I have this older Blackhawk floorjack I bought back in the 80's Its a well made professional unit but developed problems so I got a kit and rebuilt it. Now it has a leak issue. The problem is there are no seals or o-rings around the cylinder - either top or bottom. When I assembled it I used some Loctite form-a-gasket but it leaked. When I took it apart this time I found the crap hadn't set up OR the hydraulic fluid reacted and dissolved it. Either way, its leaking. So I'm looking for a better product to use. I don't think silicone is going to cut it AND I hate using that crap 'cause it crumbles when you take things apart and the bits get everywhere. I'm thinking I need a sealant that will set up hard.

Here's the cylinder breakdown As you can see - no seals between the base (42) cylinder (31) and retaining nut (32)

Thanks for that invaluable input. This thing has lasted over 35 years. Let's see where those HF pieces of crap are in 35 years !!
By the way, you can buy complete rebuild kits for these for under $15, I think that speaks volumes.

Of course there's a seal for the ram! That isn't the issue. The issue is: there are no seals on the reservoir cylinder. None in the parts drawing, none on the parts list and none during the initial teardown.
Here's PDF of the jack: parts breakdown and parts list

I love the old made in USA floor jacks & think they are worth rebuilding/restoring every time. I have a NAPA made in USA jack from the mid-80's. Newer imported jacks - I don't trust them. The steel China uses in anything is questionable at best.
