Benefits of Oil Seals
Areas of application of this rubber are suggested by its outstanding temperature resistance (-55 °C to +200 °C), although this must not be applied to hot water or steam. Although silicone rubber almost matches NBR in oil resistance, it does not match the latter's physical and mechanical properties.
A spark plug consists of a ceramic insulator surrounded by metal components, including a center electrode, a ground electrode, and a metal shell. When the ignition system sends a high voltage electrical current to the center electrode, it jumps the gap between the center and ground electrodes, creating a spark. This spark ignites the compressed air-fuel mixture in the combustion chamber, causing the piston to move and power the engine. 3. Clean the surfaces where the new gasket will be installed.
