So I picked up a rivet puller at HF, it calls for some internal hydraulic fluid. I can't find it in small quantities, I need 2 ounces not 2 gallons. Has anybody got a suggestion for a substitute that will do the job? Thanks, Jay

I used brake fluid from the local auto parts store in mine. The pint (?) cost $5 or so.

I was able to buy the hydraulic fluid at Harbor Freight when I bought my pneumatic rivet puller. I had to ask for help finding the stuff, but they had it in a 15 fl oz bottle.

Here it is:

I?ve used hydraulic jack oil. I paid $4.99 for a quart at my local auto parts store.

ATF will work.

If you have some 5606H fluid, it?s s great hydraulic fluid for riveters, and jacks too.
