1" fittings fit perfectly in 1.5" sch40 and when I say perfect... I mean perfect. Yes, that means caps too. I would recommend using a coulping and 2 spig plugs so that your neoprene can have a nice flat surface to aid in the sealing of the valve. The length of the coulping is also a nice length for the piston and by using 2 plugs... you reduce the dead volume that you have to pilot.

Milk caps fit inside 1.5" pipe, just screw 2 or 3 together.
I took a D or C cell battery and wrapped it in duct tape until it fit with half of a rubber ball glued onto it.

No it is rubber. It can be turned into thread and cloth made from it.

Like Spud Stuff said, neoprene is a rubber but can be used as a fabric like in waders.

Any hard but yielding rubber will do. Neoprene can be bought as gasketing sheets in your plumbing section. Quick caps from the same section works well.

No, you don't have to use a spring. One of the more talented designers never uses springs. However, you can use one, it depends on the OD of your piston vs pipe ID. This is all available via the search engine.
