Connects a -6 ORB port to a metric M18x1.5 male fitting.
The Racetronix ADF-6RM1815MF has a -6 AN O-ring boss (ORB) male on one end and an M18x1.5 metric female thread on the other. Screw the ORB end into a -6 ORB port and connect a metric M18x1.5 male fitting to the female end.
Key features

- M18x1.5 metric female.
- Straight one-piece body.
- E85 compatible.
