I have a small five pound propane tank that came off of a Weber Performer gas grill. I wanted to be able to use this tank while camping for my 2-burner camp stove and portable gas grill. This would enable me to stop lugging around one pound disposable tanks and additionally keep them out of the land fills! Since the tank has the quick connect fitting, I was having trouble finding the part. This part not only will help in getting it filled at my local propane dealer but worked flawlessly in connecting a 5 foot hose to my camping appliances. I was actually told by a propane supplier & welding supply store to forget about finding the fittings! I am happy Mr. Heater makes the part and that I found it here on Amazon! Thumbs up!
