Key Features:

• Multi-Layer Steel construction with multiple embossed layers of stainless steel
• Proprietary high-temperature coating on outer layers for superior sealing
• Viton rubber coating provides excellent fluid resistance
• Requires less clamp load while reducing bore distortion
• Load-controlled embossments conform to surface irregularities
• Active combustion seal on multiple layers for maximum sealing performance
