This .036" compressed thickness with a 4.540" bore fits applications needing a robust, sealant-free joint. Embossed outer layers are coated both sides with Viton to withstand temperatures to 250°C (482°F). The uncoated shim layer can be varied to match thickness needs while distributing clamp load and minimizing bore distortion.
