Process Specification P1013 Revision H November 10, 2020 Alternative Sealing Seat Coining Method An alternative method for coining a sealing seat is to determine the torque required to reach an appropriate seat width. The required torque varies based on the material properties of the installation hole and coining tool and must be validated for each material combination. This is not the recommended method. Reference coining torques for select materials are listed in Table 3. Table 3: Reference Coining Torques STANDARD COINING TORQUES BOSS MATERIAL COINING TOOL THREAD DIAMETER 0.190 Seat...

Process Specification P1013 Revision H November 10, 2020 4.1.1 Dual Sealing A.F.O. Plug Installation The O-ring for a Dual Sealing A.F.O. Plug should be lightly coated with lubrication to give it added protection during installation. The Lee Company recommends using Super Lube O-ring Silicone Grease. Torque values in Table 5 are intended for installing a Dual Sealing A.F.O. against no pressure. For systems where the O-ring is sealing pressure before the plug is seated at the nose seal, additional torque is required to properly install the part. The additional torque needed will be equal to...
