The unique design of self-threading screws features a sharp cutting edge that 'taps' into the aluminum, creating a secure and tight fit. This not only ensures a strong bond but also prevents any potential loosening due to vibrations or stress. Their ability to generate clean, precise threads without the need for additional tools makes them an ideal choice for aluminum applications where precision and efficiency are crucial Their ability to generate clean, precise threads without the need for additional tools makes them an ideal choice for aluminum applications where precision and efficiency are crucial
Polytetrafluoroethylene (PTFE, Teflon®)
6 - The material used in oil seals is also important, as it affects the seal's durability and resistance to chemicals and heat
- 7
- Furthermore, the use of rubber offers chemical and weather resistance advantages
It is important for the spark plug to produce a strong and consistent spark in order for the combustion process to be efficient. Over time, the spark plug can become worn or dirty, which can affect its performance. This is why it is recommended to regularly inspect and replace spark plugs as needed to ensure optimal engine performance.

Custom-made rubber oil seal


a7tc spark plug. With a simple screw-on design, most motorbike owners can replace their spark plugs in just a few minutes, without the need for specialized tools or professional help.
However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.
This type of oil seal can withstand only low speed and friction. It is recommended in places where thick fluid or grease is to be sealed. This is not recommended for difficult applications.

On most cars you need not remove the engine to get at the sump . But often you have to raise it slightly and wedge it on its mountings so that the sump moves clear of the front- suspension cross member.
