Improving hydraulic bottle jack

Baum Hydraulics in Omaha has about any seal made and they are cheap. 800-228-9222 or 9288

Thanks, I live on the other side of the pond and the cost of shipping small parts here is usually many times the value of the part.
For now I have no particular problem, it was just that I can rarely resist the temptation of improving stuff.
