Select Versatile Silicone Rubber
for Reliable Performance and
Durable Operation
ONE COMPANY
MANY AUTOMOTIVE
SOLUTIONS
Design with temperature-resistant silicone rubber.
Meet severe-duty service requirements.
These proven, high-performance materials
meet severe-duty service requirements in a
variety of applications with a combination
of mechanical properties and environmental
resistance that many organic elastomers
cannot match.
Typical Application
Application Description
Engine
Anti-drainback oil filter valve
Prevents oil from draining
back into oil pan (reservoir)
through horizontally
mounted oil filter after
engine shutdown. Oil is then
present at engine startup to
ensure immediate delivery
to sensitive upper-engine
components.
Engine
Cylinder head gasket
Gasket between cylinder
head and engine block to
prevent leakage of engine
oil and coolants.
Engine
Oil pan gasket
Seal reservoir for engine
lubricating oil; attached to
the underside of the cylinder
block.
Engine
Rocker cover gasket
Cover and protect valve
components (cam, shaft,
lifters, valves, etc.) of
overhead camshaft engines
and seal oil for lubrication.
Engine
Air intake manifold gasket
Seal intake manifold to
cylinder head. Gasket
allows for sealing of oil,
coolant and air.
Driveline
CVJ boots
The boot is designed to seal
the constant velocity joint
(CVJ) on the driveshaft.
Prevents grease inside
from flowing out and foreign
matter from entering.
