The stuffing box must be free of any previous packing. -
Clean all components including stuffing box and gland. Use an approved cleaner if necessary.
-
Inspect tube and stuffing box for excessive pits, nicks, burrs, cuts, and scratches, which may act as a path of leakage. Repair or replace parts as necessary.

Repeat step 5 until all sealing rings are installed including the top ring (See Figure 2). Be sure to install rings in the correct sequence. Seat each ring individually with a tamping tool. Stagger joints 90° apart.
CAUTION: Care should be taken to avoid damaging ring lips -
Reinstall the packing gland until finger tight. Take up gland nuts one full turn to properly spread lips and establish a seal. Adjust packing gland nuts as necessary. After several operations, readjustment of gland nuts may be required.
