A straight hydraulic adapter from Brennan Industries, the 20MFS-16MP Straight connects a 1-1/4 inch OD tube end to a 1-11/16-12 male thread on one side and a 1-11-1/2 male thread on the other. The face-to-face length measures 2.27 inches, with a 1.750 inch hex for secure wrench engagement during installation.

Drill dimensions of 1.024 inches on the A end and 0.938 inches on the B end reflect the respective port sizing for each connection.
