What Does G2 Mean for You?
![Superior Reliability](/media/images/Superior_Reliability.width-930.format-webp.webp)
Superior Reliability
Features our highest operating ratio of 95 percent, allowing production facilities to run at full capacity without worry of altering burst pressure.
![Laser Ablation](/media/images/Laser_Ablation.width-930.format-webp.webp)
Extraction Scoring
Opening feature is laser-ablated or milled, not scored, providing an ultra-reliable line of weakness not found in work-hardened scoring methods.
![Life Cycle](/media/images/Life_Cycle.width-930.format-webp.webp)
High Life Cycle
Superior cycling performance for processes running from full vacuum to 95 percent of burst pressure. Extremely high cycle life profiles available for less demanding cyclic conditions.

Backpressure/Vacuum Resistant
Concave surface faces the process side and can withstand full vacuum without added support; also ideal for in situ testing of pressure relief valves.
