Review: I was initially skeptical about safely connecting a 5-gallon propane tank to a portable grill designed for disposable one-pound cylinders. That skepticism is now gone. The connection worked perfectly—easy to install, secure, and completely leak-free. Tools not needed.
Review: This is the perfect size for any table to tank situation. Looks to be made from nice quality. The connection points hold up well to the tank, with no issues of leaks. Functions just like it should. For the price this hose was worth it.

I was a little skeptical that I could safely hook up a 5 gallon propane tank to my portable grill that was designed for a disposable one pound cylinder. Skeptical no more. This worked perfectly, easy to install and safe with no leaks. Didn't even need a wrench.
