this to be true. When I crack one open, I leave it installed on my lamp until empty.

This is my plan

I do throw out any that look bad at all

Thanks for the replies. I'll head down and pick one up now that I know they still work. I'm not too concerned about leaks. I picked up a Lehr propane powered weed eater and will only be refilling the ones I use on it. For those that say the valves will leak, Do you just leave the bottle on the device until it is empty? The refill device should not be any different from the device you are using in respect to causing the valve to leak. I would think you would have the same issue with partial bottles.

This reminds me...i cannot find my refill adapter. It's dug in as deep as an Alabama tick somewhere?
Need to find that bugger before the zombies do.

I never experienced any leakers, but, I did only refill ones that were "like new" and clean.

I found chilling an empty small bottle helped in the filling process.
