Tom, there are several different size gland nuts on Packard water pumps and I believe Byron has made them all. Also generic pump wrenches come in a range of sizes, measure your packing nut across flats and compare to what's in MSC's catalog. Remember, Byron's are made to Packard engineering drawing specs, the generic pump wrenches may not be exactly the same but both are made to 30 deg. offset and both are extra thin. I've used both the Packard repro and generic pump wrenches and find they both do the job.
