Rationale: ADD CODE LETTER A OPTION FOR FITTINGS WITHOUT BLUE PTFE COATING OR PAINT ON THE RING. FITTINGS WITH UNCOATED/UNPAINTED RINGS ARE NEEDED TO PREVENT COATING/PAINT DEBRIS IN CONTAMINATION SENSITIVE SYSTEMS. ADDED NOTE 14 FOR CLARIFICATION OF UNSWAGED AND SWAGED DIMENSIONS. CORRECTED ERRORS IN NOTES. REFORMATTED TABLES.
