Absolutely!
I just spent hours carefully measuring the 6 seals in my cylinder and looking them up in the herculesus.com catalog.
But my cylinder may be different from your so you’re going to have to cross check the shape and dimensions of your seals carefully.
Also since I’ve yet to place my order at www. herculesus.com , I’m not sure what the designation of ‘10-pack’ or ‘3-pack’ means with regard the price, does it mean the listed price is multiplied by the number of seals per bag. Not sure. I only need one of each.
Here are my measurements and part numbers highlighted:
This is the seal for the old Barnes hydraulic pump w 1/2” shaft, you might be able to find it cheaper than $15.
I’m still looking for E-clips for the inside shafts of the pump. I made gaskets by cutting them out of aluminum foil. We’ll see if this works. Hard to find parts for these old components but I’ve not given up.
Finally to disassemble the cylinder tube and ‘gland nut’ try this trick if they won’t come apart: carefully warm the outside of the steel tube with a propane torch so that you almost can’t touch it , this expands it. Also figure out how to get ice or dry ice on the aluminum gland nut to cool it and shrink it. This really work, the aluminum especially soaks up the coldness. On assembly, put the gland nut and piston in the freezer overnight and heat the tube as before.
