INSTALLATION OF ADJUSTABLE FITTINGS
IN STRAIGHT THREAD O RING BOSSES
1. Lubricate the O-ring by coating it with a light oil or
petroleum. Install the O-ring in the groove adjacent
to the metal backup washer which is assembled at
the extreme end of the groove (4).
2. Install the fitting into the SAE straight thread boss
until the metal backup washer contacts the face of
the boss (5).
NOTE: Do not over tighten and distort the metal
backup washer.
3. Position the fitting by turning out (counterclockwise)
up to a maximum of one turn. Holding the pad of the
fitting with a wrench, tighten the locknut and washer
against the face of the boss (6).
