Duke(WNY),
Thanks for the info. We had been discussing using something like silicone, or GoreTex expanded Teflon Joint Sealant, but were not sure if it would hold the pressure, which according to specs I found on his tractor (White 2-75), on another site, is about 3,000 psi. I just estimated that a 10 ton bottle jack might have about a 3 inch diameter cylinder, that translates to about 2800 psi, so if that has worked for you, it looks like it might work for us. Certainly it can't harm anything, so I will get some Permatex and try it. It does appear that his cylinder is built the same way as you describe a bottle jack. I had wondered if the surfaces had to be lapped together, like the valves in an engine, however, with the threads on the gland nut, it is impossible to lap the two together.
Thanks again for such a quick reply. This is the first time I used these forums, but it seems like a great way to exchange info.
