What Adapter Fitting for Master Cylinder 4747100 and 3/16 Inch Brake Line?

Question

Question:

Please provide brakeline-to-master cylinder specifications for connector T4750300, i.e., thread size and diameter, male and female. My brakeline connection is 3/16inch tube, male 3/8x24 or, possibly, metric 10.1 ???. inverted flare. It is not compatible with the connector supplied with the actuator, not sure whether due to diameter or thread. I have some space/length flexibility does T4750300 require flared tube connection? Thank you.

Replacement Brass Connector for Titan Disc Brake Actuators - Qty 1 # T4750300 is a 1/8 to 3/16 inch orifice fitting.
