Performance Advantages

· Stopper Technology: Features a specialized "fold-over stopper" layer that provides a torque-limiting surface to prevent combustion seal yielding.

· Advanced Coating: Embossed outer layers are coated on both sides with Viton (a high-temperature fluoroelastomer), ensuring a micro-seal against fluids.

· Increased Seal Height: The multi-layer spring construction compensates for head lift during extreme cylinder pressures.
