Well, there are a bunch of different ones I have been looking at by a bunch of different companies, but if you go to
PRODUCTS you can see what I am talking about (also bimba air cylinders, parker air cylinders, atlas air cylinders, TRD air cylinders...etc). Also, the fill port size can be specified from a list of several options, but I am going to go with 1/2" NPT....what do you think? Is there anything inperticular I should be looking for in an air cylinder? Is there a difference between these types of air cylinders and the ones that are sold by hydro/air stores online?...
