IMPORTANT!
Tighten swivel fitting until the fitting has
significant resistance (fittings bottoming out).
Apply ¼ turn past the resistance. Ensure no
threads are visible.
Step 3:
Using appropriate size wrenches, reference
table below for the female coupling body
and female union nut, tighten the female
union nut, according to the torque specs
below, while preventing rotation of the
female body with respect to the male half.
The nut should be tightened until a definite
increase in resistance, metal to metal contact
occurs, is felt (at this point, the nut will have
covered most of the threads on the male
body). It is important to ensure the male and
female coupling bodies
DO NOT ROTATE during any portion of
the wrench installation.
Step 4:
Using a permanent marker or scribe, mark a line lengthwise from the female coupling
union nut to either the bulkhead or female coupling body. Then tighten an additional one
(1) wrench flat (60°); refer to the marking on the union nut to confirm the rotation has
occurred. The final rotation is necessary to ensure the formation of the leak-proof seal,
between the male and female couplings.
Correctly tightened coupling
The swivel nut end contains one diaphragm
in the center post. The male fitting contains
the knife blades and its own diaphragm.
