I have a porta-power pump set up with a collection of adapter fittings
to pump out pistons. Sometimes it's necessary to seal other ports with
plugs or clamps. 1500lbs of hydraulic pressure will almost always move
them-- :-). Of course, I have occasion to do this fairly frequently, so
the investment gets amortized. But if you have (or a friend has) a
porta-power, the adapting fittings would be pretty cheap compared to a
new cylinder. Or maybe you need an excuse to buy another tool. ;-)
