Due to the possibility of losing the continuity ball and spring, the following step is
best performed inside a container if possible.
Start the unisex coupling (3) onto the inlet (5). Install continuity spring (7) and ball (6) into hole in inlet (5) and
hold in the compressed position while completing installation of unisex coupling (3) onto inlet (5).
Place a wiping rag beneath the unisex coupling. Adjust coupling position until screw hole is facing up and ball
race (rounded groove) (10) in inlet is centered under screw hole. Insert the 41 balls (4) one at a time into the hole
in the housing by rotating the unisex coupling (3) back and forth while installing the balls (4). Once all 41 balls (4)
are installed, assemble O-ring (2) onto ball retaining screw (1) and install the assembly into the threaded hole to
retain the joint. Tighten ball retaining screw(1).
