Dip Method
NOTE:
This method works best with Face Seal o-rings, but
will work for all o-ring fitting types.
The following is needed to correctly oil the o-ring in this
manner:
• A small leak proof container
• Sponge cut to fit inside the container
• A small amount of hydraulic oil to saturate the sponge.
1.
Place the sponge inside the container and add
hydraulic oil to the sponge until it is fully saturated.
2.
Dip the fitting into the sponge using firm pressure.
Upon lifting the fitting, a small droplet will form and
drip from the bottom of the fitting. This should signify
an even coating of oil on the fitting.
3.
O-ring Boss type fittings will require more pressure
in able to immerse more of the fitting into the satu-
rated sponge. This will also cause more oil to be dis-
persed from the sponge.
Spray Method
This method requires a pump or trigger spray bottle.
1.
Fill the spray bottle with hydraulic oil.
2.
Hold the fitting over a suitable catch can.
3.
Spray the entire o-ring surface with a medium coat
of oil.
Brush-on Method
This method requires a sealed bottle brush.
1.
Fill the bottle with hydraulic oil.
2.
Using slight pressure to the body of the spray bottle,
invert the bottle so the brush end is in the downward
position.
3.
Brush hydraulic oil on the entire o-ring, applying an
even coat of oil.
