Step 5 · Replace Packing Material
With the packing nut removed, you can now access the packing material around the valve stem. Use a small pick or a small flathead screwdriver to carefully dig out the old, compressed packing washer or graphite string. Be careful not to scratch the brass valve stem. Once the old material is removed, clean the area. Install the new packing washer by sliding it over the stem and seating it firmly. If using packing string, wrap several layers tightly in a clockwise direction around the stem until the cavity is full.
