XtremepowerUS Adjustable Coupler Connector Adapter Review

Received the goods as promised. I haven't used it yet, but the quality is excellent, the production is reliable. I will post an addendum later. Many Thanks. RP

fit very well, looks good under the hood. I think there's one thing that makes a big difference: words open and close with twist directions. I like it!

The arrows seem to be pointing in the wrong direction, but you have to think about what they're doing, i.e. opening and closing your AC. Once you understand how they work, labels make sense and serve as good reminders. Haven't used them yet but I've tried them on the valves of one of my cars and they fit snug and well. I also love the color coded caps and brass

I've only used this set once on my hose set but it worked great and was even easier to use than my previous quick connect adapters. Check valves are a great feature to make connecting and disconnecting fittings easier. These adapters consist of two functional parts. The first is the automatic shut off when they are removed from the high and low pressure fittings, allowing you to maintain pressure on your gauge set. The second is "valve" in the adapter. While not actually a valve, turning the…
