Actually it does work you are trying to hook it up to your stuff without a regulator it goes on to the regulator so it works perfectly
I bought this hose because it specifically said it would fit single use tanks, it in fact does not. It is the exact same hose that comes with the kits and you need a separate adapter for single use 2# green tanks
Hi Lucas,
We apologize if the wording of our product description was unclear! The propane adapter hose is designed to allow you to use our Gas Growlers with propane appliances that would normally run on disposable 1 lb tanks – so the hose is not designed to actually be used with the 1 lb tanks.
A customer service representative will reach out to you. We always want our customers to be satisfied with our products, and we'll be happy to offer you a refund or exchange if the hose won't meet your needs!
