On the fitting I just received...the oring is NOT sitting in a recessed groove...it just sits on the flat base
9605S-10-L15-22 | 5/8" JIC Male x M22x1.5 Metric Male (fits 15 mm tube)
The pic shows a recessed cut for the oring seal and the fitting I just received has a flat base with the oring sitting on that....what gives?
