Another home built splitter question.

[2ridgebacks]

I have run across a number of cylinders that I am consider for a splitter build. They are 5" diameter w/a 3 inch shaft. They are double acting and supposedly brand new. They have screw on caps though. That is throwing me for a loop. Are they indeed hydraulic? Maybe pneumatic? Are they a low pressure cylinder?
Other info: 36" stroke (yeah, a little long), and $225. Anybody wanna know where to get one?

3" ram? nothing will bend that.

Nothing wrong with screw on caps. We have them much larger than that on very large log handling equipment.

External thread caps are among the best cylinder designs. A the pressure tries to expand the bore the threads hold tighter. intenal threads are common to. With a 3" ram I doubt its a air cylinder. Any idea on the packing style, port size and pressure rating?
Where can I get one?

I'm guessing the size of the port opening to be near 1". I have no idea on the pressure rating. They are in one of these out of the way industrial salvage yards. The guy that runs the place seems like a straight-up old timer, which is good. He claimed that they are $1k cylinders new. He bought these and many others surplus. They are in Louisville, KY. I didn't take the time to dig them out of the pile and look for any I.D. on them. Maybe I should have.
