- In addition to its performance and durability, the SSR 125 spark plug is also designed to reduce emissions and improve overall engine efficiency. By providing a strong and consistent spark, the spark plug helps to ensure complete combustion of the air-fuel mixture, which in turn can lead to lower emissions and improved fuel economy.

Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.

This is a specific type of synthetic rubber that’s commonly used in o-rings, gaskets, oil seals, sterile & chemical resistant gloves, and other molded items. Viton has a high density and it possesses the widest temperature range of -40 degrees Fahrenheit to more than 400 degrees Fahrenheit. This is why it’s highly preferred as the best material for higher temperature applications.

JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.

Overall, the cost of new spark plugs can vary depending on a variety of factors. By understanding the factors that contribute to the cost of spark plugs, you can make an informed decision that best fits your budget and needs. Whether you opt for cheaper spark plugs or invest in premium options, it is important to prioritize quality and longevity to ensure optimal performance for your vehicle.
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®.
