86-95 RX-7 13B 2mm Corner Seal Plug Set — Rotor Corner Sealing Retention Components
The N326-11-C22A is the corner seal plug set for the Mazda RX-7 1986-1995 13B rotary engine. Corner seal plugs are small retention components that hold the corner seals in their rotor corner groove positions during engine assembly and operation, preventing seal displacement under the centrifugal and gas pressure forces acting on the rotor.
Corner Seal Plug Function
Corner seals bridge the junction between apex seals and side seals at each of the three rotor corners. The corner seal plug holds this small sealing element in the rotor corner slot, where it provides the sealing continuity between the apex and side seal systems. A missing or incorrectly installed corner seal plug allows the corner seal to dislodge during engine operation, creating a significant gas leak path at the corner junction.
