Female 22 x 1.5mm Metric Convex Seat to 10AN Male, Steel

This steel adapter has a female DIN M122 (18x1.5mm, convex Globeseal seat) on one end and an 10AN on the other.

The two-piece design allows you to hold the adapter while screwing down the female threads. This avoids damage to the sealing surface, but it requires a DIN 7631 60° or DIN 3902 / Millimetrique 24° concave seat on the male fitting (the Globeseal seat is not designed to work with Japanese JIS 30° seat). It cannot be used with a crush washer. Sold individually.
