Great quality and perfect fit
Excellent quality. I used this product to repair a water dispenser line in the door hinge of a refrigerator. Installation was super simple and is definitely an upgrade in my case.

Just what I needed
Works perfectly on the air suspension on my 2003 mercedes e55. Works just like air brake fittings on big rigs

High quality
High quality. They have No center post so I was able to connect two 1/4” OD air lines together even though they had different ID measurement. One had double the thickness wall so the ID was very small and would not work with a center post.

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.

Not worth it.
Had the idea that stainless air unions would be the better purchase. I was wrong. They do not seal,do not hold air...do not give me any peace of mind to drive my car with air suspension. Not using cheap line. Made clean cuts on the lines. Pressed the lines in as far as possible. Will leak air past 90psi Will not hold.
