The KEVN®  is calibrated to work best with new or unused 70 durometer o-rings with cross-sections starting with .103” (2.62mm) up to .275” (6.99mm), including the standard AS568 series (100, 200, 300, \u0026amp; 400 series). The tool should not be used for identifying or analyzing failed, damaged, or out-of-date rings, o-rings of unknown composition, o-ring cross-sections less than .103″ (2.62mm), or greater than .275″ (6.99mm), or o-rings other than 70 durometer. It should also not be used for identifying composition of flat gasket surfaces.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlace o-ring on a stable surface.
