1. Total indicator Reading between groove and adjacent bearing surface.
2. These groove dimensions are for compounds that free swell less than 15%. Sutibable allowances should be mde for higher swell compounds
•For max. allowable clearance, refer to fig 22 to determine value based upon pressure requirement and compound hardness.
•Maximum clearance should be reduced by 1/2 for compounds exhibiting poor strength such as silicone and fluorosilicone.
Male plug dimentsions and female throat (bore) dimensions must be calculated based upon maximum and minimum clearance gaps
