Horynar Butane Refill Adapter Isobutane Fuel Canister Isobutane Canister Butane Propane adapter with Exhaust Air Pressure Button/Great for jetboil fuel Canister/Backpacking Camping Stove Adapter

I love these fill adapters. I use them all the time to fill my camping isobutane bottles. Be sure not to over fill or over pressure the bottles, and they can be refilled many times with this adapter. You can put the receiving tank in the freezer for a few minutes to lower the pressure in the tank and allow more liquid to flow in. Just be careful not to over fill. Use a scale and do not fill above original purchase weight ever.

Works great! Use mainly to combine partial fuel tanks into one that is mostly full.

This item works as advertised

Well made good fit on different canisters. Practical carrying case. Would definitely recommend it.

Great portable device to fill smaller containers. No need to stockpile large number of cans

This kit will save you money! Connects to multiple types of fuel cans. Mainly use to refill backpack fuel canisters. I have not had any issues with fuel leaking, and the one way valve allows you to fill the empty canisters fully. Very small and stores nicely in your pack.

Works great to transfer from a couple partial bottles to an empty bottle also allows you to use different types of propane bottles with your ultra light stove.

"I really like these gas canister adapters. Having three adapter options gives me confidence that I won't run out of gas during my camping trips, allowing me to connect my camping stove to a variety of gas canisters. They're lightweight, and the carrying case is very attractive and well-made."
