Wow - thanks for that explanation. I can clearly see the difference in the high pressure fitting but I'm having trouble distinguishing between the screw-on air and hydraulic fittings - can you point that out for me? I can see two different styles of - I'll call them nuts - on the T fitting at the inboard end of the cylinder. Is that T a different spec than the L coming out of the top of the cylinder?there is one high pressure hose end used in this application it is the bottom left fitting on the valve block. If you look closely you can see it is a lighter color than the rest and it is round where it goes over the hose rather than having wrench flats. that is because it is crimped on rather than screwed on. Some of the other screwed on fittings are hydraulic and some are pneumatic. The hydraulic ones will have a slightly longer body. Hydraulic fitting flares are on a 37 degree angle and pneumatic are on a 45 degree angle so they match the mating fitting. the two types are not interchangeable.
The elbow on the left port of the cylinder is rated for 200 psi air.

One other thing I noticed - the cylinder end of the hose going to the shadow drive appears deformed right next to that fitting going in to the T. That is exactly the kind of vulnerability I was envisioning.
