Revolution RX-7 Three-Piece Apex Seal

Car Make: Mazda RX-7
Model: FD3S
Product code: RFD3-SA

The genuine 2-split apex seal is processed by discharge wire cutting and divided into 3 parts.

The conventional 3-split seal has a large cutting allowance and finishing allowance when the discharge wire is processed with a thickness of 0.2 mm, and the difference in length between the Apex under piece and the main piece is large.

This time, it became possible to process 0.2 mm wire with 0.1 mm, and the cost and accuracy were established, so it became possible to commercialize it.
