The Pre-July 2015 poppet sail O-ring in this o-ring repair kit is specified as 015-70, meaning it is thicker than the version used after July 2015. The "015-70" refers to the O-ring's size and durometer (hardness), which ensures a proper seal in older Fusion Engines, helping to prevent leaks and maintain performance.
