New Updated Propane Refill Adapter Hose 36’’ Propane Extension Hose with ON-Off Control Valve for 1 LB Propane Gas Tank 350PSI High Pressure Camping Grill (QCC Type1 Inlet)

does exactly what its supposed to do, no issues at all and will save you a few bucks right away.

Very pleased with this unit. Very simple and quick to use. I expect it more than recouped its cost the first time I used it to refill the empty 1-lb bottles I had onhand. I did not go through any of the processes to fully refill, such as refrigerating the 1-lb bottles, weighing them before and after, or bleeding off pressure as they were being filled. Therefore I only filled them up part way. However, the refill process is so fast and convenient that I considered it more efficient use of time to accept this and refill as needed. Also, the potential downside of overfilling is so great that I consider it a net positive safety feature not to take the extra steps to maximize the refill volume. Upshot: I would buy again. For anyone who goes through even a few of the 1-lb bottles per year, this device will save them a non-trivial amount of money.

Well made product, easy to use

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 either I 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.

Fast and easy to use. I recommend using heavy gloves to avoid a cold burn.

Likes. Works very well. Anyone having problems most likely doesn't understand the physics so they end up fighting the check-valve which is a safety feature. Due to check valve, pressure in small can must be reached before filling, so open 90 degree cock-valve SLOWLY to permit small can to pressurize, then open fully for fluid transfer, while bleeding air from pressure release valve. (you can find videos for details, but you don't need to unscrew the relief valve). This pressurizing step very important on an empty can or the check valve will trip and transfer will virtually stop. If the can still has some liquid in it, it should already be "at pressure" so you should be able to skp this pressurizing step. (another good reason not to run them dry) I filled three empty (depressured) 1 lb cans in 20 minutes ... and I took my time, double-checking every step, so it could have been done in less time. None of this one or two hours per can stuff. Only dislike is waste of fuel in 36 inch line during take-apart, so filling multiple cans at one time will lessen the impact of this loss which it required to disconnect from the larger tank. The long line does make it easier to manipulate things, so it's an acceptable loss.
