Magical fix?

[Old560]

Anybody have a magical fix for making a hydraulic jack quit leaking from this point? Harbor freight Jack not too interested in trying to find parts for it. Probably better off just buying a new Jack. I’ve tried power steering fluid with Stop leak in it but that didn’t work.

It should have an Oring on it. My Chineese jack release did. Jim

Yep, screw it all the way out and replace the o-ring

Once the O ring is replaced flush the jack and change the fluid as well . It's surprising just how much grit finds its way into the reservoir.

I just bought an air jack with three bags. Used it once and if it lasts I will never use a small hyd jack again. they are more tippy but that makes you use a jack stand or blocks which you should anyway. Lifts in a few seconds instead of minutes as well. Price was the same or cheaper than hyd.

Complete rebuild kits are available for your jack. They come with a new needle and all.

Looks as if someone just kept trying to tighten the needle tighter to get it to stop leaking instead of replacing the O ring. Hope the seat has not been damaged for if it has the jack is worthless.
