I have a cheap 3 piece set I bought off Amazon and have no complaints. I have a set of sharp Channellock picks to remove seals and then a set of OEM brand spoon picks in case I need to push a seal in without damaging the seal.
I've used the good old usa ones (proto maybe?) and I own and use the ones posted (or near identical at least) in first reply and they all work just fine.
After I did 3 of the 13 cylinders on my old 580B I found the ones in the link; also bought the 3/4" drive gland nut wrench and a 3/4" Tekton breaker bar, probably saved at least a couple hours on EACH of the rest of the cylinders... Steve
I’ve got a set, couldn’t tell you the Brand or the last time I used them. The reason I purchased them was because I had a large pallet jack rebuild order and the brand utilized deep glands that housed the Rod cups.
Honestly, I never used the big size much. I could usually bend things around with my fingers enough to get large seals installed. The medium ones got a lot of use with thicker cross-section medium diameter seals. The small ones didn't get a ton of use either, as most small seals were also small cross section and would bend by hand pretty easy.
