- In conclusion, the price of car spark plugs can vary widely depending on the type of plug, the quality of the material used, and the brand. While conventional spark plugs are relatively inexpensive, performance spark plugs and those made from platinum or iridium can be much more expensive. When choosing a spark plug, it's important to consider your vehicle's needs and budget, as well as the quality and reputation of the brand.
Although it does have a higher tensile strength and longer wear times than other materials, it is recommended to be used in dry-running applications sparingly or intermittently.
Different Types of Oil Seals
The Ultimate Guide to Oil Seals
• Compact design


Proper techniques and diligence during oil seal installation will result in what seems like an unremarkable situation – a component holding its lubrication. When something you’ve installed works effectively and quietly, you know you’ve done it right.
Of course, all rubber materials and seals will provide a range of benefits; however, you will need to consider chemical compatibility, sufficient temperature ranges, pressure ranges, and more.

PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
Maintenance and Replacement of Oil Seals:
Silicone oil seals, which are also called VMQ, have strong resistance to temperature, which ranges from -140 degrees Fahrenheit to 392 degrees Fahrenheit. They are also resistant to ozone, light, and harsh weather conditions. Silicone is frequently used in hydraulics and pneumatics, as well as in the food and medical industries. Due to the material’s transparency and flexibility, it’s commonly chosen for the manufacturing of o-rings, molded parts, and flat seals, as well as electrical insulators.

aircraft spark plug. Over time, spark plugs can become fouled with carbon deposits, oil residue, or other contaminants that can affect their ability to generate a spark. It is essential to clean or replace spark plugs as needed to prevent these issues and maintain optimal engine performance.
