Beware – Proprietary Fitting!
Reviewed in the United States on March 5, 2022
The 90 degree connection is a proprietary fitting and will not connect to standard air hose couplers. I tried automotive, industrial, etc. before coming back and carefully reading the description. The fitting only works with their own bleeder kit, "THIS ADAPTER CAP KIT IS EXCLUSIVELY COMPATIBLE WITH OUR ares 18036 BRAKE BLEEDER SET." Shame on me for not reading the fine print.
Obviously, this is a totally unnecessary design feature and only hurts the consumer. Shame on Ares for playing these games and trying to lock you into their ridiculous ecosystem. However, if you're in a pinch, any brake bleeder pressure bottle will work. Slide the rubber tubing over the fitting and use a compression clamp. It's not as pretty but no leaks, it works just fine.
The cylinder adapter does appear that it would fit a wide range of vehicles and it is well made. So far, it has worked on a 2003 Jeep Grand Cherokee 6.0, 2014 Subaru Forester, and 2012 Mini Cooper S. However, I will certainly think twice before I ever buy anything made by Ares again.
