Posting this here in hopes that someone will get some use out of it. I have a 4 ton "hydraulic body repair set" AKA porta-power or whatever you want to call it. The Harbor Freight model (think that's what I have, maybe it was from Cummins, QF4 is the part number in any case) and other brands are all pretty similar and not very high quality but they do work, until the seals start leaking. The ram on mine was puking oil and I discovered that there is only one seal on the bottom of the piston. It is called a "u-cup seal" but it was almost impossible to find. Literally several hours of Google led me to an eBay listing. The part is just a hair taller than the original but works fine. https://www.ebay.com/itm/165780449958
The tool kit itself:
This is the ram that was leaking, oil would come out of the right side:
Failed seal on the left, new one on the right:
Part # and size of the new seal. I believe you can order from their website as well as the eBay store.
