Does anyone have diffusion pump oil for sale?

[eigenmax]

I recently bought an old diffusion pump from eBay which I'm fixing up, and need 100cc of Santovac-5 oil (polyphenyl ether) for it. Does anyone have an idea where I can get a small amount (~100cc) of it to a reasonable price? What I've found isn't either shipped to Ireland or too expensive.

Thanks,
Max.

Best price I've found with a Web search is at https://vacuumoil.com/product/santovac-5-vacuum-fluid/ ($200)
No Idea if they will ship to you.

Thanks. I've been searching for cheaper oil (I'm 17 and have a pretty minimum wage job), and I was wondering if anyone had some that they owned for sale. Thanks for the help though, I'll look into that!

That is some serious vacuum the Santovac 5 oil is good for. If you don't really need that low a vacuum there are other oils that could work. Try a Google search for Santovac 5 equivalent.

Would the equivalent of Dow Corning DC-704 or 705 silicone oil provide vacuum adequate for your needs? If so, it is cheaper than Santovac 5, and shipping shouldn't be a problem.

I was considering using DC-704, as I can get it for a lot cheaper. I think it ought to work.
