Bought two to hook my propane tanks up to a travel trailer. No issues. You'll need the yellow tape around the threads as well.

These worked perfect for me, I used these to connect my 2 little honda generators to a large gas tank so I can operate them for several days which is much easier to refuel. When disconnected it seals both the Gas Hose and the Gas cap for transportion.

It does what it is supposed to do - transfer propane from a large tank to a small tank - look at some You Tube videos to learn the details of how.  I was able to keep a heater running for an outdoor party that only used the 1 pound propane tanks by refilling them using this - saving a lot of money.

I bought this to set up for my dual tanks to my rv, does not have enough pressure to activate and won't start my furnace. I'm sure this will work on a bbq setup but if your wanting a dual setup for your Rv it won't work.

Works well filled my little tanks tree times put the third time the o-ring broke and smelled like propane had leaked significantly but I was able to get a replacement at HOme depot and should work fine again

I used this for a propane extension for my outdoor heater. It does exactly what I needed, but  I can smell gas sometimes.. I need to replace it.

Follow the instructions!  I first tried attaching to a small propane bottle, then to my grill - no flow.  Instructions say to attach to grill side first, then add the bottle.  Guess what?  It works when you do it in that order.  I bought this in case we ever ran out of propane in the big bottle, so I was well past the return date when I finally tested it.  Thought I was hosed for a minute until I reversed the connection order.

As the need to upgrade to the new connection became a necesssity i bought this and it was so easy and affordable to use i would reccomend this to any one i went 3 weeks without propane and it sucked no one would fill my tank . i spent more on gasoline just searhing for a propane vender who would accomodate my old style tank !!! No tools needed .

Worked great! Used as adapter for large propane tank w/ coleman end and was a cheaper alt instead of buying whole new hose!

Assumes the Tare Weight is the same for all empty 20 lbs tanks, but close enough to know whether or not you need to purchase more propane.

Built solid, but a tad more plastic than I care for personally.

I would recommend buying this item if you want to keep track of how much propane you have on hand or how much you just got from the tank swap you just did at the hardware store.

Don't be surprised that you only get 15lbs of propane in that 20 lbs tank. Seems to be standard practice to only fill tanks  3/4 full. :(

I purchased this connector to hook up the new 3 gallon Five Oceans fuel tank (just purchased from Amazon) to my 115 outboard to winterize the motor. This connector worked as expected, however it did seam a bit flimsy when connected to the motor. Since there were no leaks during the winterizing process and I will not be using this tank for any other purpose I can live with the flimsiness for now. Otherwise i would have given it 5 stars.

I bought it to use for my outboard motor fuel and water hose ties. It works great, really leaves them tight. Using the ties means I only need one size for all of the hoses. Takes a second to put zip tie a hose. Fuel line ties are shaped differently than regular zip ties.

I bought this adapter hose for my Cuisinart grill, which sits on my Cuisinart stand, which holds a standard propane tank.  It seems like these items should go very well together.  One might say, that they are made for one another.

And it's true, I was able to attach the hose to the grill fairly easily, tuck it neatly away with a special clip provided by the stand, and attached the tank without an issue.  It all fit together.

However, the instructions are very careful, as it should be with propane grills, to direct the user to check for gas leaks using a solution of diluted dishsoap.  Seems like a standard CYA move. But much to my dismay, my set up had leaks near the grill connection; and I and had to detach, re-attach, tighten, wiggle ... until the leaks disappeared.  Now since this potential issue was pointed out in the manual along with instructions on how to address it you may be thinking that it seems rather unfair to ding Cuisinart for the problem.

I disagree.

To me it seems like components designed to work in unison should do so flawlessly, that's the expectation you have when you don't opt for the generic brand.  Secondly, stopping leaks seems like a core functional requirement for a hose.  I mean you could use a string to 'connect' the grill and the propane tank.  Delivering the propane to the tank is the whole point of a hose.  So if you have a leak, whatever gas is leaking out is not being delivered to the tank.... hence, fail.

It's true that all hoses can have leaks and it's a somewhat universal problem, but I base my low rating on the fact that I am using a matching grill, the set up had leaks on the very first connection, and it's price.  I had higher expectations.

I bought these to hang tank tops on.  I snap these around a single hanger bar and place the tanks in the ring.  Saves a ton of closet space.
I have some shower curtain holders that stay open (more like hooks) but I wanted to try both as using these would ensure nothing fell to floor.
So far both options are working well.

Not much to say about shower curtain hooks but wanted to leave a review since these were exactly as advertised and that's what matters.

This a adapter allows me to make my own hose setups to use with portable propane grills for camping, hunting, and fishing.

Works great!  Displays propane level to eliminate having to guess how much is left!  I bought two.
