Leaked. Don’t buy
I use 1/4 inch air line, with squared off ends per spec and pressed the lines onto these coupling. The pull test said they were on secure. They both leaked horribly. Don’t buy.

Fit 6mm air line really well. No leaks.
This was a perfect fit for the 6mm air line I need to repair.Used on a 2013 Range Rover front strut line.
