Key Features
- Toughened elastomer backup layer engineered to support primary PTFE faces under heavy pressure.
- Absorbs rapid mechanical stroke flexion stress to drastically extend wetted component runtimes.
- Formulated with high memory retention to stay dimensionally stable over millions of cycles.
- Serves as a critical secondary fluid boundary to safeguard the air motor during primary failure.
- Sized to exact 2-inch specifications for a perfectly balanced, snug fit across inner plates.
