      If you are using plastic, you'll want to use PE (polyethylene) or PP (polypropylene) for the column.
       
      For rubber seals, use EPDM (perxoxide cured if you have a choice). You can use teflon of course, but as its a plastic, it'll more readily take a 'set' after awhile of being tightened down in a fixture and thus may leak. 
       
      In general, always look for items that are NSF approved for potable water.
       
      These will be 'cleaner' than general purpose / industrial products.
