- The BR7EF spark plug, manufactured by leading automotive component producers, is designed with precision and durability in mind. The 'BR' in its name denotes its 'Resistor' type, indicating that it has a built-in resistor that reduces radio frequency interference, ensuring smooth operation and preventing electrical system malfunctions. The '7' signifies its heat range, which is ideally suited for a wide variety of engines, providing optimal heat dissipation for efficient combustion. Lastly, the 'EF' denotes its electrode configuration, featuring a fine wire center electrode, promoting better ignition and improved fuel economy.
- The composition of nitrile rubber, which is a blend of acrylonitrile and butadiene, gives it its unique properties. The percentage of acrylonitrile (nitrile) in the compound determines the oil resistance and temperature range of the seal. A higher nitrile content generally indicates better resistance to oils and solvents, while a lower content provides better flexibility at low temperatures. For instance, a nitrile oil seal with 50% nitrile content is suitable for general-purpose applications, while seals with 70-90% nitrile content are specifically designed for high-temperature and oil-resistant environments.
