In the coming weeks you will notice a visual change to three Hypertherm plasma HPR shield caps. Item numbers 220637 (pictured), 220398 and 220173 will have one black O-ring change to red. This change allows Hypertherm plasma manufacturing facilities to differentiate HPR product line O-rings from other product lines that have similar, but slightly different sized O-rings. This change is purely aesthetic and there will be no dimensional modifications to the shield caps or effects to cutting system performance.
