MENSI Propane Gas Cylinder QCC Type Adapter with 1/4" Male NPT Thread Regulator Valve

My camper propane hook up is old school and uses the pol hard nose instead of the acme thread and doesn't have a gauge, so I bought this POL soft nose adapter with a gauge instead of trying to replace the original hook up hardware. I screw this into my propane tank and the hard nose pol line screws into the adapter. The adapter worked well. Used it during the hunting season without issue.

This product has saved me a ton of money since I can refill 1lb bottles .

Handy for running my little Coleman catalytic heater directly from a 20# bottle instead of those little 1# bottles.

Satisfactory

EDIT 4/13/23: An 18mm socket fits around the brass fitting inside the black knob. Once I figured this out, I was able to tighten everything together for leak-free use. This is a simple, effective fitting for the right application.Original: There is no way to connect this to a line or other fitting effectively. There is simply not enough room to get a tool to engage the brass piece to tighten securely (especially without damaging the brass), resulting a dangerous gas leak.

Remember to turn the source tank upside down (if you can) and leave it for a while before removal. Because of hurricane Maria we could not get replacement propane bottles. This gadget worked flawlessly. The only thing is that when you connect the bottle and hear the gas transferring you think it's done once the sound stops but it still transfers after that. If you take it off you get a propane bottle that may last a couple uses but if you leave it on for like an hour it will fill to almost full level. This is especially true when the source cylinder is not full. During the hurricane we only had two propane bottles so I used to leave one bottle connected refilling while using the other and it worked perfectly.

Fit 100lbs tank and older tanks I have as well. I use 100lbs tank to heat my toy hauler camper so this will help me not have to refill small BBQ tanks every 3 days and I can use it for my generator as well. Thanks!!

The main reason you but a gauge is to see when your tank is low so you can fill it, right? This gauge said I has 1/4th of my tank left and I ran out while cooking. I have been checking it every other day as I knew it needed to be filled soon but the gauge still said it was 1/4th full so I went to cook and it ran dry.Buy a better one that actually tells you when your tank is almost out.
