2.9.9 Assembly Instructions for O-Ring Boss
(ORB) Fittings
1. Inspect components to ensure that male and female
port threads are free of rust, splits, dirt, foreign matter,
or burrs.
2. Ensure proper o-ring is installed. If o-ring is missing
install per o-ring Installation (replacement). Refer to
Section 2.9.17, “O-ring Installation (Replacement),” for
procedure
.
3. Pre-lubricate the o-ring with hydraulic oil.
4. For non-adjustable and plugs, thread the fitting by hand
until contact.
5. For adjustable fittings, refer to Section 2.9.16,
“Adjustable Stud End Assembly,” for proper assembly.
6. Torque the fitting or nut to value while using the
Double Wrench Method.
a. The table headings identify the straight thread
o-ring port and the type on the other side of the
fitting. The torque will be applied to the straight
thread o-ring port.
b. Torque values are segregated based on the material
configuration of the connection. ‘Aluminum/brass
fittings or aluminum/brass mating components’
indicate either the following material
configurations:
• Steel fittings with aluminum or brass mating
components
• Aluminum or brass fittings with steel mating
components
• Aluminum or brass fittings with aluminum or brass
mating components.
7. Inspect to ensure the o-ring is not pinched and the
washer is seated flat on the counter bore of the port.
NOTICE
Care to be taken when lubricating o-ring. Avoid adding
oil to the threaded connection of the fitting. The
lubrication would cause increased clamping force and
cause fitting damage.
