Male 12 x 1.0mm Metric Dual Seat to 4AN Male, Stainless

This steel brake adapter has a male 12x1.00mm fitting on one end and a 4AN male (7/16-20, 37° convex) on the other end. The metric end is machined to work with both concave (bubble flare) and convex (inverted flare) female ports, but an included aluminum sealing washer lets it work on flat-faced ports with no flare at all. Sold individually.

This adapter fits SAAB-type hydraulic release bearings including our FF1600 Hydraulic Release Bearing Kit for Hewland Mk9, Part No. 163-55.
