Procedure for Installing Hydraulic Fittings
and Hoses
Do not use any type of sealant or tape on the fi ttings
or hoses. These materials could damage the product.
Always use two wrenches to ensure proper tightening
of fi ttings and hoses.
Use the following procedure to install SAE O-ring
fi ttings in valve block and rams.
1. Turn jam nut on fi tting as far back as possible.
2. Lubricate O-ring with clean hydraulic fl uid.
3. Screw fi tting into port by hand until the washer
contacts port face and shoulder of the jam nut
threads.
4. Unscrew fi tting to proper position no more than
one full turn.
5. Using two wrenches, hold fi tting body in position
and tighten jam nut until the washer again
contacts port face, then tighten an additional
1/8 to 1/4 turn to lock fi tting in place. Final torque
on the jam nut should be approximately 20 ft-lb.
Use the following procedure to install hydraulic
hoses.
NOTE: Overtightening JIC hose fi ttings will result
in a fractured fi tting.
1. Screw fl are nut onto fi tting fl are and hand tighten.
2. Align hose so there are no twists or sharp bends.
3. Using two wrenches, hold the hose in position
and tighten fl are nut 1/8 to 1/4 turn beyond hand
