You'll need to replace every joint after a few months because the rubber will start to get porous.

Can rubber seals be lubricated with Vaseline?

That is heavily dependent on the sort of rubber. Neoprene is severely harmed by vaseline, and it will eat silicone seals. Nitrile, Viton, and exotic materials work very well with it; but, if the seal is exposed to any hydrocarbon solvent, the Vaseline will easily remove, leaving behind a completely dry seal.
