I build pneumatic high security locks and use SMC push lock fittings almost exclusively. But I don't like the really rigid PVC air line because it can crack easily, so I use a premium quality urethane (above DOT specs I believe). Don't forget they have 24vdc valves and flow controls too, not just fittings. Want controlled speed of a cylinder or air motor?
