This steel brake adapter has a male 12x1.00mm DIN bubble flare (convex) fitting on one end and a 3AN male (3/8-24, 37° convex) on the other end. Sold individually.
This adapter fits SAAB-type hydraulic release bearings including our FF1600 Hydraulic Release Bearing Kit for Hewland Mk9, Part No. 163-55. Note that you may need to add a crush washer (sold separately) for a proper seal. SAAB located the seat for this fitting very deep inside the port, so sealing at the port face is more reliable.
