Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.
The care taken during the installation process will pay off by allowing the seal to work quietly and operate efficiently behind the scenes of your application.
Remove the cylinder head (See How to remove a cylinder head ), carefully peeling off the old gasket from the head or block. Make sure no dirt or carbon falls into the engine.
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
Have two plugs, such as old pencils, ready to fit the pipes. Unscrew the pipe connections and plug them at once.
In general, oil seals should be selected in the order of priority indicated in Table 1.
Although extremely flexible, silicone does have some disadvantages. Many silicone compounds have poor tensile strength, tear resistance, and abrasion resistance. If you are looking for a material that offers a higher tensile strength, while still offering high temperature resistance, look no further than Viton®.
In addition to their sealing and durability properties, natural rubber gaskets also offer excellent resistance to a wide range of chemicals, including oils, solvents, and acids
. This makes them suitable for use in harsh industrial environments where exposure to corrosive substances is common.
