I used it as a cushioning agent O ring of the connection part between the main body of the chamber and the silencer and used it.
It seems that there is no problem with heat resistance because it is used less often.
Even if you are using the new genuine O - ring, it is a scooter part with a somewhat precise degree so that grease scatters from around the clutch center spring, so cut this rubber sheet in a circle and pinched it under the spring seat.
The scattering of grease almost disappeared, and it became easy including the grease-up time and maintenance.
I would like to change the thickness and make it aligned.
It is very helpful to choose the thickness for use as a sealing material.
In mass retailers and trading companies, it is often a case to purchase batches, and it is very good to be able to purchase in small amounts according to the application.
There are no problems, no problem with no brands.
