This is exactly what you think it is. Good news: it works!

I purchased these when I switched over to kegging. They are easy to use and in the grand scheme of home brewing inexpensive. I have 1 for each keg and 2 back-ups just in case. Never had any issues with the ability to switch out lines or kegs, fits right on the ball lock and the threads allow for easy switching out.

The threading connection makes cleaning much easier and makes me more confident of tight fits. I'd rather not mess with the barbed set up

Being made from plastic, I expected this to break in no time at all. Well, so far it's held up very well. It's very easy to disconnect from the gas line, easy to clean, and makes a good connection each time. I do suggest using some keg lube on the posts to keep everything working correctly.

Works well and is a great way to quickly and easily connect a tube to your soda keg. Just be careful not to push down too hard or the plastic base can strip off shooting the spring out. Make sure to measure the tubing so you know which barbed swivel nut to buy along with this item.
