| 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 | ||||||||||
