Application of Silicone
Gasket Material
WARNING
Small amounts of acid vapor are present when
applying silicone gasket material. To prevent
possible serious personal injury, make sure there
is good ventilation in the work area. If the silicone
gasket material gets in your eyes, flush your eyes
with water for 15 minutes. Have your eyes checked
by a doctor.
The following silicone gasket products can be used on
Rockwell components:
A. Dow Corning Silicone Rubber Sealant, No. 737
Black
B. General Electric No. RTV-1473 Black
C. From Rockwell International:
•
40 lb. containers,
Part No. 2297-F-5258
•
Ten oz. tubes,
Part No. 2297-G-5259
•
Three oz. tubes,
Part No. 2297-Z-6656
1. Remove all old gasket material from both surfaces.
2. Clean the surfaces where the silicone gasket
material will be applied. Remove all oil, grease, dirt
and moisture.
3. Dry both surfaces.
CAUTION
The amount of silicone gasket material applied
MUST NOT exceed a 0.125 inch (3.18 mm) diameter
bead. Too much gasket material can block
lubrication passages and result in damage to the
components.
4. Apply a 0.125 inch (3.18 mm) diameter continuous
bead of silicone gasket material around one surface.
Also apply the gasket material around the edge of all
the fastener holes on that surface. Figure 35.

5. Assemble the components immediately to permit the
gasket material to compress evenly between the
parts. Tighten the fasteners to the required torque
value for that size fastener. See the Torque Chart on
page 38. There is no special procedure or additional
torque required.
6. Wait 20 minutes before filling the assembly with
lubricant.
