I'm concerned about having the correct fitting that threads into the ABS hydraulic unit. This is the outlet connection that reduces to a 3/8" brake line fitting to feed the rear brakes. The fitting I pulled off doesn't want to thread back on as it is impinged by the rubber seal. There is no flared sealing on this fitting-to-ABS unit connection which seems strange. What do I thread into this bad boy?

Update: Unable to find a replacement fitting. Pulled the valve unit to take a closer look...
The original reducer fitting was the correct fitting. There were enough threads to completely bottom out and get a flush seal against the bottom of the open port. Once on the bench, I was able to force the fitting deep enough into the port to catch threads and fit it into that rubber seal. Fitting also had a rubber O ring to further provide a no leak seal. All back together and waiting to be bled.
