Refill Disposable Propane Tank from a Standard BBQ Cylinder

Step 3 Collect Empty Disposable Cylinders

I collect empty cylinders form the campgrounds I visit. Most of the peoples trow them away in the recycling basket I collect them. I also collect the plastic caps because I always store my cylinder whith them to protect the tread and the Shreader valve. Look for bottles that have not dents or rust and the ones that are not to old (the production date is stamped on the bottles)

There are 2 types of disposables tootles :

Type #1 With plastic Base (Coleman Type)

Type #2 With metal Base

I have a preference for type #2 because the metal base wont go off the bottle like the plastic cap but both type work. They have different empty weight and we gone a check this in step #6
