The desired protrusion on the Fire-Ring is right around .015” (+/- .001) after taking into consideration the thickness of the gasket and the depth of the groove cut.
Typically the groove depth needs to be in the .030”-.034” range depending on the thickness of the gasket being used.
The groove O.D. when using the .105” Rings is typically 4.540”
