I have been using a pipe wrench and a cheap Home Depot Spanner wrench to adjust the packing gland. It is always a frustrating experience just getting the two tools properly adjusted and gripping the two nuts. After reading discussions here and on other sites I decided to buy the Rigid E-110 Offset Hex Wrench. I bought two from Amazon for $30 each. I got to use the tools yesterday and I am thrilled. The tool adjust smoothly and accurately. The grip the nuts without slipping and make short work of what always should have been a simple project.
