Default Re: Sealing Hydraulic Cylinders?



What are your piston rods made from? This one looks like it's a little rough.. needs a greater polished finish.

From Ari's thread,

A lot better finish on his piston rod (or so it seems from the pic).




I've gotten some "cylinder kits" from Fumotec to make my own cyls any length I want, I just have to cut the barrels & the piston rods to suit my needs and do the necessary machining on the piston rod at each end. The finish on the rods, while looking at in my hands, is much smoother yet than Ari's pic above... whether it's just the picture or an actual difference.. don't know.

Whenever I have to do a repair to a piston rod, I wrap the rod with brass sheet before chucking up in the lathe, prevents any tool marks on the rod that could cause seal failure.
