Works very well to convert my small tank to a large one. It is well made and easy to install. Very good fit without leakage. Great for the price

Great for refilling propane canisters. Easy to use and holds up well with no leakage.

Works great. Easily install and remove bottles to refill without changing main tank position or need to close valve on main tank.

Many people have asked and complained about lack of instructions, and it doesn't fill the tank, or fill it all the way. The easiest way to use this in a timely manner is to ensure that the big tank is at a higher temperature than the small tank. Increasing the temperature will increase the pressure (ask your local chemistry teacher). Increased pressure in the big tank will push the liquid into the small tank.The big tank MUST be upside-down. These tanks are designed with gas outlets (on the top) not liquid outlets (on the bottom) so to get liquid out you must flip it and use the gas outlet as a liquid outlet.It works better if the small tank is upside down too. I think this has to do with the cooling effect of the propane boiling as it passes the restriction and enters the small tank into lower pressure, but I'm not sure, it does work better though.Not all propane is made the same! At the same temperature your new propane may be at lower pressure than the old propane. If this is the case it can backflow, or if the big tank is colder. It works quite well all the time if the big tank is warmer.If the small tank is completely empty it will quickly be warmed up by the propane from the big tank, and it still may not fill completely. In this case I fond it works well to fill the tanks in two stages, cooling them in an ice bath in between. I generally fill several at a time, rotating them through and filling each twice as needed with an ice bath in between.This works very well, so BE CAREFUL NOT TO OVERFILL THEM!! If they are completely fill, and it warms just a little they WILL leak or rupture.The best thing to do is use a scale and fill them by weight. This means one pound from EMPTY. I know, I just told you it works better if you don't empty them every time, or fill them twice. If you are going to refill these tanks it is a good idea to weigh each one empty and write the weight on the tank in paint or permanent marker. That way in the future you can refill them safely without making sure they are empty first.NOT ALL TANKS ARE MADE THE SAME EITHER! So it is not a good idea to just weigh one and assume they are the same, they should each be weighed.When you are done filling the hose will be full of liquid propane. If you close the valve on the hose (at the small tank end) and turn the big tank right side up leaving the valve on the tank open and let it sit for a little while some of the liquid will return to the tank. This is especially true if the hose is in the sun or a warm place as the propane in the hose will heat up faster than the tank.If you know how to use it it works great. I only gave it 4 stars because the valve packings do leak. For me they didn't start leaking until I tried using it in cold weather, but now it leaks slowly regardless, and drips liquid propane if its cold. I imagine the packings could be replaced with lower temperature, more robust variants, but i have not really looked into it. Doesn't seem like the manufacturer has eitherI only use it in the summer now, outdoors, but its still worth 4 stars to me, worth the price after refilling 5-6 bottles. It should probably only be used outdoors anyways, and the small bottles shouldn't be trusted indoors for a while in case they didn't reseal properly and are leaking.I like the convenience of the hose since not all big tanks are made the same either, and sometimes the outlet is not lined up with the gap in the protective collar so the small one piece versions don't fit.

The Refill Adapter for 1 lb. Propane Tanks is a practical and cost-effective tool for those who frequently use small propane cylinders for camping, grilling, or other outdoor activities. This adapter allows you to refill your 1 lb. propane tanks from a larger 20 lb. tank, saving you money and reducing waste.One of the standout features of this refill adapter is its sturdy construction. Typically made from high-quality brass, it ensures durability and longevity. The solid build provides a secure and leak-free connection, which is crucial for safety when dealing with propane.The design of the adapter is user-friendly, making the refilling process straightforward. To use it, you simply attach the adapter to your larger propane tank, then connect your 1 lb. tank to the adapter. The process requires inverting the larger tank to allow the liquid propane to flow into the smaller cylinder. This might sound complex, but the adapter's design makes it relatively simple, even for those new to refilling propane tanks.Another significant advantage is the cost savings. Purchasing a refill adapter is a one-time expense that quickly pays for itself, as refilling 1 lb. tanks from a larger, cheaper propane source is far more economical than continually buying new small tanks.Environmental benefits also come into play. By refilling your tanks, you reduce the number of disposable cylinders that end up in landfills, making it an eco-friendly choice.It's important to follow all safety guidelines when using a refill adapter. Proper ventilation, checking for leaks, and ensuring all connections are secure are essential steps to safely refilling your propane tanks.Overall, the Refill Adapter for 1 lb. Propane Tanks is an invaluable tool for outdoor enthusiasts and anyone looking to save money and reduce waste. Its durable construction, ease of use, and cost-effectiveness make it a smart investment for regular propane users.

Works great, we'll see how it holds up.

This item worked so much better than smaller type that just screws onto the lp tank. It also makes filling up multiple 1lb tanks easier
