Flowserve 80 Series Five Star Seal - Manual (Page 6)

2.5 Position the 84/85 with the gland tight against the seal chamber
face. Turn the gland so that the flush tap is as close to the 12:00
o’clock position as possible and so that the flush piping will clear the
bearing frame. Tighten the gland nuts evenly in a diagonal
sequence. Do not overtighten the gland nuts, as this can warp
seal parts and cause leakage.
