With the packing nut removed, you can see the old packing material around the valve stem. Using a small pointed tool like a dental pick or a very small flathead screwdriver, carefully dig out the old packing. It may be a single rubber or graphite washer, or it might be a fibrous, string-like material. Clean the area thoroughly. To replace it, you can either use a new packing washer that is an exact match for the old one, simply sliding it over the stem into place. Alternatively, you can use graphite or Teflon packing twine. Tightly wrap the twine around the valve stem in a clockwise direction 3 to 4 times, filling the space where the old packing was. The clockwise wrap prevents the twine from unwinding as you tighten the nut.
